Introduction

Become your inner Sherlock Holmes today!

Our product is a forensic science virtual reality app. This app will give the users a sense of what a crime scene is like and they’ll be able to practice what to do at a crime scene. This app will help those who would like to pursue a career in forensic science. They will be able to get the practice needed to know the basics of crime scene investigation and get the some experience. Jobs in this field like and look for those who have experience in this job. Having this slight experience of a virtual reality app will help people get a job in this field. Professors who teach this subject in college could really use this for their students. Right now, the courts are trying to get virtual reality in there to use for the jurors and for everyone else in the courtroom as well. They will be able to see the crime scene and get a visual of the crime while it was happening to get a sense of the case. There is also a college that has started talking about making an app for forensic science classes.

Learning Outcomes

The objectives for this simulation academically would be to improve one’s skills in the area of forensic science as they continue to learn the skills needed for the job. It would provide instructors the ability to show their students a real life simulation in an environment where there is room for mistakes. This simulation would significantly increase the necessary skills needed for properly assessing crime scenes and allow students to come into the field very prepared and ready for real life experience. This specifically applies to crime scenes and the skills when trying to discover clues and investigate a scene.

The application relates to education as it should be used within schools, specifically colleges, with students in the major of forensic science or criminal justice. It should be used after students have the requisite courses, necessary skills and are pursuing higher level courses that relate previously learned skills into real life experience. This simulation can either be used for practice or professors may choose to use this simulation as an assessment. If used for an assessment, at the end of the simulation a score will be present explaining how well you did in the simulation which would allow professors to grade their students on how well they have applied their skills in the field to a real life experience. However, in this type of situation mistakes are acceptable as it is just a simulation, this allows students less stress as they will be able to get the full experience while they are still learning.

User Experience/ User Interface

The materials/ technologies that we will use is the HTC Vive, which is a virtual reality headset. Virtual Reality crept back up into the public in 2012 after being dormant for so long. Over the course of the next five years, Valve and HTC were joining forces to create the ultimate product. Beginning in 2012, Valve set its mission to create prototype. Valves prototype created a, “low-persistence display was a must. In this case, that meant lighting up a panel for one millisecond and then turning it off for nine milliseconds, in order to prevent ghosting (Souppouris).” In 2013, HTC created a periscope-like Re Camera, which is a mobile camera that does not need a smartphone to use.  Soon, The HTC Vive was born.

The HTC Vive has a life like accuracy while in the virtual world is built down to a science. How this thing works is with a few main components like the grid, the angle, the boundaries, the controllers, and the ‘lighthouse.’ The Grid is what the user’s range is, which has a maximum of fifteen feet. The user must stay in this area while playing the HTC Vive at all times to ensure safety and playability.  The Angle tracks the user and their motions while wearing the headset. The stations that track every move have to be above the user’s height to effectively work. The stations also need to be faced down at a 30 to 45 degree angle. The boundaries can be in a shape not necessarily to a square as the system can work in any kind of oddly shaped room to your desire. The controllers will be able to communicate with the lighthouse boxes, as the lighthouse boxes uses non-visible light to find the objects rather than using a camera. The HTC Vive also has a ‘sweep’ mechanism which will basically ‘sweep’ the area to detect any other people other than the user on the headset. This will help the safety of playing a game on this. Last, the HTC Vive features a ‘chaperone’ system that will help you or any other user not bump into anything while wearing the headset (Peppiat).

                                               Implementation Strategy

When it comes to selling this product, we feel that this simulation will be very successful as there is limited access to crime scene and forensic science virtual reality simulations. We plan on advertising primarily to colleges and institutions who are training their students for careers in crime scene investigations. Since our target audience is colleges and institutions we plan to have our simulation on the HTC vive as it allows precise measurements and a more interactive experience than an app using google cardboard. Therefore, colleges have the money to afford the HTC Vive and would be purchase both the equipment and our simulation. It could potentially be a huge selling point for an institutions forensic science program as it allows students hands on experience before they enter their chosen career field.

