<p>A dual axis display input device having a first axis roller (14) and a second axis roller (18) located so close that both axis rollers can be rotated simultaneously by one finger touch to simultaneously change positional information in a first and second axes. Both rollers are connected to interface electronics by a transducer. A spring-loaded momentary contact switch (44), preferably connected to rollers, provides a first switch signal. Optional second spring-loaded momentary contact switch (48) is included to provide a second switch signal. Further handheld embodiment comprises a microphone (26) able to receive audio speech and converting it to audio speech signal and forwarding it to a host device. One embodiment comprises a pair of rollers at the end of an elongated housing (10) connected to a ball (19). The combination of a dual axis display input device with the second embodiment's ball (19) at the end of the housing (10) provides a four dimension input device.</p> |
