Time-Frequency Characteristics of In-Home Radio Channels Influenced by Activities of the Home Occupant

2019

While aging is a serious global concern, in-home healthcare monitoring solutions are limited to context-aware systems and wearable sensors, which may easily be forgotten or ignored for privacy and comfort reasons. An emerging non-wearable fall detection approach is based on processing radio waves reflected off the body, who has no active interaction with the system. This paper reports on an indoor radio channel measurement campaign at 5.9 GHz, which has been conducted to study the impact of fall incidents and some daily life activities on the temporal and spectral properties of the indoor channel under both line-of-sight (LOS) and obstructed-LOS (OLOS) propagation conditions. The time-frequ…

Når skjermene inntar kirkerommet - om bruk av digital presentasjonsteknikk i gudstjenester

2021

This study aims to elucidate how modern presentation technology is being used by Norwegian Christian congregations. It is based on a survey answered by 715 church leaders, and the practice revealed is discussed particularly on the basis of Eileen D. Crowley's framework for ‘liturgical media art’. The findings show that presentation technology is used to a significant extent, but mainly as practical, visual support for communication. The article argues that there is a potential to use technology for aesthetic purposes as well.
