摘要： A user input device to generate an optical navigation signal based on an edge-lit pattern. The user input device includes an optical element, a light source, a sensor array, and a navigation engine. The optical element includes a finger interface surface. At least a portion of the optical element exhibits total internal reflection (TIR). The light source provides light to the finger interface surface. The sensor array detects light reflected from the finger interface surface in response to contact between a finger and the finger interface surface. The contact between the finger and the finger interface surface disrupts the TIR and causes light to be reflected out of the optical element towards the sensor array. The navigation engine generates lateral movement information, which is indicative of lateral movement of the finger relative to the sensor array, in response to the detected light.

摘要： A light pipe for an optical navigation system. The light pipe includes a collection surface, a collimation surface, and a reflective surface. The collection surface is to accept incident light into the light pipe from a light source. The collimation surface is to collimate the light and to direct the collimated light to a navigation plane for detection by a navigation sensor. The reflective surface is between the collection surface and the collimation surface and is to reflect the light along a reflective path as the light travels within the light pipe from the collection surface to the collimation surface. The reflective surface has a curved geometry oriented substantially along the path of travel of the light through the light pipe. The curved geometry of the reflective path facilitates convergence of the light with respect to a first axis.

In one form, the optical navigation sensor also includes a light emitting diode (LED) for illuminating a small area of a surface under the sensor and generating a reflected image that is detected by the electronic chip. In a sensor having an integral LED, an integral collimating lens is included for receiving light from the LED and focusing the light from the LED on the surface to be illuminated. The collimating lens is incorporated into a lens housing surrounding the LED and protecting the LED from exposure to foreign material.
