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 split keyboard is disclosed that has wrist support members that are pivotally attached to the front of key array sections and thumb cluster sections that are pivotally attached to the key array sections on a transitional side that extends in diagonal direction from a front side of the key array section to a lateral side of the key array section.

A keyboard using temporal evaluation of timestamps. The keyboard changes the functions of keys based the temporal relation of key events on home row. Other embodiments are also described and claimed.

A push button mechanism for an endoscope includes: a first stem having a first longitudinal direction and having a first end portion connected inside a finger placement member; a second stem having a first end face in contact with a second end portion of the first stem and slidably provided along a second longitudinal direction having a predetermined angle relative to the first longitudinal direction; a switch configured to be switched by the second stem sliding in the second longitudinal direction in contact with the second end portion of the first stem moving in conjunction with the finger placement member; and an immobile member including a space in which the second end portion of the first stem is housed, and the space has a sectional shape similar to the second end portion formed in a deformed shape and prevents rotation of the first stem.

The invention relates to an input device in the form of a single-hand keyboard, comprising a substantially flat housing (1) approximately in the shape of a quadrant of a circle, in which housing a first keyboard circuit board having associated first keys (2) is accommodated, the first keys (2) lying on a first housing side (3) and being arranged along concentric circular arc segments in the manner of a fan. A second keyboard circuit board having associated second keys (4) is accommodated in the housing (1), the second keys lying on the second housing side (5) facing away from the first housing side (3), and the layout of the second keys (4) being mirror-inverted with respect to the layout of the first keys (2). Furthermore, a detection element for determining the current orientation of the input device is provided in the housing (1). The detection element activates only the keyboard circuit board facing upward and deactivates the other keyboard circuit board, depending on the orientation.

A portable data terminal including a main housing, a landscape-oriented large display screen disposed on a top front portion of the main housing and extending nearly an entire width of the main housing, a keyboard disposed on top of the main housing and rearward to the display screen, and left and right battery housings serving as ergonomic handle grips disposed on an underside of the main housing to accommodate two-handed grasping of the device, the keyboard being constructed and arranged to receive input from a pair of thumbs while corresponding hands are grasping and supporting the main housing. In an embodiment, the main housing includes a central housing portion extending downwardly on the underside of the main housing and having an extended front face for containing a scan engine/data reading mechanism and first and second cameras positioned on opposite lateral sides of the scan engine.

A robot teaching device allowing a user to operate an enable switch provided on the robot teaching device in a similar manner regardless of the user's dominant hand. A hand-held robot teaching device includes an enable switch built-in includes a main body including a holding portion that is configured to be held by one hand, and an enable switch operating section that is provided on the holding portion and is configured to be operated by a reference switching motion of a hand holding the holding portion in a reference position. The enable switch operating section includes a switching motion specifying mechanism that makes the reference switching motion in the reference position easier than another motion.