There are currently no virtual reality simulations on the market right now but there is various proposed simulations on the internet. Many of the simulations that are proposed are primarily for reviewing or reliving crime scenes in a courtroom during a trial, which is very different from our approach (Hamzelou). A similar virtual reality simulation we found during our research was one proposed by the nonprofit National Forensic Science Technology Center who partnered with University of Tennessee to create a simulation to train state and local law enforcement officers in crime scene training for those entering the field or anyone who may wish to refresh their skills (Kanable). This is very similar to our simulation, except our simulation is looking to seek out a different audience as we are trying to persuade colleges and institutions to purchase our product rather than training facilities. When researching, we found this program was for those already working for a law enforcement program or those looking to complete a simple training program. Our simulation is for those who already have learned the needed skills and have taken prerequisite courses and need hands on experience before entering the field.

As technology rapidly increases, more people are relying on it. As students move into college they are introduced to new technology that incorporates learning, therefore this simulation will fit into the curriculum and style of learning that students are already using. Technology has come a long way over the years and now students have hands on ways of learning through technology and this simulation is a perfect simulation for forensic science students to use.

We plan to reach our customers, who are primarily institutions and colleges, by going around to those schools that offer forensic science as a major and advertising our product to their deans. We feel this will be the most effective method as we can provide an in depth presentation as well as a trailer of our simulation which will grab their attention. We also will send out pamphlets to schools who could potentially be interested, therefore those schools who offer a forensic science major to their students. We feel that these techniques will be very effective and will grasp the attention of our audience best. We do not feel that we will have a problem selling this product as it is a very important simulation needed for learning before entering the career field.

Long-Term Vision

Most people who go into forensic science start out in crime scene investigation. So, for those who are going into forensic science, the demo is going to be focused on main parts of crime scene investigation that most people will have to know. This includes gathering evidence, photography and measurements. You’ll show up to the crime scene and find all the evidence, take measurements when needed and then photograph the crime scene and all the evidence separately. This will show the basics of forensic crime scene investigation in which people will be prepared for what the job entails. The next phase of development will start introducing different disciplines of forensic science. These disciplines include chemistry and biology to start. These will be more interactive and more school oriented. In 5 years we hope to have more disciplines; blood spatter, toxicology, documentation, etc. This will be more for people to try out different disciplines to practice and see what they like if they want to venture off into something else.

Conclusion

Using this application will give college students and trainees in the field a better understanding of how crime scenes can develop and make them better prepared when they encounter a real one. Crime scenes are in a way a work of brutal art that only people with keen eye can decipher the hidden message in it. Our app will make it easier for students to put themselves in the crime scene and be able to see all the hidden clues inside them. Without any virtual reality simulations like this aimed at college students, this could be the app that could open the floodgates to a very profitable market.  Of course, our idea is slightly limited because we want to have the best available one in the quickest time. Having fewer disciplines to start should let us do more with each discipline. We feel that expanding in the future would be better than having everything on release. Our product can help cultivate the next generation of great forensic scientists.

Benefits of Virtual Reality

It’s no surprise that technology is evolving as it is becoming the future of society. Everything that we do from learning is all now technology oriented. From reading academic articles online, solving math problems, or even just having access to the internet for leisure time. Throughout this semester with studying how the internet truly impacts the way I learned I have had different views on whether it’s beneficial or not. From listening to both sides of the argument I believe the internet is incredibly resourceful in the way we learn. Throughout reading the book “Ready Player One” I believe that the virtual reality has impacted the way society learns in school systems in many positive and beneficial ways of society.

In Cathy Davidson’s article. “Now You See It” she reminds us that “The internet offers us the communication means that we need to thrive in a diverse and interdependent world”(page 7, Introduction). Basically, Davidson is saying that the internet opens up many doors for us. Everything such as the web and internet is the world we live in today. That is needed that keeps society going. Everyone who is online is connected in this way such as social media. This is where virtual reality can play a huge role as it’s like we are all living online.

Attending the virtual reality school in the Oasis, Wade shares his in-school experience In chapter 4 of “Ready Player One”. Wade states, “In my next class, Biology, we travelled through a human heart and watched it pumping inside, just like in that old movie Fantastic Voyage(page 48). Wade is insisting that he gets the chance to actually travel inside, throughout a human heart where in reality we actually could never physical put ourselves inside and do that, only watch it through a camera traveling inside. This virtual reality experience is somewhat different than reality. In a way, we are able to do and experience somethings that actually couldn’t be done in reality. However, we are able to do somethings like travel around the world which is something people do in reality, but not everyone gets the opportunity. In this case Wade does not have the funds to travel so in school he is able to travel around the world and learn in that aspect. As well as traveling, in virtual reality you can even visit the past and going back to the future. If we think about it not all students are able to travel and especially relive something in the past or even go back to the future. In this way, it’s a great way to learn from virtual reality where we can actually experience what was once there and even the unknown.

