This demonstration showcases the XR extension of the Eligence platform, a cognitive training application for individuals at risk of or in the early stages of dementia and Alzheimer’s disease. The extension introduces existing 2D Eligence games, reimagined and redesigned in augmented and virtual reality environments, as well as holographic telepresence of the beneficiaries’ assisting health professionals - developed as part of the European SPIRIT project. This demo version of the Eligence XR app focuses on the immersive games themselves, their role in promoting cognitive training through embodied interaction, and the UX comparison of the extension VS their 2D counterparts. 
The cognitive games featured in this demo have been designed with the assistance and monitoring of neuropsychologists and healthcare professionals of Alzheimer Athens Association (AA) to respond to the needs of people with cognitive vulnerabilities, especially older adults. Two different games have been adapted so far into interactive and engaging XR experiences. The first one is a “pop the balloons” game exercising attention and visuo-spatial awareness of the users, while lightly training their arms’ mobility, whereas the second one simulates a supermarket where the player needs to physically (and virtually) navigate and shop, while trying to remember what items were on the list that appeared at the beginning of the game. These scenarios – in AR and VR accordingly - are structured to train memory, attention, executive functions and motor coordination, as well as entertain the users while doing so.
While this demo emphasizes the value of the VR cognitive training suite, the broader Eligence XR system incorporates an experimental module for holographic telepresence , powered by the SPIRIT platform. This feature enables HPs to appear as volumetric video streams within the same virtual environment, offering real-time guidance, presence, and emotional support.
