Apparatus and method for expanded touch sensitive actuation of a user interface button

摘要

A user interface apparatus and method are provided for gloved and non-gloved touch sensitive button actuation. A user interface (100) embodied as a body wearable harness (104) provides a touch button control system having an activation button (120) and functional touch sensitive control buttons (108, 110, 140). The activation button (120) has a capacitive touch element (130) associated therewith that determines gloved or non-gloved operation based on a capacitive measurement taken in response to a finger input to the button. A plurality of control buttons (108, 110, and 140) are automatically assigned increased sensitivity levels in response to detected gloved mode operation in accordance with the measurement. The increased sensitivity levels allow various radio functions to be accessed by a gloved finger input during gloved mode operation with increased reliability. Additional control button identification can be added through the addition of vibrational alerts. Display and screen type control buttons can further be combined into larger and fewer buttons for ease of gloved landing.