In chapter 4, in the Oasis Wade states that “the OASIS public school teachers seemed to genuinely enjoy their job, probably because they didn’t have to spend half their time acting as babysitters and disciplinarians. The Oasis software took care of that”(page 47). In making this comment, Wade emphasizes that the teachers were able to hold the student’s attention, focusing on learning. When learning, it’s important to be in a good learning environment. In the Oasis all the students are able to concentrate and stay focused on the work rather than becoming distracted by other students or even the area in which you are attending school.  I know that in some cases there are schools that don’t have the funds to get materials or learning tools in which is needed for learning, but in the oasis, you are able to have access to all of that. Virtual reality for schooling is good learning environment space where students will do well in whatever they are learning by the means of focusing and having access to different learning tools.

My own virtual reality experience was informative. During class we had the opportunity to play around with virtual reality on our phones using “The New York Times” cardboard glasses. Watching academic videos was awesome, I felt as if I was there swimming in the ocean with sharks and scuba divers experiencing what they experienced if as I was actually there. Another type of virtual reality I experienced in class was on the laptop with a big head set and glasses. This was extremely exciting for me because I love to travel so I had the opportunity to travel to Paris again. It was neat to actually walk around the classroom but from what I saw I was walking towards the Eiffel Tower, so yet again a great way to learn about landmarks and history in our world.

Since the future of society is technology, we can see how important and beneficial the internet and virtual reality has become. Cathy Davidson emphasizes that the internet and web is how society stays connected, in a way our devices have consumed society and we are living life online. As I read “Ready Player One” I read how beneficial virtual reality really is. Experiencing things, the unknown or even what is there, but never having the opportunity to is great for students who may not have the opportunity to experience travelling. As well has traveling and experiencing the unknown a learning environment is always important to where students stay focused and have access to all the learning tools and materials needed to strive to excellence.

 

Adapting our Education System to the Digital Age

When analyzing how the Internet affects our lives, we discover there are many advantages as well as disadvantages. To ensure these disadvantages are outweighed, it is crucial for our education system to adapt to the recent change in the relationship between technology and learning. This is why we as an administration have to recognize that the Internet is changing our ability to read and research and recognize this change as positive rather than solely focusing on the negatives. As presented in the five articles, it can be concluded that the Internet takes up most of our free time, computer screens can hinder some of our skills if used too much, reading online may not be approached with the same seriousness as reading on paper, and attention blindness and multitasking are issues that need to be addressed. In my opinion, all of these points can be effectively used to reform the education system.

The Internet or computer screens in general are starting to take up more and more of our free time. In my opinion, in order to use this to our advantage, we can create more programs that incorporate computers. Since students are already familiar with computers and the Internet, there is a potential for lessons to be taught faster. However, to avoid the disadvantage of not learning how to reading from texts as well, there should be an even divide between lessons are taught on screens and when they are taught from text on paper. In Nicholas Carr’s article titled “Is Google Making Us Stupid?” he argues that we are more inclined to use screens rather than paper. The Internet is now more accessible and therefore we often rely on it more. As a result, he says we find ourselves more distracted when reading paper books because we are used to reading online. We therefore find the internet more interesting and more useful. This causes us to skim through paper books more frequently because we do not take them as seriously. Hence the title, he questions whether or not this affecting our intelligence or our ability to learn (Carr, “Is Google Making Us Stupid?”).

Although beneficial, if used too much, the Internet seems to have caused some consequences for our generation. In the second paragraph of his article, Carr states that reading used to be easy for him but recently he has noticed a change in his reading. He says that he feels his brain changing because of his recently frequent use of the Internet. He notices that he does not focus as much as he used to (Carr, “Is Google Making Us Stupid?”). He says the internet is “chipping away his capacity for concentration” (Carr, “Is Google Making Us Stupid”). In La Farge’s article titled “The Deep Space of Digital Reading”, he argues “The Internet may cause our minds to wander off, and yet a quick look at the history of books suggest that we have been wondering off all along” (La Farge, “The Deep Space of Digital Reading”). Personally, I have seen a change in my reading since I started reading on the Internet but I agree with La Farge. A change in someone’s reading is an ongoing process, it does not just suddenly happen. I think history proves that reading on line has always caused a few changes in people’s minds and nothing has in the past few years.

