A computer mouse including a base with bottom surface for sliding across a work surface, with a retrievable tip for providing a resistance point for precision movements. At retrieved position, the tip is not touching the work surface, proving regular mouse movement. At working position, the tip is touching the work surface and creating resistance for precise movement of the mouse over the work surface.

In some embodiments, computer mouse operated with tip in braked position allows the user to make rotational movements/gestures that can be registered by computer program to invoke actions, this new type of gesture is especially important for people with disabilities that have difficulties with existing gesture like clicking button.

In some embodiments, computer mouse operated with tip in braked position allows users with hand tremor to improve cursor positioning by stopping cursor in vicinity of target, then reaching target by rotational movement.

A tool insertion structure and an electronic device are provided. The tool insertion structure includes a base, a body and an elastic element. The body includes a sleeve portion having an insertion space for a tool. The body is movable between a first position and a second position and relative to the base. The elastic element is connected to the base and the body to provide a force for moving the body from the second position to the first position. The size of the insertion space varies as the body moves between the first position and the second position.

A pen holder includes a holder to hold an electronic pen including a replaceable pen tip that contacts a screen of a display apparatus for input to the display apparatus. The pen holder further includes a pulling-out portion to pull out the pen tip, having an open end in a first direction and including a gripping portion. The gripping portion includes a first wall and a second to grip the pen tip inserted from the open end in the first direction. The first wall linearly extends in the first direction, and the second wall linearly extends in the first direction and disposed at a distance from the first wall in a second direction intersecting the first direction.

A tactile presentation panel according to the present invention includes a tactile presentation voltage generation circuit that generates a voltage signal having a first frequency to be applied to at least one first electrode located in at least a partial region on an operation surface of the tactile presentation panel, and generates a voltage signal having a second frequency different from the first frequency to be applied to at least one second electrode located in at least a partial region on the operation surface of the tactile presentation panel, a charge discharge portion that is connected to the tactile electrode and discharges charges accumulated in a conductive elastic portion, and a touch detection circuit that detects contact of the user with a tactile presentation knob.

The patent relates to securely storing an input device relative to a computing device. One example can include a housing and a trough defined in the housing and configured to receive at least a portion of an input device. This example can also include a pair of opposing levers that are contained in the trough when the trough is empty and that pivot proud out of the trough around and against the input device installed in the trough.
