This invention is an ergonomic computer mouse. The computer mouse body has a unique design in shape that may change the way for people to use a computer mouse. It is designed to be handheld by ring finger, little finger, and the hand part between thumb and index finger with a grip handle. A rear extrusion is smoothly curved and is designed to create a curved support area for the hand part between thumb and index finger. A trackball is confined in the body with a spherical housing and partially exposed on right side and left side of the body. The trackball is arranged near the middle of the body and above the grip handle so that thumb can reach it and operate it in its natural posture. A trackball cover is designed to separate the trackball and hand palm. Two click buttons and scroll wheel are arranged vertically on the fore edge of the body so that index finger and middle finger can naturally reach and operate them. A finger guard ring is designed to help adjusting the body's location in a hand palm with ring finger and little finger. A curved top edge and a front extrusion are designed to make the body shape look aesthetic. Two spherical extrusions on each side of the body are designed to provide 3-points support together with trackball on a flat surface. People can hold and use the mouse at any desired orientation without a flat surface and can use either right hand or left hand to operate it. It can also be used on a flat desk surface (even on a transparent flat surface) as people use a regular computer mouse. It allows people to take a comfortable desired posture to operate the computer mouse and allows people to change hand to operate it. As a result it can reduce discomfort, pain, and fatigue injury on a user's hand, arm, and shoulder when the user works on a computer with this invention.

A computer mouse has a mouse button face with at least one mouse button for operation by a finger of a user and a thumb face opposite of the mouse button face for engagement by a thumb of that user. At least one sensor is provided for detecting a mode of operation by a user. In a first detected mode of operation, a displacement operation by a user causes a user interface display of a computer system to show a movement in a direction in a displayed image. In a second detected mode of operation, the same displacement operation by a user causes the user interface display to show a different movement in a different direction in the displayed image. Also described is a mouse with a touchpad surface area partially located between mouse buttons, partially overlapping the buttons and partially in flexible hinge areas of caps of the buttons.

A position indicator includes a cylindrical case, a signal output device, a core body portion, an urging device, a substrate, a plurality of flat springs, and a conduction member. The signal output device is in the case and outputs a detection signal to a position detection device. The core body portion is provided to be freely movable inside the case along an axial direction. The urging device urges the core body portion toward one end side of the case. The substrate includes a circuit connected to the signal output device, and extends in a direction parallel with the axial direction. The flat springs have elasticity in the axial direction, protrude from the substrate toward the core body portion while making contact with the end surface. The conduction member causes the flat springs to become conductive to each other by moving to a position of contact with the flat springs.

A hand operated computer input device comprising a main body with a flat support surface for the entire palm heel is provided. The new support surface is not for the palm, metacarpals, MCP joints, proximal and intermediate finger segments, or wrist. Only a user's palm heel and finger tips touch the horizontal input device. The entire palm heel supports the weight of a users hand and arm. There is no compression of the median nerve at the wrist or in the hand.

The hand maintains a neutral position and there is no angle at the wrist. The height between the top of the palm heel support surface and the top surface of the buttons, wheels, multi-touch surface, etc. places the hand in a neutral, relaxed position.

The present invention seeks to prevent repetitive strain injury (RSI) and Carpal Tunnel Syndrome while using a horizontal or vertical hand operated computer input device.

Embodiments of the present disclosure are directed to a conically-shaped, handheld device that can be used as a computer system input/output device, a gaming system controller, a remote control for various household electronic devices, an interface to a home network, etc. Inputs through the device can be received from various buttons, switches, panels, etc. disposed along a surface of the device as well as sensors embedded within the device. Outputs can be made through speakers, displays, and other transducers also disposed along the surface of the device or embedded with therein. Furthermore, the overall shape and size of the device can be adapted to an individual user through pneumatic bladders disposed within the device.

A vertical mouse includes a base and a mouse body. The base has a vertical receiving groove. The mouse body includes a housing. The mouse body is detachably received in the vertical receiving groove, the housing leans against the vertical receiving groove, and the mouse body has a first operation mode and a second operation mode. Under the first operation mode, the mouse body is received in the base with a first orientation, and under the second operation mode, the mouse body is received in the base with a second orientation.

A mouse including a housing, an image sensing element, a lens, or a laser Doppler cursor positioning sensor; a light-transmitting hole is located where the housing is intersected with a third plane, the third plane is defined by an edge intersecting a first plane and a second plane and a halving line of an angle of the first plane and the second plane; a light source is provided and configured to emit a light beam from the light-transmitting region to the working surface, and the lens is configured to focus a reflected light of the light beam on the working surface to be transmitted to the image sensing element through the light-transmitting hole; or the laser Doppler cursor positioning sensor is configured to project a light from the light-transmitting region to the working surface, and a reflected light is also fed back to the sensor through the light-transmitting hole.
