The HTC Vive is a virtual reality device, which was developed by HTC and Valve. It is a wearable device and belongs to the head mounted displays' category. It was shipped as the first virtual reality device that allows the user to directly act and physically move in the virtual reality thanks to its position tracking system. The user interacts with the virtual reality by the headset, controllers and the base station sensors. The whole system has to be linked to a considerably powerful computer to achieve smooth image rendering. The safety of the users is secured by the Chaperone system. The system displays the real surrounding when needed and warns the users if they approach too close to an obstacle so as to prevent injury.
The HTC Vive was primarily created as an entertainment device, but its developer has ambitions to educate and enhance the abilities of its users. The use of HTC Vive in business or therapy was taken into account at present. There are also great expectations that virtual reality devices as the HTC Vive could bring a new approach to the visualisation of scientific models. The wide range of its usage is mirrored in the further partners of the project which are e.g. Google, Lionsgate, HBO or BMW
The HTC Vive is fully enclosed but it needs to be connected to a personal computer, hence it is not a standalone device. It has total resolution of 2160 x 1200 pixels and, on the contrary to other headsets, it has an aspect ratio 9:5. The refresh rate of images is 90Hz and the field of view is approximately 110°. The HTC Vive consists of a head mounted display, two controllers, two base station sensors, ear buds and it is shipped with copies of the video games Fantastic Contraption, Job Simulator and 3D painting tool Tilt Brush. The headset is made from black plastic with 32 sensors placed on its surface. The sensors are located into various directions in order to enable a precise tracking of user’s movements. In the middle of the headset is a frontal camera which is a part of the Chaperone system. The optics of the headset is mediated by two Fresnel lenses, which are considerably lighter than standard lenses. The headset fits all shapes of face and glasses can be worn in it since the specific settings are adjusted by a foam lining. Headphones are not a part of the headset. Users could use theirs or they could use ear buds which are shipped with the headset. The headset is linked with user’s computer by cables.
In addition to the headset, virtual reality is affected by two wireless motion controllers. They are crowned by a circular motion sensor and contain buttons and touchpads, which allow various ways of interaction in virtual reality. Recently, the rumours appear that HTC develops an another type of controller, which would be more similar to a human hand, titled Manus VR, but it is not shipped with the HTC Vive at present. The tracking of all the sensors is provided by two base station sensors. They have to be installed in the opposite corners of the virtual reality field, in which the user will be moving. In order to track them precisely, they have to be placed on high and stable spots. The recommended area of the virtual reality field is approximately 2 x 1.5 m (6.5 x 5 feet).
Because of this combination of sensors, the HTC Vive was the first virtual reality device that truly enabled free movement in virtual reality. In order to make the movement in virtual reality as safe as possible, HTC and Valve invented the Chaperone system. It contains several functions which are supposed to protect the users from injury while using the device. Firstly, it shows them a blue network, the boundary in their virtual reality environment, should they leave the area bounded by the base stations. Secondly, it enables the users to see the shapes of the real environment around them upon request through the camera embedded in the middle of the headset. This makes them see whether an obstacle is too close to them.
The HTC Vive could be linked with a mobile phone and users can received massages or send a simple answers while in virtual reality.
The price of the device is 800 USD. In many cases it also requires further investments into a personal computer, since the recommended specifications for such system are considerably demanding. Namely:
- Intel i5-4590 / AMD FX 8350 equivalent or better
- NVIDIA GeForce GTX 970 / AMD Radeon R9 290 equivalent or better
- 4GB or more
- HDMI 1.4 or DisplayPort 1.2 or newer
- 1x USB 2.0 or better port
- Windows 7 SP1 or newer
The HTC Vive’s main purpose is to entertain and educate its users. It also provides a working field for artists, scientists and businessmen. Its possible use in therapy is significantly taken into consideration at present.

Enhancement, Therapy and Treatment
Since virtual reality devices such as the HTC Vive allows simulating situations from Architecture, Engineering or Chemistry, which are safe and realistic at the same time, they possess various possibilities for in these fields of study. In addition, designers in BMW appreciated HTC Vive’s precise tracking, which could simplify their work. The 3-D models are also considerably less expensive than clay models which were used previously.
The researchers claim that virtual reality has a great pedagogical potential. The positive impact which virtual reality has on an educational process was tested for several years. However, they argue that new devices as the HTC Vive could provide more compelling experience. These devices are also more accessible for users.
There are studies of a therapeutically use of virtual reality in cases of stress, post-traumatic stress disorder, attention deficit hyperactivity disorder, and the reduction of pain  which can be applied more or less on the HTC Vive. Nonetheless, a different virtual reality device was used in most of the research. There is, however, one exception, the Deep VR developed an app which reduces stress and anxiety and which was developed and tested on devices Oculus Rift and HTC Vive. Beside the virtual reality device, it requires a snug-fitting sensor, which monitors user’s breath.
The researchers also take into account the treatment of sexual offenders in virtual reality. This could, however, oppose laws of certain countries, which prohibit sexual representations, especially the images of nude children.
The health risks of the HTC Vive could be divided into two sections. One, health issues that stem from virtual reality described under the title of cybersickness. It is a bulk of symptoms, such as headache or nausea. The majority of virtual reality devices could cause these symptoms in greater or lesser extent. Certain reviewers argue that the HTC Vive does not cause them cybersickness, or its symptoms were milder. However, a comprehensive study of this phenomenon and the larger group of respondents is needed for any conclusive claim.
