Abstract

A wireless handheld electronic device configured to send and receive text messages. A microprocessor for receiving, processing and outputting data is located within the handheld device. A display screen in data-communication with the microprocessor presents information for user observation based upon data output from the microprocessor. A sensor is provided within the handheld device that detects the attitude of the device as held by the user. The sensor communicates data that is indicative of the detected attitude of the device to the microprocessor. The microprocessor is further enable to disable a user input device when the detected attitude of the device matches a predetermined attitude criteria.
