초록 ▼

A optical input device which can determine the location of a stylus in a field with only a single emitter and a single detector. A fiber-optic bundle is used to transmit energy from the emitter to the vertical and horizontal output sides of a bezel. The fiber-optic bundle returns energy from the input vertical and horizontal sides of the bezel to the detector. The bezel is covered by LCD masks which block energy transmission through the bezel. A multiplexor scans the LCD masks to allow a beam of energy to scan across the vertical and horizontal fields of the device. The location of a stylus is located by detecting an interrupted beam.

대표청구항 ▼

An optical input device for detecting and communicating to a computer the location of a stylus within a predetermined field, comprising: a frame; the frame further comprising a first vertical side, a second vertical side, a first horizontal side, and a second horizontal side; a single energy emitter; a single energy detector; a fiber optic bundle; the fiber optic bundle having a first energy path connected at one end to the energy emitter such that energy from the energy emitter enters the first energy path and travels through the fibers of the energy path; the first energy path connected at the other end to the first horizontal side and the first vertical side such that the first horizontal side and the first vertical side do not obstruct the energy when the energy exits the first energy path; the fibers in the first energy path further arranged such that energy exiting the first energy path is transmitted from a wide area of the first horizontal side and the first vertical side substantially perpendicular to the surfaces of the first horizontal side and the first vertical side, and toward the second horizontal side and the second vertical side respectively; the fiber optic bundle having a second energy path connected at one end to the second horizontal side and the second vertical side, the fibers in the second energy path arranged such that energy received along a wide area of the second horizontal side from the first horizontal side, and energy received along a wide area of the second vertical side from the first vertical side enter the fibers; the second energy path connected at the other end to the energy detector such that energy traveling through the second energy path is detected by the energy detector; the energy detector further having means to provide a signal to the computer indicating the presence or absence of energy; first and second vertical LCD masks attached respectively to the first and second vertical sides of the frame, the masks arranged such that they lie in the path of energy transmitted from the first vertical side to the second vertical side; first and second horizontal LCD masks attached respectively to the first and second horizontal sides of the frame, the masks arranged such that they lie in the path of energy transmitted from the first horizontal side to the second horizontal side; a multiplexor having means to receive control signals from the computer; the multiplexor having means to synchronously scan the first and second vertical LCD masks such that only a narrow beam of energy can travel from the first vertical side to the second vertical side at any point in time; the multiplexor having means to synchronously scan the first and second horizontal LCD masks such that only a narrow beam of energy can travel from the first horizontal side to the second horizontal side at any point in time; the multiplexor having means to mask all first and second horizontal LCD masks when the first and second vertical LCD masks are scanned, and mask all first and second vertical LCD masks when the first and second horizontal LCD masks are scanned.
