First Claim
1. A system comprising:
- a stylus comprising;
a housing having a first end to provide physical contact with a touch screen of a personal digital assistant;
a microphone to detect speech and to output electronic voice signals; and
a transmitter located in the housing to transmit the electronic voice signals from the microphone to either a personal computer or the personal digital assistant;
the personal computer (PC) having a processor, speech recognition software to instruct the processor to translate the electronic voice signals into translated voice data, a wireless receiver to receive the electronic voice signals from the transmitter, and a wireless transmitter to transmit the translated voice data; and
the personal digital assistant (PDA) having a touch screen display to enter information in response to physical contact and to display the translated voice data, the PDA further comprising a wireless receiver to receive the transmitted translated voice data from the personal computer and to receive electronic voice signals from the stylus.

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 containsa processor to translate received voice signals, the stylus transmits directly to the PDA, and the PDA translates the received voice signals.
