HEAD-VOICE CONTROL OF COMPUTER OR OTHER OUTPUT APPARATUS

摘要

A head-actuated mouse (210) includes a tilt-axis X-Y input device, or first human input device (14), which includes either optical or non-optical sensors (12A and 12B), null compensators (53A and 53B), and null-width generators (52A and 52B, and 130A and 150A) of a signal conditioner (10). Optionally, two of the null-width generators (130A and 150A) include a rate-of-change controller (144A). In addition, the head-actuated mouse (210) includes a second human input device (214). The first human input device (14) provides a "pointing" function which may be used to move/position a cursor (218) on the monitor (220) of a computer (212). The second human input device (214) provides a "clicking" function for the head-actuated mouse (210). When a voice-recognition IC (224) is used as the second human input device (214), the resultant system becomes a head-voice control (226) for a computer (212) and other controllable devices, such as a power wheelchair (80). The interface (10) optionally includes a first tremor control (40A) and a second tremor control (40B), signal limiters (48A and 48B), signal proportioners (50A and 50B) with a proportionality adjuster (66), null-width generators (52A and 52B) with a null-width adjuster (68), an ON/OFF latch (58), a null timer (62), an overrange comparator (54), a shut-down latch (56), and selective turn signal conditioners (156, 160, and 170).
