“…The computing component collects sensor data and determines what is displayed on the screen [20]. During physical rehabilitation, the patient's body shape change and position movement must be captured by the motion tracking sensor and simultaneously transmitted to the virtual object in VR [21]. Sensors that track patient motion must have accessories with motion visualization functions, including mice, joystick, depth-sensing cameras [22], electromagnetic sensors [23], inertial sensors, bending sensors, and data gloves.…”

The present work investigates the application of virtual reality (VR) technology to neurorehabilitation. By consulting a wealth of data, the advantages of VR in neurorehabilitation are introduced, followed by the application status of VR in the rehabilitation of stroke patients, Parkinson's patients, mental and psychological diseases. Besides, many research experiments on the application of VR technology in rehabilitation medicine at the present stage are investigated. The results indicate that compared with traditional balance training, the VR-based neurological rehabilitation training method can more effectively ease the tilt degree and strengthen the trunk control ability and balance function of patients with post-stroke tilt syndrome. When the effect of traditional rehabilitation training on the gait and balance of Parkinson's patients is not good enough, VR-based rehabilitation training can at least be used as an alternative therapy. Moreover, VR games have made great breakthroughs in promoting limb rehabilitation and brain injury rehabilitation, which is of incredible benefit to those with motor and activity disorders. It is also beneficial to the treatment and recovery of mental disorders of patients with nerve injury. Although VR still has limitations such as high cost and technical breakthrough bottleneck, it has great advantages in relieving pain, enhancing interest, and recovering patients' mental health in neurological rehabilitation training.

“…shaking hands). As such, researchers have developed a variety of target disambiguation techniques that requires additional manual steps for final selection [5,23,35,77] or that apply contextual information or heuristics for implicit disambiguation [23,24,60,68]. However, while these techniques help users perform difficult selections, many assume a stable signal to disambiguate target candidates.…”

“…Further research needs to be done to evaluate the techniques in more natural settings. Occlusion is interesting to investigate as targets are closely placed together, and occlusion lessens the effective target width making interaction more difficult, especially with noisy data [66,77]. The impact of data noise on interaction has to be further investigated within applications and natural environments beyond controlled lab environments.…”

Fig. 1. The Weighted Pointer provides stable gaze-based pointing interaction irrespective of gaze signal quality via fallback modalities.The techniques detect the eye tracking error level and determines the relative weighting to assign between gaze and the fallback modality. A: The pointer direction (red) is aligned with gaze (orange) when the gaze signal is stable. B: The pointer relies on both gaze and the fallback modality (e.g., head direction, green) if the gaze signal deteriorates. C: The pointer fully relies on the fallback modality if gaze is deemed to be unusable for interaction.
