Abstract: Systems and methods for actuating a tactile stimulation in response to detecting a specific event associated with exposure to a particular environmental or physiological condition are described herein. A tactile stimulation device, according to one of several implementations, comprises a sensing layer, an actuating layer, and an adhesive layer. The sensing layer, which is sensitive to exposure to a particular condition, is configured to sense when a specific event associated with exposure to the particular condition occurs. The actuating layer is configured to provide a tactile stimulation to a human subject when the specific event occurs. The adhesive layer is configured to affix the sensing layer and actuating layer with respect to a surface portion of the skin of the human subject such that the human subject can sense the tactile stimulation provided by the actuating layer. The sensing layer, actuating layer, and adhesive layer can be bonded together to form a relatively flat structure.

Abstract: An improved interface control advantageously may be operated by one hand. A thumbpiece is slidably disposed within a longitudinal arm member which moves in an arcuate path. Placing his or her thumb in the thumbpiece, a user controls the horizontal positioning of a cursor by moving the arm member along the arcuate path. Vertical positioning of the cursor is controlled by sliding the thumbpiece along the length of the arm member. Trigger functions are implemented by exerting a downward force on the thumbpiece. Since the downward force used to implement the trigger function is orthogonal to motions used to control positioning of the cursor irrespective of the particular positions of the arm member and thumbpiece, the disclosed interface control prevents a user from inadvertently altering the positioning of the cursor during implementation of the trigger function.
