Services and Applications for Smart Office Environments - A Survey of State-of-the-Art Usage Scenarios

Authors/Creators

Description

This paper reports on a survey of state-of-the-art application scenarios for smart office environments. Based on an analysis of ongoing research activities and industry projects, functionalities and services of future office systems are extracted. In a second step, these results are used to identify the key characteristics of emerging products.
