| 摘要 |
An optical mouse device that includes a light source and an object, such as an operator's hand or other instrument that is disposed in the path of the light energy to reflect the light energy emitted from the light source. At least one sensor unit receives the reflected light energy and generates electrical signals based on the received reflected light energy. The electrical signals may be used to control an apparatus, such as a cursor on a computer screen, operating table, or industrial machinery.
