The Effects of Site Configuration on a Tactile Information Display for the Human Head
Abstract
This research investigated the feasibility of using a tactile display to transmit information via the scalp. The purpose of the study was to compare performance for various stimulus site configurations. The first phase of the study investigated the number of sites that could be reliably detected and identified for the front section and the rear section of the scalp. Also during this phase, a multi-position array condition was investigated to determine target identification performance at twelve dispersed sites on the head. The second phase of the study determined whether target identification was possible under conditions of high mental work-load. During this phase, the target identification task was conducted while performing the Criterion Task SET (CTS) Memory Search and Unstable Tracking dual-task to simulate the memory and motor output tasks encountered in a flying situation. Performance on the CTS dual-task declined significantly when performed with the target identification task.
