A touchless input device has image sensors on the side of a surface to capture the positions and movement of fingers or any visible objects working near or on the surface. Embodiments include touchless data entry keyboards, touchless pointing devices, and touchless screens. It provides better performance, finer resolution, and more clearly defined action space than infrared beam based touchless input devices. In particular, one embodiment merges the space for data entry and the space for cursor movement into one and reduces the number of devices and working space needed by users.

Touchless input devices using image sensors

A method of utilizing raised parts on a keypad surface, called separation walls, is disclosed. Separation walls can help prevent unintended key hits so that keys can be smaller and be placed with higher densities on small devices. Separation walls with slits can also make light beam keypads operable with multiple fingers at a higher input speed.

Means for setting separation walls with predetermined heights and shapes on keypads to prevent unintended key hits

A system architecture for managing a group of heterogeneous workstations that may be widely dispersed geographically. A system according to the present teachings enables users to access remote workstations and run applications on the remote workstations transparently and enables seamless integration of remote desktop sharing and distributing desktops among heterogeneous workstations. The system also provides enforcement of protections among user and workstations, user account management and workstation allocation management. The present architecture is platform independent and enables workstations to be accessed from anywhere using a graphical user interface through the Internet.

System architecture for wide-area workstation management

A system for automatic management of an e-service which partitions an e-service life-cycle among operational functionalities and non-operational functionalities and tends to the operational functionalities, thereby reducing the development burden of an e-service and enabling e-service owners to stay more focused on business related issues. In addition, a system according to the present teachings facilitates the smooth transition among the phases of an e-service life-cycle and facilitates the partition of system functionality into physically distributed components.

Automatic management of e-services

An optical input apparatus includes a light source of a directional light beam and a receiving module. The receiving module contains a collection of photodetectors through which information can be input into a system by pointing the light beam at various photodetectors. The photodetectors can be so arranged that all the functionalities of the standard computer keyboard and mouse can be performed by this apparatus. Such an input interface reduces greatly the factors that may cause repetitive strain injuries and can be used by people having difficulties operating a keyboard and mouse. The most preferred embodiments are for computer mouse and keyboard. Other hand operating devices, such as Personal Digital Assistants and remote controls can all make use of the advantages offered by this apparatus.
