An interface method and apparatus using video images of hand gestures. A video signal having a frame image containing regions is input to a processor. A plurality of regions in the frame are defined and screened to locate an image of a hand in one of the regions. The hand image is processed to locate extreme curvature values, such as peaks and valleys, corresponding to predetermined hand positions and gestures. The number of peaks and valleys are then used to identify and correlate a predetermined hand gesture to the hand image for effectuating a particular computer operation or function.

This invention is an ergonomic method and apparatus for integrating the operation of computer keyboards and cursor control devices. It employs hand location detection to determine when the mouse hand is absent from its keyboard typing position or is present at the mouse. A detector output automatically transforms the functions of a set of keyboard keys lying under the non-mouse hand from their original actions into new actions which can include mouse clicks, keyboard shortcuts and macros. These keys usually include the home keys (a s d f, or j k l ;). The new functions are preprogrammed into this set of keys at an inactive level, and do not affect actions unless the hand position sensor detects that the mouse hand is absent from its keyboard typing position or is present at the mouse. This invention allows the non-mouse hand to actuate clicks at the keyboard by using the home keys as click switches, and also makes it possible for the non-mouse hand to type, with a single keystroke, keyboard shortcuts not normally available to it. When the mouse hand returns to the keyboard the keys automatically revert to their default functions. This method increases working speed, reduces the number of trips back and forth between keyboard and mouse, and relieves stress on the mouse hand. It is of special value to persons with carpal tunnel syndrome or Repetitive Strain Injuries. Detection of hand position or location is accomplished by sensors at the keyboard and / or at the pointing device, or by software detection of any data output from the mouse (movement or click) or from any keypress on the mouse side of the keyboard. This invention can be embodied solely as software, as firmware in an external device or keyboard, or as any combination of software and firmware. It essentially converts the non-mouse side of the keyboard into single-key macros: mouse buttons, tool selection keys, and special function keys. It can also be used to temporarily assign an alternate set of actions to mouse motion, mouse buttons and scrolling devices. Optionally this invention includes a floating on-screen palette which serves as an indicator of transformation and provides a map of the new functions. With simultaneous transformation of both a keyset and its corresponding palette, the palette always displays the new functions in the same geometric pattern as the actual layout of the new functions on the keyboard. This enables eye-to-hand pattern transfer for intuitive tool selection via the keyboard without using the mouse.

A method and system in a portable computer having a display screen for increasing portable computer compactness. Data is displayed initially within the display screen. The display screen is then partitioned into a touch-sensitive input area and a display area, wherein data input at the touch-sensitive input area may be simultaneously displayed in the display area, in response to a particular user input. A test is performed to detect if a user's hands are positioned at the touch-sensitive input area. A touch-sensitive pad is thereafter graphically displayed at the touch-sensitive input area within the display screen, in response to detecting a user's hands positioned at the touch-sensitive area, wherein a user may enter data that may be simultaneously displayed in the display area. An additional test may then be performed to detect if the user's hands are no longer positioned at the touch-sensitive input area. The touch-sensitive pad is subsequently concealed from view, in response to detecting if the user's hands are no longer positioned at the touch-sensitive input area. The touch-sensitive pad graphically displayed at the touch-sensitive input area within the display screen may be composed of a touch-sensitive keyboard, which may in and of itself be an ergonomic keyboard.

All elements of the writing process defining the method can be generated by pen movements such as selection of a key or guiding it in one of eight stroke directions, as well as combinations of these pen movementsThe high speed writing devices described here excel by their small and ergonomically arranged entry sections, whereby all keys for text entry can be reached from one single hand position that never needs re-setting.

In order for a user to control a machine using hand gestures, free of any contact with the machine, an apparatus generates one or more electromagnetic field, employing receivers to measure an electromagnetic signature caused by gestures of a person's hand within the electromagnetic field. The gestures include variations of hand position, proximity, configuration, and movement. For each measured signature, the apparatus cross-references the electromagnetic signature in a predetermined library to identify a corresponding predefined machine-readable input. Ultimately, the apparatus controls a designated machine pursuant to the person's hand gestures by transmitting the identified input to the machine.
