tomorrow: appliances serve the user according her/his current needs


What Is EWhat Is EUNICAUNICA??

Platform for Remote Controlling and

Monitoring Household Appliances


EEUNICAUNICA Enables ... Enables ...

to connect arbitrary kind of appliance

to connect appliance by arbitrary connection method

to load and execute control program for the appliance

to communicate control programs inside the control unit


Our Innovative IdeasOur Innovative Ideas

Modularity simple addition of an arbitrary appliance

Mobility remote control and monitoring of appliances

within a household or outside of the household

Adaptability user controlled adaptability event-controlled adaptability system-controlled adaptability

Sophisticated Control of Access Rights multilevel permission checking enhanced by

biometric identification

Access Rights ControlAccess Rights Control Levels of access rights

the whole system the group of appliances specific appliance some of appliance’s features (requires

appliance driver support)

Authority structure in the Control unit multilevel permission checking

Users can restrict access for other users Permission checking before realizing a

user request (by responsible appliance driver)


SecuritySecurity

Communication between Control unit and appliances

using inherent protection of communication technology

using encryption modules inside Control unit

Communication among modules inside Control unit

using independent component architecture each module has own ID and wouldn’t

change it

Avoiding misuse of appliances and data in the Control unit

Digital sign of modules


Security (cont.)Security (cont.)

Three security levels in the use of appliance functions

Publicly available functions Restrictions (initial identification of the

user is sufficient) Protected functions (additional

identification is demanded)

Benefits ...Benefits ... to Society

easy and secure monitoring and controlling of appliances for all, including specific groups of users (children, elder or disabled people)

to Informatics Research and Practice adaptive and adaptable user interfaces modular architecture, unification of various

ways of appliance control and monitoring

to Ourselves improved skills necessary to work in team improved design skills getting in touch with emerging technologies

and development environments


FutureFuture

Extending Control unit with specific modules

New types of user identification Localization of the user Defining and executing macros New appliances and groups of appliances

Extending EUNICA to distributed system involving several Control units
