The theoretical basis of DEVISE is that an efficient improvement of EV should target one of the most fundamental visuomotor functions in humans: pointing at targets with an appropriate combination of hand, head, and eyes. We claim that this function should be re-adapted and assisted in priority thanks to (1) a rehabilitation solution based on an innovative interface (developed by our group and called “smart pointing and augmentation”- SPA), and (2) a visual aid solution, based on the same pointing principles, allowing autonomous interaction with the environment. These two solutions will be developed in a unified Virtual Reality (VR) E-health framework allowing patients and vision care professionals to easily use our solutions in synergy. DEVISE will capitalise on the numerous advantages of VR for low vision patients, notably the possibility to experience complex interactive pointing behaviors. Using this VR framework, DEVISE will address three challenges:
- A scientific challenge: revisit theories about EV by experimental investigation of patient’s ability to interact through head-free pointing tasks with a VR environment.
- A medical challenge: design and test novel technologies for visual rehabilitation and visual aids where patients will be assisted by individualized head-free SPA methods to improve their visual perception. This individualization will rely on retinal imaging techniques.
- An ergonomics challenge: develop innovative human-machine interfaces and serious games, allowing patients to use SPA tools easily and playfully within a VR system. These developments will be inspired by the software tools used in the video game industry to incorporate accessibility issues that are essential for patients.
