This invention provides novel keyboards comprising keys disposed such that they minimize the distance a finger typically must travel to effect a keystroke and the force that is applied to effect a keystroke. Accordingly the keyboards require less arm and finger movement to and thereby reduce the likelihood of an operator developing a repetitive stress injury (RSI). In one embodiment the keyboards comprise a plurality of keys disposed such that the alphanumeric keys form a continuous key array defining a key array surface having at least two concave regions wherein a plurality of keys present irregular and/or non-rectilinear striking faces.

A conventional mouse and keyboard poses great load on the user's finger and hands at key operation, and the material used for its surface is rigid. An input device which can reduce the load on the user's finger, and gives soft touch by avoiding abrupt change in downward pressure at key operation. The input device includes elastic material on the surface, a camera to image the back surface of a key when the key is pressed, an image processor which determines finger position from the image, and an output which generates a signal according to the finger position. By using this input device, the user can carry out operations similar to those achieved by a mouse and keyboard for a computer.

An ergonomic keyboard. The keyboard includes a main body and first, second and third key groups disposed thereon. The third key group is arranged between the first key group and the second key group. The top surfaces of the keys of the first key group and the second key group are inclined to the third key group by a first angle, such that the keyboard can be more ergonomically sound.

The present invention relates to a device and method for measuring force, primarily due to fatigue. In one embodiment, a finger fatigue measuring system is provided which measures the force output from fingers while the fingers are repetitively generating forces as they strike a keyboard. Force profiles of the fingers are generated from the measurements and evaluated for fatigue. The system can be used clinically to evaluate patients, to ascertain the effectiveness of clinical intervention, pre-employment screening, to assist in minimizing the incidence of repetitive stress injuries at the keyboard, mouse, joystick, and to monitor effectiveness of various finger strengthening systems. The system can also be used in a variety of different applications adapted for measuring forces produced during performance of repetitive motions.
摘要:
An apparatus includes a support surface and a moving mechanism for automatically varying the orientation of the support surface in a predetermined manner over time to reduce or eliminate the likelihood of repetitive stress injury as a result of performing repetitive tasks on or otherwise using the support surface. By varying the orientation of the support surface, e.g., by moving and/or rotating the support surface over time, repetitive tasks performed on the support surface are modified at least subtly to reduce the repetitiveness of the individual motions performed by an operator.
摘要:
A method of user command or data acquisition in a processing system that allows for analysis of human hand and finger motions. The activities are then interpreted as operations on a physically non-existent input device. The resulting optical user/computer interface complements the visual screen-to-user path with a hand-to-image data acquisition link from the user to the processor unit. It allows for the emulation of different types of manually operated input devices (mouse, keyboard, etc.). Mechanical input units can be replaced by virtual devices, optimized for the current application and for the user's physiology. The speed, simplicity and avoidance of ambiguity of manual data input will be maintained. Sensing of finger motions can generate feedback to reduce the hazard of repetitive strain injury (RSI) syndrome.
摘要:
The keys operated by the Middle Fingers in the Second Nearest Row and the Fourth Nearest Row of the Alpha-Numeric Core, i.e. QWERTY D K 3 and 8, and the center key on the Number Pad are provided with hand positioning structures.Hand positioning with the Middle Fingers is based on the anatomical structure and bio-mechanical functioning of the arms, wrists, hands and fingers, and the hand positioning structures function by the neuro-sensory process of 2-point discrimination.With minimal practice, use of the hand positioning structures quickly functions at a subconscious reflex level.The hand positioning structures enable the operator to maintain visual focus and concentration on the text or display screen, and thereby eliminates unnecessary eye movement and text-reading errors due to eye movement.The structures and methods enable eliminating Home Row, and thereby eliminates awkward movements and contortions and eliminates the errors resulting from awkward movements and contortions.The structures and methods enable doing numbers with the hands positioned on the Number Row, rather than from Home Row, which also eliminates awkward movements and contortions, and improves speed, accuracy and efficiency in doing numbers.The hand positioning structures provide bio-mechanical balance and symmetry for the fingers and hands; improves keyboard operation by increasing operating speed, accuracy, efficiency, mobility, flexibility, fluidity of movement, and productivity; reduces operator mental, emotional, visual, and neuro-muscular stress and fatigue; and facilitates learning how to operate a keyboard. The cost of the structure is nominal; no employee retraining expense is required.

摘要:
A device is provided. The device includes a first T-shaped structure defined via a first leg and a first platform. The device further includes a key cap with an interior open chamber. The cap is mounted onto the first structure such that the chamber contains the first platform. The device also includes a second T-shaped structure defined via a second leg and a second platform. The first leg vertically moves within the second leg such that the cap travels between a non-pressed position and a pressed position. The cap is raised above the second platform in the non-pressed position. The cap is in contact with the second platform in the pressed position.
