are not sufficient in intelligent environments Access to information inside the environment has

to be limited Multiple inhabitants should have access to different parts

of the available information Home interfaces and displays have to follow

privacy rules Interfaces can not display private information

Access inside the environment might have to be restricted

Private spaces in office environments Access restrictions to ensure safety of inhabitants

Remote Interface Example: Georgia Tech Aware Home Actual Environment:

Pressure sensitive floors

Microphone arrays Video cameras

Remote Interface Example: Georgia Tech Aware Home Family Portraits:

Summarize daily activityand long-term trends iconically

Limits access to information Provides peace of mind for adult children

Privacy in Intelligent Interfaces Interface should only display the required

information Hide sensory data

E.g. no video data, no exact data on current actions Only display result of processing

E.g. only display if everything is ok

Interface structure should reflect the necessary information Interfaces have to be practical and easy to use without

revealing information E.g. only display static, pre-recorded image of person
