Haptic actuators disposed under the fixed keys provides feedback to an end user when an input is sensed at a fixed key.

A haptic keyboard of an information handling system may comprise a coversheet to identify an extended action key of the haptic keyboard, a support layer, a contact foil, and piezoelectric elements placed between the contact foil and support layer to receive an applied mechanical stress at the extended action key and generate an electric actuation signal. A controller may receive the electric actuation signal from a piezoelectric element placed under the mechanical stress, via the contact foil, and determine the level of mechanical stress applied to the piezoelectric element from the electric actuation signal to select an alphanumeric character from a plurality of alphanumeric characters based on the mechanical stress level applied to the extended action key and provide a response haptic feedback control signal to cause the piezoelectric element to generate haptic feedback.

A control device is configured to output a detection signal indicating that an instruction input is performed through the movable part in a case where a variation in the electrostatic capacitance exceeds a first threshold value and a first displacement amount that is a displacement amount of the movable part from an initial position thereof exceeds a second threshold value.

A multi-functional human interface device includes a control unit and a first multi-functional input button. The first multi-functional input button includes a cover unit configured to receive a touch input of a user's finger, an electrode unit including a transmitter and a receiver to form an electric field, an elastic unit configured to move from a first height to a second height when a first pressure is applied from the cover unit and configured to move back to the first height when the first pressure from the cover unit is released, and a switch unit configured to generate an electric signal representing an input of a predetermined letter.

A light guide plate and a backlight module adapted to an illuminated keyboard are provided. The light guide plate includes a single-key light guide region. The single-key light guide region corresponds to a single key. Four diagonal regions of the single-key light guide region has a plurality of microstructures. The area sum of the plurality of microstructures is smaller than the area sum of the four diagonal regions of the single-key light guide region. Through the area control of a plurality of microstructures, the plurality of microstructures of a plurality of keys guide the light to make the brightness of each of the keys is even.

Provided is an information output apparatus including one or more information output units, wherein each information output unit includes a coil arranged to be connected to a power source, such that a current flows in the coil; a base unit configured to accommodate the coil; and a driving indicator, which is arranged in the base unit to be apart from and close to the coil to be driven by a current flowing in the coil and is configured to move in a first direction toward the coil and a direction opposite thereto to rotate while being connected to the base unit and to move in a second direction crossing the first direction to be recognized by a user.

A mouse device includes a casing, at least one aspheric light guide plate and a light source. The casing includes an upper cover and a base. The upper cover includes at least one lateral surface. The aspheric light guide plate is installed on the lateral surface of the upper cover. Each aspheric light guide plate includes a light input surface and a light output surface. The light input surface and the light output surface are not in parallel with each other. The light output surface is aligned with the corresponding lateral surface of the casing. The light source is installed on the light input surface of at least one aspheric light guide plate. The light source emits light beams. After the light beams are inputted into the aspheric light guide plate through the light input surface, the light beams are outputted from the light output surface.

An example apparatus includes a first flexible portion connected to a second flexible portion. The first flexible portion includes a keyboard having a set of input keys disposed thereon and circuitry coupled to the set of input keys, the first flexible portion is to couple to a portable computing device proximal to a display side of the portable computing device. The second flexible portion has a plurality of fasteners to couple to a kickstand of the portable computing device, the first and second flexible portion to provide an opposing force there between while the kickstand is disposed at one of a plurality of variable support angles.

Systems and methods provide haptic feedback at locations of a keyboard palm rest during operation of a software program, such as a video game. During game play, a haptic event, such as an explosion, is detected within the game. A magnitude of the event and a direction of the event from a reference location in the game, such as an avatar's location, are determined. Haptic feedback locations on the palm rest are selected based on the magnitude of the event and the direction of the event from the reference location. Mechanical and thermal haptic feedback are generated at the selected locations of the palm rest, where the strength and timing of the feedback at each location are selected based on the magnitude and direction information for the event. Embodiments thus provide multi-dimensional haptic feedback that relates positional awareness to a user of events occurring within a video game.
