Soldier-Based Assessment of a Dual-Row Tactor Display during Simultaneous Navigational and Robot-Monitoring Tasks

Abstract

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing the burden, to Department of Defense, Washington Headquarters Services, Directorate for Information Operations and Reports (0704-0188),

Encoding of spatial patterns using electrotactile stimulation via a multi‐pad electrode placed on the torso

“…Several patterns can be constructed with only a few spatially arranged pads, and thus, many messages can be conveyed to the user. 1,14,[27][28][29] Despite the large surface of the skin, the most sensitive areas (e.g., hands, inner portion of the legs, or face) are usually impractical for conveying haptic information. 30 In recent years, wearable tactile devices placed on the torso have gained attention.…”

“…Each message can be associated with a specific “shape” (e.g., horizontal or vertical line) produced by activating the corresponding subset of pads in the matrix (e.g., first row or first column of pads). Several patterns can be constructed with only a few spatially arranged pads, and thus, many messages can be conveyed to the user 1,14,27–29 .
