Virtual reality technology

Virtual reality (VR) is an immersive technology that uses headsets and sensors to immerse users in simulated environments. KineQuantum is using this technology to revolutionize the field of physiotherapy. Our devices, KineQuantum Classic and KineQuantum Liberty, incorporate advanced technologies to offer effective, customized therapeutic solutions.

3d vision of the VR headset

The virtual reality headset is equipped with high-definition screens placed in front of the user's eyes. This enables the user to perceive the image in all three dimensions. With slightly offset images on each screen, this reproduces our binocular vision. In effect, our eyes each perceive two different images, and it's our brains that combine them into a single 3D image.

Wide field of view

A person can see what's around them over an area of 200° to 200°. Each of our eyes has its own field of view (FOV). At the point where the FOVs of our two eyes meet is our binocular stereoscopic field of vision, approximately 114°, in which we actually see in 3D. Virtual reality should enable us to approach this effect.

Technical aspects of Virtual Reality

Virtual reality requires several essential elements to deliver a successful immersive experience. Quality hardware, such as a high-end virtual reality headset and a powerful computer, is essential. However, this is not enough. Advanced technical know-how is also crucial: virtual reality software developers need to master complex concepts to guarantee optimal immersion.

Technical hardware components

A high-end VR headset

For VR headsets, several technical parameters are essential. The optical lenses, positioned in front of the eyes, must offer a wide field of view (FOV) and a comfortable experience. The screen, located behind the lenses, must be of optimum size and resolution to guarantee high angular resolution, crucial for visual realism. It must also be comfortable and ergonomic.

Motion sensors

The virtual reality system also relies on motion sensors. Sensors such as accelerometers, gyroscopes and magnetometers are integrated into the headset. These track the user's movements in space, detecting and adjusting images in real time according to the user's actions. They can be located on the headset, the controllers or in the room, and their number and strategic location are crucial to optimal immersion.

Controllers for interaction

VR controllers are essential for interacting with the virtual environment. Equipped with motion sensors and offering haptic feedback, they enhance immersion by simulating tactile sensations through vibrations. Although some systems use cameras to detect hand movements without controllers, this approach has real limitations.

A powerful computer for a smooth experience

A powerful computer enables a fluid experience by reacting almost in real time to the user's movements. This fast reaction time ensures user comfort and smooth graphics rendering. For this, a high-performance graphics card is essential. By minimizing the time lag between the user's movement and the computer's reaction, this guarantees a latency-free image in the VR headset.

Designers' technical know-how

VR software generates virtual environments and interactive scenarios. These programs use complex algorithms to deliver a realistic, responsive experience. Movement is crucial to a convincing experience, and the environment must adapt to the user's movements. However, mastering the technique is not enough; you need real know-how to develop correctly in virtual reality, with specialized skills and tools.

Calibrated movements

Excessively sudden or large movements of the images can cause a feeling of unease. Motion mechanisms and camera controls must be carefully planned.

Playful experiences

It's the playful dimension that allows the user to concentrate on the game rather than on his or her movements. This is essential, especially for rehabilitation.


It's important to put yourself in the user's shoes. We need to develop games that are simple, well-explained and suitable for a wide audience. Thorough testing is crucial to ensure that the game is suitable for all users.


The absence of interactivity damages the experience. Providing visual, auditory and haptic feedback engages users and helps them interact with the virtual world. This reinforces the sense of presence in the virtual world.

Enhanced performance

Performance optimization is essential for smooth VR environments. Low frame rates or crashes can ruin the experience. It's all about smooth, consistent performance.

User-friendly interface

The software that launches VR must offer a simple interface for users. It's important to avoid an overly complex interface, while offering maximum possibilities with intuitive navigation.

The 3 key stages in virtual reality

  1. Image creation: VR software on the computer produces the necessary images

  2. Displaying the images: These images are projected into the VR headset, creating an illusion of depth.

  3. Movement tracking: The user's movements are precisely tracked by the headset and controllers, enabling real-time adaptation of the projected images.
