Abstract
Neglect affects an estimated one in four individuals who experience a stroke. Because of its association with overall stroke severity, individuals with neglect tend to have poorer prognosis for recovery. Treatment of neglect in acute stroke can yield greater recovery of a person’s ability to successfully perform activities of daily living. However, most individuals have insufficient access to effective treatments. Hemi-spatial neglect is a type of brain problem after stroke that people with this problem is living in a one-side world, which means they can only recognize one side of the object they see in their eyes, and automatically ignored the other side. Current existed treatment which is called Constraint Induced Movement Therapy (CI therapy) is to Hemi-spatial neglect is having the patient staying at hospital and repeat being forced to look at the side they tend to ignore by a doctor. This traditional treatment for hemi-spatial neglect is very tedious and a repetition of a motor practice thus has little effect on patients. Recently, game-based treatments for neglect have shown some important progress. We, as a team, designed an immersive 3D video game, which has very user-friendly interface and driven by eye gaze, in order to train them to look at the other side so that they may get a better chance to recover as normal people. This will provide direct, intensive, and implicit training of visual attention, while enabling real-time assessment of performance and feedback. The game is calibrated with The Eye Tribe Eye Tracker as a monitor to the movement of eyeballs and based on 3D modeling technology: Autodesk Maya with the assistance of Adobe Photoshop for creating game assets, and imported them to the Unreal Game Engine 4.0 and program the game with C++ and BluePrint visualized language.
