Abstract:

A method and apparatus for social interaction allowing users to communicate at their leisure by providing simple, flexible access to a persistent, shared space. An electronic communication system provides a shared persisten data space to a plurality of clients. This system comprises a server and at least two input/display units (IDUs) which clients use to access shared persistent data in the form of group boards. The group boards store discrete notes in a group database made accessible to all members of the group. Each IDU includes an input detection space operable to receive user input indicative of a request to access a specific group. The input detection space can take on many forms such as electromechanical buttons, touch or pressure sensitive devices, a digital inking device, a token input device, or a voice command device. Each IDU als includes a note data input device. Examples of suitable note data input devices may be a touch, stylus or pressure sensitive devices. A scanning device also works well, creating a unique persistent space wherein users can exchange discrete note messages of a variety of forms such as handwritten notes and photographs.
