Acceptance and Preferences of Using Ambient Sensor-Based Lifelogging Technologies in Home Environments

Abstract

Diverse sensor-based technologies can be used to track (older and frail) people’s movements and behaviors in order to detect anomalies and emergencies. Using several ambient sensors and integrating them into an assisting ambient system allows for the early identification of emergency situations and health-related changes. Typical examples are passive infrared sensors (PIR), humidity and temperature sensors (H&T) as well as magnetic sensors (MAG). So far, it is not known whether and to what extent these three specific sensor types are perceived and accepted differently by future users. Therefore, the present study analyzed the perception of benefits and barriers as well as acceptance of these specific sensor-based technologies using an online survey (reaching N=312 German participants). The results show technology-related differences, especially regarding the perception of benefits. Furthermore, the participants estimated the costs of these sensors to be higher than they are, but at the same time showed a relatively high willingness to pay for the implementation of sensor-based technologies in their home environment. The results enable the derivation of guidelines for both the technical development and the communication and information of assisting sensor-based technologies and systems.

Shapes of You? Investigating the Acceptance of Video-Based AAL Technologies Applying Different Visualization Modes

“…The first research question (RQ1) of this study referred to the general perception and acceptance of video-based AAL technology. In line with previous research, the results of this study confirmed that video-based AAL technologies are evaluated on a neutral, slightly rejecting level, indicating that visual approaches are perceived to be more critical than audio or rather binary technologies [ 13 , 14 ], such as room presence sensors, heat sensors, or humidity sensors [ 65 ].…”

“…In addition to the perceived benefits, the results of this study revealed high confirming evaluations of perceived barriers as well, in particular regarding privacy-related aspects, whereas the economic and technical concerns were comparably low. These high confirmations of the (privacy-related) perceived barriers are characteristic of video-based AAL technologies, as previous research clearly identified lower evaluations of these barriers and concerns related to AAL technologies in general [ 14 ] or in specific, such as sensor-based AAL systems [ 65 ]. The high relevance of privacy-related concerns already suggests that communication and information strategies should focus on privacy handling and data security when video-based AAL technologies are implemented.…”

Diffusion of a Lifelog-Based Digital Healthcare Platform for Future Precision Medicine: Data Provision and Verification Study

“…Lifelogs are real-world data of daily lives recorded and stored on personal devices, portable storage systems, or in the cloud. Lifelogging involves a series of procedures that collect and process data through sensors and smart devices [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. A personal health record is considered a dataset consisting of an individual’s lifelog as well as a hospital’s clinical data.…”
