Consideration of Electrode Placement to Improve Presentation Resolution of Phosphenes

抄録

Hands-free walking support tools for visually impaired people have been needed without interfering with other senses. Our study focuses on phosphene, which enables hands-free support for visually impaired people using visual information. Previous studies have reported that changing the position of electrodes placed on the face can change the presentation position of phosphenes. However, there is a limitation of the facial surface area. It is necessary to devise a combination of electrode arrangements to increase the resolution of the phosphene presentation. Therefore, this paper discusses how much the current is blocked and how the phosphene is presented at the intended location when the electrode placement across the nose is used.
