We implemented a light-sensing function on CMOS-based multi-chip stimulator for retinal prosthesis. Using the light-sensing circuitry attached to each stimulation electrode, the flexible multi-chip stimulator is capable of image-based patterned stimulation. We verified the function of the light-controlled decision based on the light intensity measured just beside the stimulation site. We also experimentally...
We developed a CMOS LSI stimulator chip for retinal prosthesis technology with features of (1) multi-site stimulation using an on-chip stimulator, (2) light-controlled (image-based) stimulation. The retinal stimulator was configured as an array of small-sized intelligent CMOS stimulators called a ldquounit chip.rdquo We can set different conditions for each unit chip connected to a single set of 5-channel...
This study aims to establish an accessible interaction model that resembles barrier-free human communication, which is examined through the eye movement. It utilizes human communication as a social function in human-agent interaction. This has two advantages: (1) decreasing user's cognitive load to communicate with other people, (2) avoiding special training to access directly to computers. This psychological...
