Abstract
A mobile personal digital assistant (PDA) allows a user to enter information using both a touch screen and voice commands with a stylus. The stylus includes a microphone positioned at one end, and a transmitter for transmitting received voice signals to either a personal computer (PC) or the PDA. In one embodiment, a wireless stylus also includes a power supply and an activation control switch. The PC is used to translate the voice signals into translated voice data which is transmitted to the PDA for storage and display. If the user and the PDA are located remotely from the receiving PC, voice signals are stored in the PDA until a later time when the PC can translate the received voice signals. Where the PDA contains a processor to translate received voice signals, the stylus transmits directly to the PDA, and the PDA translates the received voice signals.