Claims presented in Ferris Jabr’s article “The Reading Brain in the Digital Age: The Science of Paper versus Screens” support that reading online may not be approached with the same seriousness as reading on paper. This article was published by Scientific American and therefore takes a scientific approach in analyzing screens versus paper. According to his research, people approach reading on a screen with a “less conducive state of mind” than when they are reading a paper book” (Jabr, The Reading Brain in the Digital Age: The Science of Paper versus Screens). Jabr says that people read less comprehensively and slower when reading on a screen. He also says that there is a sense of accomplishment when book versus reading a text on a screen. This is why I propose that the education system break this common perception and teach that screens can be used just as effectively as paper. Although research proves this, I believe that we as this education system can change this. If schools equally divide when computers are used and when books are used, students will learn the benefits of each and which work for them for different assignments.

Attention blindness and multitasking are issues that need to be addressed in order for our education system to adapt to the digital age. According to Cathy Davidson’s Now You See It, attention blindness is when one can not focus on more than one thing. She says that when our attention is focused on one thing, it is hard to concentrate on another. In other words, multitasking is not always beneficial or effective. She claims that attention blindness happens in all ages and that the Internet is a contributing factor to it. On the fourth page, she says “attention blindness is key to everything we do as individuals, from how we work in groups to what we value in our institutions, in our classrooms, at work, and in ourselves” (Davidson, “Now You See It”). From this claim it can be concluded that attention blindness can be effectively used in the education system if approached the right way. It is already incorporated our classrooms so we have to devise a way to use it to our advantage. Similarly, in Olivia Goldhill’s article titled “Neuroscientists Say Multitasking Literally Drains the Energy Reserves of Your Brain”, she evaluates the impact of multitasking on our generation. In her article she claims that “myriad activities are making us tired” (Goldhill, “Neuroscientists Say Multitasking Literally Drains the Energy Reserves of Your Brain”). She says that we think we’re multitasking we actually aren’t. In other words, we are not actually completing two tasks when we think we are. More than often, we are just focusing on one task rather then the other. We get tired more as a result of multitasking and switching between tasks builds up stress. Certain tasks may also be more draining than others. Her solution is to take breaks in between tasks or just giving up multitasking as a whole (Goldhill, “Neuroscientists Say Multitasking Literally Drains the Energy Reserves of Your Brain”). Based on my experience, multitasking is draining and is not always effective. This is why the administration should teach how to multitask effectively and when it should be used. For example, when doing laundry, a task that is not very draining, reading a book or listening to music may be acceptable. On the contrary, when completing an important assignment, it may not be as acceptable to multitask and students should just mainly focus on their assignment. Although this seems obvious, we as a society and more specifically as an education system still continue to use multitasking in the wrong way and at the wrong times leading to attention blindness.

It can be concluded that the Internet takes up most of our free time, computer screens can hinder some of our skills if used too much, reading online may not be approached with the same seriousness as reading on paper, and attention blindness and multitasking are issues that need to be addressed. All these claims can be used to the education systems advantage if administration devises ways to strengthen the relationship between technology and learning. All five articles prove that although the internet or screens may not always be the most effective way for learning so it is our job to decide when to incorporate it and when not to. When used effectively, the Internet as well as multitasking will help the education system to adapt to the digital age in a productive and successful way.

 

Adapting to the Digital Age

Technology is constantly evolving in our world today. As individuals, we are capable of doing everything by the touch of a single click, including reading journals, solving math equations, and googling answers to our own questions online. This allows us to have so much more access from a machine rather than our own thinking. So, it’s quite common for educators to keep up with society as they adapt to the way students are learning from modern technology. The internet has its benefits and consequences, but I am a strong believer that we should limit ourselves when using technology for learning.  Forcing yourself to read online, as well as multitasking, is much more challenging and equally draining for an individual.

