Human Interaction Interface And Applications

The emergence of Computer Supported Cooperative Work (CSCW) has introduced the development of systems which actively support cooperative work and human-human interactions. The interfaces for supporting cooperative work, called interfaces for human-human interfaces(HHI), are needed to be developed.Most software products, even some already support simultaneous interactions by more than one user; examples include timed operating systems, multiuser MIS systems, prohibit cooperation. Users are not aware others' activities. But CSCW must allow users to be aware the activities of others through HHI. The thesis first discusses the concept , architecture, design, implementation of HHI, then presents the design and implementation of an multimedia interface for human-human interactions (MHHI), which has been applied to teleconsultation and cooperative design. The main works of the thesis are:Discussion of the novel concept of HHI. HHI has research contents for supporting cooperative work, however, it is important for human-human interactions, through HHI, users do not have feeling that they are interacting with computers , called "computer -aware" but with people, called "people-aware".A new architecture for HHI. The architecture, called cooperative architecture, adopts the advantages of two existing architecture and overcome their shortcomings. The central architecture has a central server program which handles all user input and display output events. The central architecture simplifies access management and data consistency, but its delayed feedback. The replicated architecture maintain the copies of applications on each computer which handles feedback locally, so it has fast feedback. But the major difficulties are synchronization and data consistency. Based on multiple servers , the cooperative architecture have a central server to handle the organization of a cooperative session, other servers associated with applications are responsible with communication management of these...
