A Brown University senior thesis project focuses on inclusive design and collection of user’s sleep pattern data, reports The Brown Daily Herald.

While sleep-tracking devices exist — smartphones and Fitbits, for example — the group believed that these technologies may not monitor all aspects of sleep as seamlessly as something within the bed could. “We settled on a pillow … there’s enough cushion in there that we could put some sensors inside,” Huang said. Additionally, the pillow concept would allow them to combine different tracking devices such as accelerometers, gyroscopes and even pressure sensors.
