High-Resolution Feedback using Tactile Semaphores

In this paper, a novel tactile communication device for the neck is presented. This device relies on a one dimensional array of actuators and uses tactile semaphores to convey information received wirelessly from a mobile device, computer, or game console to the subject wearing the device. Tactile semaphores are tactile patterns generated by multiple actuators on the neck. The neck is unique in that it offers an intuitive one-to-one tactile correspondence between directions in the horizontal plane and locations on its periphery. This device is capable of conveying bearings with an angular resolution better than 20° and ranges with nearly 10 levels of distance, making it accurate enough for most gaming and navigation applications. Tactile semaphores may be used to mimic real-world experiences and to enhance immersion in a gaming or simulation environment. In-world experiences such as acceleration, fall, impact, or game-related sensation such as boost, gradual loss of health, win, and loss may also be conveyed through the use of dynamic semaphores called marquee patterns. Other applications of this device are also presented.