Second, there are health risks which are the result of motion (even though the Chaperone system should avoid a majority of them). The HTC Vive could endanger users by falling over cables or hitting their limbs. The bystanders could also be hurt if they stand too close to the user. All the health risks are carefully described in the HTC Vive’s Safety and Regulatory Guide.
We found no ethical issues related to the HTC Vive directly, but those applicable to virtual reality devices in general could be applied to the HTC Vive as well. Especially video games were intensively discussed recently. Although there are controversies such as addiction to video games or microtransactions, the greatest issue is the violence, which some video games contain. In addition, it was pointed out that virtual reality devices, such as the HTC Vive, make the entire experience more intensive and therefore the negative impact of certain content could be worse.
Public & Media Impact and Presentation
There is a considerably great amount of reviews of the HTC Vive. However, a majority of them discuss certain specific features of them. They identify as a negative aspects of the device its enormous price, its demanding space requirements, the weight of the device, the challenging setup of the device and the fact that really attractive games have not been developed yet. In contrast, reviewers approve that the HTC Vive offers the most appealing experience of VR so far, that it does not cause cybersickness or that its symptoms are milder, and that the HTC Vive provides various use of the device outside virtual game's realm such as engineering, industry or military.
Regarding price, although many reviewer would agree with a reviewer entitled Shanks007 who on Microsoft Store eagerly claims "...this device is worth every penny I spent on it.", there are also voices which argued that the device is too pricey. Lewis Painter from TechAdvisor claim: "We're not so sure about the value of the HTC Vive at this price, especially when you add the P&P price on top of the new price tag, totalling £816.60. It was just about justifiable at £689 and while the HTC is fantastic, we're not sure it's worth this much...".
Since certain apps for the HTC Vive require 15 x 15 feet space, reviewers point out that such a huge space without obstacles is not a commonly found in households. Duncan Bell from T3 remarks: "In fact, I'd go so far as to say that about 2.5m x 2m would be my recommended space. And in most British, urban homes, certainly in London, that is a LOT of space. Then again, you've just shelled out 700 quid for a gaming accessory. Maybe you're minted."
In addition, Vive's headset is quite heavy, as many reviewers reported. Among others an expressive description is provided by Michael Nunez from Gizmodo: "The HTC Vive’s goggles are heavy—noticeably heavier than the Oculus Rift’s. They’re heavier than a bike helmet, heavier than a baseball cap, heavier than scuba goggles, and probably heavier than anything you’ve ever put on your face." However, he adds immediately: "But it’s a small price to pay for walking around in a virtual space, especially if you’re excited about it, so most people will probably disregard the excruciating weight of the plastic headset."
Although certain difficulties with plugging and installing the devices were reported, the majority of objections are directed against SteamVR. As e.g. Adi Robertson form The Verge argues: "Digging through Steam’s system menus has never been particularly convenient, and it’s even harder with a bulky pair of goggles. Especially compared to the simple, locked-down Oculus Home software, SteamVR is the Linux of virtual reality — a powerful system that offers a lot of freedom at the expense of user-friendliness."
Valve's involvement in the project raised a great expectations concerning virtual reality games. They have not been entirely fulfilled yet. For instance Michael Nunez argues "The games are weak. Let’s just hope that Valve steps up to the plate and creates VR games for popular titles like Portal and Half-Life." However, this problem might be overcome in future.
Some of enthusiastic approval of the HTC Vive were already mentioned. Many reviewers considered the HTC Vive to be the revolutionary device in approaching VR. In order to mentioned some examples, Disney's animator Glen Keane publicly supported the HTC Vive highlighting the fact that a user could create 3D paintings throught its app Tilt Brush or Lee Hutchinson from Ars Technica claims: "The fact that you can touch your environment in the Vive—the agency imparted by the fact that you can literally reach out with your hands and do things in-game that you do in real life—overpowers all the other system differences."
As was mentioned in the section "Health Risks" reviewers in general reported that the users of the HTC Vive are not as endangered by cybersickness as users of other VR devices.
The HTC Vive's use in a fields different than VR games was already mentioned in a section "Enhancement, Therapy and Treatment". Adi Robertson especially highlights: "Virtual reality has a long history in fields like architecture, industrial design, and military training, and the solid, no-nonsense Vive can replace older solutions like CAVE rooms at a fraction of the cost."
To sum up, desipte certain objections, the HTC Vive is generally appreciated by the reviewers. In addition, it won several awards.
There was a controversy among the users of the HTC Vive and the Oculus Rift project. The anti-piracy technology of the Oculus Rift made Oculus-exclusive apps inaccesible for them. However, Libre VR bypassed it recently.
We have not recorded any public policy that regards the HTC Vive. The possible restriction of its use is mentioned in sections "Enhancement, Therapy and Treatment".
Related Technologies, Project or Scientific Research
The users can purchase their apps in SteamVR a virtual reality's counterpart of Valve's Steam.
There are two projects which are related to the HTC Vive at present, HTC Vive Business Edition and Manus VR The former is already shipped. The trackers which resembles Manus VR were announced in March 2017.
HTC announced Vive's Trackers and audio straps. They will be available for developers at 27th March 2017.
The HTC Vive wireless kit was announced at Alibaba’s “11/11” in Shenzhen, China. It should be shipped by the beginning of 2017 and the cost will be $220.33.
A software developer Drew Gottlieb introduced a project of connecting HTC Vive and Microsoft HoloLens into a shared reality. Although the concept is just prototype at the moment, it already allows to combine virtual reality and augmented reality.
There is no scientific research regarding specifically ethical issues or health risks of the HTC Vive, but certain research concerning virtual reality devices or even virtual reality in general may apply.
