Speech-Based Virtual Assistant for Treatment of Alzheimer Disease Patient Using Virtual Reality Environment (VRE)

One of the major diseases that affect the elderly is the Alzheimer disease (AD) which is characterized by partial or complete loss of memory. Early detection and early treatment could help in managing the Alzheimer disease on potential patients. This paper introduces a virtual reality assistant (VRA) into a virtual environment. The VRA gives commands to the user through a wearable immersive virtual reality Google. The patients are made to complete varying levels of tasks of which a deviation from the normal results of the task was an indicator of a potential sufferer of the AD. The VR used Natural Language in Artificial Intelligence for communicating, the tasks were designed with Unity Game Engine and VR cardboard Google was used. The result obtained showed that patients found the Virtual Reality Assistant in the simulation helpful.
