A precision-controlled research platform for generating visual flicker and auditory modulation.
The Asteria project was designed to support experimental research on 40Hz photo-acoustic therapy, which has been proposed as a non-pharmaceutical alternative for Alzheimer’s disease treatment by MIT’s Tsai Lab. Asteria also enables the exploration of UX opportunities and challenges among elderly users.Originally a student project from the 2019 Interactive Technology Design course at TU Delft's IDE faculty, it was iterated upon by Vibe Research Labs with the intention of collecting empirical aesthetic data.
In its current form, Asteria consists of modified VR goggles and a physical slider interface. LED rings are embedded in the goggles and surround the user's visual field when worn. The brightness, hue and duty cycle of the LEDs can be controlled by the sliders, the values of which are recorded in real-time using a Python script and saved to a database.
Further research is planned using the Asteria system to investigate the effects of combined light and audio frequency-based therapies.
