The System for Tactile Reception of Advanced Patterns (STRAP) is capable of displaying complex information through tactile actuators on a user's torso. Non-verbal communication requirements from a Military Operations in Urban Terrain (MOUT) task and tactile design guidelines resulted greater than 60 distinct tactile symbols for communication and a context free grammar. This empirical evaluation is the first step in validating the STRAP system as a complement to traditional communication methods such as military hand and arm signals and radio. Nine participants were trained on the entire tactile language to a 90% criterion and were asked to utilize a small subset of the vocabulary while completing room clearing tasks using a virtual desktop simulation. The results show no significant difference in room clearing performance when haptic versus verbal communications were provided, indicating that the STRAP system shows promise as a complementary communication device. Improvements to both the tactile display and symbols are discussed as a means to improve recognition of haptic commands and overall system utility. |
