An optical touchpad that may be able to provide accurate, reliable information about the position of an object in three-dimensions. The optical touchpad may enable a determination as to whether the object is engaged with the touchpad or hovering just above the touchpad. When the object is in contact with the optical touchpad, the optical touchpad may enable a determination of the force applied by the object to the optical touchpad. The optical touchpad may enable a determination of an object type of the object. These and other determinations of information related to the object may enhance the control provided by the touchpad system to the user as an electronic interface. The operation of the optical touchpad may further enable an enhanced frame rate, reduced optical noise in the optical signal(s) guided to the one or more sensors, augment the ruggedness of the optical touchpad, an enhanced form factor {e.g., thinner), and/or provide other advantages. |
