A system for navigating a host device, including a host device, a display serving as a graphical user interface (GUI), and a keyboard with navigational control functions is disclosed. The keyboard comprises at least a frame, a plurality of keys, one or more key-top touch sensors, one or more edge touch sensors, and a keyboard communication interface. The keyboard is an all-in-one input device capable of operatively receiving text inputs, mouse cursor inputs, and gesture inputs from a user, sending them to the host device, and controlling a GUI of the host device. Advantageously, the keyboard may replace a conventional keyboard and mouse without sacrificing the individual functionality of either apparatus.

A roller wheel module includes a roller wheel, an elastic member, and an adjustment assembly. The roller wheel includes a ratchet structure and has a configuration surface. The configuration surface is divided into a blank region and a ratchet region. The ratchet structure is disposed on the configuration surface and is located in the ratchet region. The elastic member is disposed next to the roller wheel and has a first end and a second end opposite to each other. The first end of the elastic member is connected to the adjustment assembly, and the adjustment assembly drives the second end of the elastic member to move between the blank region and the ratchet region. The roller wheel module allows the user to switch between a ratchet rotating mode and a smooth rolling mode according to requirements, and allows the user to quickly scrolling and have a better touch feel.

A portable computer includes a display portion comprising a display and a base portion pivotally coupled to the display portion. The base portion may include a bottom case and a top case, formed from a dielectric material, coupled to the bottom case. The top case may include a top member defining a top surface of the base portion and a sidewall integrally formed with the top member and defining a side surface of the base portion. The portable computer may also include a sensing system including a first sensing system configured to determine a location of a touch input applied to the top surface of the base portion and a second sensing system configured to determine a force of the touch input.

Apparatus, systems, articles of manufacture, and methods are disclosed for physical keyboards with multi-display computing devices. An example keyboard includes a plurality of keys and a translucent backplate having a first side and a second side. The example keyboard also includes a coating between the first side of the backplate and the plurality of keys, the coating to pass light to illuminate the plurality of keys, and the coating to obscure the plurality keys when viewed from the second side of the backplate.

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.

An example keyboard can include: a base with a midpoint, a first end, and a second end opposite the first end; and a plurality of keys arranged on the base, wherein the plurality of keys is positioned to form a curved shape on the base such that the plurality of keys extend from the midpoint of the base towards a user as the plurality of keys extends towards the first end and the second end of the base.

A physical keyboard can be used to collect user input in a typing mode or in a tracking mode. To use a tracking mode, first movement data is detected for a hand of a user in relation to a physical keyboard at a first location. A determination is made that the first movement data is associated with a tracking movement. In response to determining that the movement type is associated with the tracking movement, a tracking mode is initiated. User input is provided based on the movement data and in accordance with the tracking mode. Contact data and non-contact data is used to determine a user intent, and a user instruction is processed based on the user intent.

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.

An electronic apparatus includes a chassis, a keyboard device, a frame including partition walls, and a fan device. At least part of the partition walls has a bottom edge surface notched to form an air flow path between the notched bottom edge surface and a top surface of the plate-shaped member, to have a communicating path through which adjacent key arrangement holes communicate. A height of the communicating path in a region not overlapping with the fan device is lower than a height of the communicating path in a region overlapping with the fan device, in a plan view of the chassis.

An electronic apparatus that comprises at least a repositioning mechanism wherein at least one of said repositioning mechanisms alternately repositions for use and disuse at least an input device such that user can transition from using at least one of said input devices to using at least another one of said input devices even while both palms remain continuously engaged to their locations.
