Activities of Daily Living (ADL) Virtual Reality (VR) for Acquired Brain Injury (ABI) Upper-Limb Rehabilitation

"The virtual reality (VR) training tool simulates cooking, an activity of daily living (ADL). The layout of VR environments intentionally place ingredients, tools, and the recipe book far away from the user to require gross upper-limb physical movements. Successful step completion requires reaching to obtain ingredients or turn book pages, grabbing to hold or release objects, and chopping, scooping, stirring, and pouring motions to prepare food items. The VR tool includes three versions of varying graphical complexity: Simple, Standard, and Complex.~Complexity is controlled by stimuli count and detail level. For example, Simple features an empty room with monotone colors, basic shapes, and no extra features. In contrast, Complex resembles a fully-fledged kitchen with color patterns, textures, background details, and sounds."