In the article, “Is Google Making Us Stupid?” Carr expresses how easy it is to find information using the internet with all the resources available to us. Although, we cannot depend all our thinking on the internet. Carr and other colleagues claim that it’s hard to stay focused while reading online due to many distractions the internet has to offer. Carr expresses from other colleagues who have stated that, “The more they use the Web, the more that have to fight to stay focused on long pieces of writing” (“Is Google Making Us Stupid?”). Distractions like video ads, music, and notifications that instantly pop up that take your attention away in a snap of your fingers. For example, as I am writing this paper, referencing back to the article I am easily distracting by the ads that are shown and even the notifications that pop up on my screen as well.

While you think you may be the only one who gets distracted when working online, Carr discusses this phenomena in his article stating, “Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I’m always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle” (“Is Google Making Us Stupid?”). In his statement, Carr focusses on the point that reading online can become so boring and can make us become easily distracted with everything the internet has to offer such as social media, checking mail, and just searching the web rather than concentrating on the reading. Coincidentally, distractions could easily get confused with multitasking when working online.

I notice as I read different articles, Olivia Goldhill provides clear evidence similar to Carr’s evidence. Goldhill says, “That switching comes with a biological cost that ends up making us feel tired more quickly than if we sustain the attention on one thing.” (“Neuroscientist say multitasking literally drains the energy reserves of your brain”). She states that switching in between activities and tasks becomes more exhausting rather than productive. She even includes evidence that our brain uses oxygenated glucose which is burning out the same fuel needed to focus for single task. So imagine multitasking in between three different tasks and becoming ultimately overwhelmed—but really it’s your brain chemically over working itself to get everything you need done. Therefore, multitasking continues to make ourselves worn out and equally draining. It is suggested that a break is only needed in between tasks.

Completing two tasks at once is quite challenging when results do not come out as best as they could. Goldhill’s article she says “you can’t do two demanding, even simple tasks, in parallel.” This statement explains that we cannot focus or concentrate on doing two tasks at once because there’s no full attention on the one task that is needed to be done. For example, driving and texting is quite impossible and illegal, because not only is it a distraction, but it’s also putting yourself and others lives in harm’s way. We mentally cannot focus on the road and text because our attention should be fully focused on one thing at a time to get efficient results. Although, driving and texting is illegal and a major distraction, listening to music and driving is different because there’s no physical harm in it, because it doesn’t negatively affect the way we are completing a task. 

In the article, “The Reading Brain in the Digital Age: The Science of Paper versus Screens” Jabr discusses the difference between reading on screen and paper. Jabr makes a good point—that we do read left to right in books while seeing the text as a whole with less distractions whatsoever. It’s a book, it’s in our hands, we turn the pages, our mind is constantly taking information in. For once, we are not overworking our brains with distractions and multitasking. When reading on paper it appears that we have a better way of imagining the text out as well as having a mental map of the text. Turning off all electronics and isolating yourself from distractions is a way for individuals to read a book to get less distracted. In contrast Jabr discusses the effects of reading online. Most digital screens do not always display as a paper book interfering with the way the text is presented to individuals. Individuals will scroll through a digital text, then begin to click on different pages as well as taking the time to go to the search function. Jabr states, “but it is difficult to see any one passage in the context of the entire text.” (“The Reading Brain in the Digital Age: The Science of Paper versus Screens”). Jabr means that sometime it’s better to see the text as whole instead of bits and pieces. Screen display a virtual page where one moment it’s there then gone and on paper we are able to retrace our footsteps.

As society is evolving and becoming more engaged in modern technology, many people suggest we should adapt our education system to the digital age. I’m here to say that we shouldn’t. The internet changes the way we think as our minds become more dependent on it. We lose sight and beauty of information that is physically around us to where we can’t think for ourselves anymore. When reading online, we tend to have a short attention span while becoming distracted by everything on the internet. As humans, we also tend to multitask with several things at one time. In result, we begin to lose focus of what we want to accomplish. With a physical book at hand we are able to see the full picture as well as not losing focus. Reading online and multitasking can completely over work our brains as distractions. However, as we know it, technology isn’t going anywhere, but only evolving as it is the future. Strategies that educators can conduct for students when using technology for reading online would be to limit ourselves from our phones and turning notifications off as we have a better focus off the text.
