A key for a keyboard includes a keycap having a top surface configured to be contacted for pressing the key down, and having a bottom. The keycap is substantially transparent. An intermediate layer is coupled to the bottom of the keycap. The intermediate layer is translucent and includes a top and a bottom. The top of the intermediate layer faces the bottom of the keycap. A character layer is positioned between the bottom of the keycap and the top of the intermediate layer. A resilient member is coupled to the bottom of the intermediate layer. The resilient member is translucent and is configured to direct light through the intermediate layer, through the character layer, and out from the keycap. The character layer is configured to be lighted for viewing through the keycap.

A method includes placing an input device in a passive mode of operation and periodically monitoring a displacement sensor of the input device, receiving an indication of displacement from the displacement sensor, and placing the input device in an active mode of operation characterized by a power consumption level. The method also includes determining a passing of a predetermined time period since receiving the indication of displacement, placing the input device in a second active mode of operation characterized by a second power consumption level less than the power consumption level, and periodically monitoring one or more of a plurality of touch sensors. The method further includes receiving an indication of input from the one or more of the plurality of touch sensors and placing the input device in the active mode of operation.

A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.

An optical displacement system for an input device of a host device includes a substrate; an aperture; a light source and a sensor chip attached to the substrate, an illumination optics to direct the light emitted by the light source to a surface of an object. The sensor chip is configured to receive at least part of the light emitted by the light source after the light has been scattered/reflected on the surface of the object.

An input device includes a housing for supporting a user's hand and a displacement sensor, mounted in the housing, for providing a displacement signal. The input device also includes a first portion of the housing operable to receive a first digit of the user and a first solid-state touch sensor disposed in the first portion and operable to detect movement of the first digit along the first portion. The input device further includes a second portion on the housing operable to receive a second digit of the user and a second solid-state touch sensor disposed in the second portion and operable to detect movement of the second digit along the second portion.

A control device includes a case having a bottom surface that has a front portion and a back portion; and a first friction pad and a second friction pad disposed on the front portion of the bottom surface. The first and second friction pads are configured to detect pressure from a user hand to power-up the control device. The first and second friction pads are also configured to detect the absence of the user hand and place the control device in a sleep mode based on the detection of the absence of the user hand.
摘要:
A method of reducing the power consumption of an input device includes operating the input device at a first power level, detecting the presence of a touch object on a touch surface of the input device, determining that the presence of the touch object on the touch surface is static for a predetermined period of time, operating the input device at a second power level, maintaining the input device at the second power level, determining that the presence of the touch object on the touch surface is not static, and operating the input device at the first power level. In some cases, the touch object is a finger. The touch object is static if the touch object's position on the touch surface remains within a predetermined region, where the predetermined region is an area centered around the presence of the touch object on the touch surface.

A method of calibration including powering up an input device that includes a touch sensor and placing the touch sensor in a normal mode of operation. The input device scans the touch sensor to detect a user input data and determines whether the user input is detected within a predetermined time period. If no user input is received during the predetermined time period, the method includes placing the touch sensor in a calibration mode of operation, performing a calibration process for the touch sensor, and returning the touch sensor to the normal mode of operation. Typically, the predetermined time period is greater than or equal to 30 seconds. In certain embodiments, the calibration process is performed a single time after powering up the input device. In some embodiments, the method further includes detecting a user input on one or more additional sensors within the predetermined time period.
