Gesture based semantic service invocation for human environment interaction

Abstract

The assistance of users in their activities of daily life by a smart environment is the main goal of Ambient Assisted Living (AAL). In this case, interaction is of particular interest since some users are very familiar with modern technology and for some users this technology is very challanging so that poorly designed interaction metaphors will lead to a low acceptance. Additionally, AAL has to cope with the challenges of open systems in which at any time new devices and functionalities can appear. This paper presents a gesture based approach to control devices and their functionalities in a smart environment at a semantic level to issue a command or to set a level. Redundant functionalities are filtered out before presenting the list of functions to the user. This concept is validated by a demonstrator that uses the semantic AAL platform universAAL.
