Virtual Reality games are those 3D images or worlds which a person actually goes into and interacts with. In order to play such a game, one requires a headset which can record his/her movements and activities and one also requires some kind of motion controls like a controller or gloves that permit moving.
One of the first VR games to break out was Beat Saber, in which players are transformed into sabre-waving dancers slicing through colour coded blocks to a music beat.
Immersive Experience
Virtual reality headsets, on the other hand, completely shut out the real world and plop a digital scene in front of you. Immersive VR needs a headset, hand controllers and a computer to run the simulation.
The first attempts at immersive technology appeared in the early 1800s in the form of stereoscopes, which showed almost-identical images to each of a user’s eyes, thereby creating a 3D effect with closed optics. 1957 was the first time that immersive VR was available to the public in any substantial amount and with any sort of enjoyment, in an invention called the Sensorama by Morton Heilig (the Hopper display name was likely an homage to him). Heilig’s cinematic experience came equipped with speakers, fans, and smell generators to further immerse the user.
Aside from gaming, virtual reality (VR) could be extremely useful for training people – firefighters, pilots, astronauts, even police – for real-world situations while also saving money on travel costs. Meetings can take place virtually, work days are shortened, and we’re increasingly interacting with employers and peers face‑to‑face in ways that keep the collegiality intact and hone our social side. In retail, capabilities such as ‘try-outs’ can get rid of buyer’s remorse entirely.
Exergames
As such, IVR exergames have been developed to encourage PA and promote healthy behaviour change. Nonetheless, user feedback from numerous studies highlight that VR game use leads to physical discomfort, fatigue and/or boredom.
Such gamification features are effective at enhancing enjoyment during VR exergaming sessions, giving participants rewards for their actions (eg, levels, challenges, points, badges) and making the immersive environment more stimulating for persons living with dementia/MCI.
The human-centred design approach that co-created the interactive VR exergame Seas the Day for end users with dementia living with mild cognitive impairment (MCI) as core end users is described in this paper. This approach demonstrates the added value of participatory design to ensure that the game is appropriate and useful in light of the complex needs, preferences and motivators of this often-overlooked end-user group and can be achieved within a short timeframe.
Visuals
V R equipment is a headset that presents screns (one for each eye) in front of your eyes. Headsets can connect with a device (like a video game console), a more advanced smartphones or a powerful personal computer/laptop that allows it to run content fluently.
VR operates in a 3D space that is difficult to reproduce on a flat image by monitor or projector. It’s natural, then, that the technology be deployed in applications far beyond gaming: in retail and real estate, for instance – customers could preview clothes, interior designs, and hairstyles – or by working multimedia designers looking to push boundaries of self-expression. It’s also commonly used by architects to both illustrate their detailed plans and visualise massing and spatial relationships long before the construction of a building begins.
Audio
But generally speaking, effective audio will help to effectively finish off the VR experience. Audio designers have to consider what sonic cues can best correspond to visual stimuli. Cross-modal associations cause input in multiple sensory pathways all at once, which increases the effect of the inputs.
The most popular audio format for VR remains Ambisonic, a technique that combines two-dimensional left-to-right stereo panning, with up-and-down and front-to-back panning; the two extra spatial dimensions help to place sounds more accurately into virtual spaces.
Spatial audio can also mimic the attenuation of sound – where the listener loses sounds that are far away – and other effects of distance and environment, so the participant can orient himself in regard to the direction of an incoming threat or effect. He or she can hear the buzzing of a bee approaching, or the splitting of wood hundreds of metres away. It’s usually a good idea in VR to do everything you can to make things seem real. There is virtually no commercial VR game from recent times that does not use directional audio to create additional engagement and excitement – as many users of the popular Metaverse smash-hit Beat Saber can attest.
Controls
Through interacting with an environment in VR , embracing a three-dimensional image space with one’s hand by putting on a headset and grasping a button-laden controller, and indeed picking up, throwing, pointing or even bending over to squat for a closer look, wearing a headset one can initiate – not merely ‘experience’ – an open world on their own.
It is also applicable to business scenarios, such as visiting the Great Barrier Reef without taking a flight to the real location of the Great Barrier Reef. Real estate can be sold using VR to take clients virtually inside a location that the client is considering to rent or buy.
The technology might not be as immersive and Matrix-style as I’d like it to be, but it can be very good – and can be a lot of fun. The fidelity of the headset, camera and controller generally results in a better experience than something lower quality. Some control techniques are simple – waving your arms to grab; others require special hardware and offer more precision and flexibility.
