    SwellFit: Developing A Wearable Sensor for Monitoring Peripheral Edema
    ( 2019-01-08) Kim, Sunyoung ; Iravantchi, Yasha ; Gajos, Krzysztof
    Peripheral edema is a swelling of the legs, feet, or hands due to the accumulation of excessive fluid in the tissues. For patients with some chronic diseases, peripheral edema is a crucial indicator of onset or exacerbation of the condition. Thus, early detection of peripheral edema is important for timely diagnosis of associated diseases. However, existing techniques for edema assessment are a subjective measurement for which a human operator estimates the amount of swelling using a tape measure or by pressing the swollen area with the tip of an index finger. As a systematic approach to assessing peripheral edema, we develop SwellFit, an experimental prototype of a novel wearable technology that monitors peripheral edema by tracking changes in ankle curvature. Through a series of proof-of-concept experiments, we demonstrate that SwellFit detects ankle swelling even in the presence of substantial noise in the raw sensor readings.

    Wearable Devices for Health and Wellbeing: Design Insights from Twitter
    ( 2019-01-08) El-Gayar, Omar ; Nasralah, Tareq ; Elnoshokaty, Ahmed
    Wearable devices are increasingly recognized for their potential to improve health and wellbeing. However, challenges remain for wide-scale adoption and use. This paper explores perception and reactions towards wearable devices with a particular emphasis on factors that influence the adoption and use to improve health and well-being and which can also inform their design as components of a behavioral change system. We use social media analytics to analyze and categorize tweets related to major manufacturers of consumer wearable devices from June 1, 2017 – May 31, 2018. We used extant literature on the design of persuasive systems to inform the definition of pertinent categories. The findings confirmed the relevance of persuasive design features such as Dialog, credibility, and social support, though to various degrees. The analysis sheds light on other user priorities pertaining to device characteristics, integration with other systems, issues surrounding actually wearing these devices on a regular basis.

    Transforming Personal Healthcare through Technology - A Systematic Literature Review of Wearable Sensors for Medical Application
    ( 2019-01-08) Witte, Anne-Katrin ; Zarnekow, Rüdiger
    Wearable Sensor Health Technology (WSHT) captures, analyzes and aggregates physiological data to improve personal well-being. Recently the technology market is flooded with wearable sensors that measure health-related data and have a high user adoption. Nevertheless, these devices are almost exclusively used for fitness purposes and the healthcare sector still faces the challenge of constantly increasing costs. To respond to the necessary but rare use of WSHT in professional healthcare, we aim to identify the most promising areas for future medical implementation. Therefore, we performed a systematic literature search and reviewed 97 papers with regard to disease treatment, application area, vital parameter measurement and target patient. As a result, we could identify five potential areas for further research: (RA1) concentration on widespread diseases, (RA2) expansion of WSHT’s functionality, (RA3) diversity of vital parameter measurements, (RA4) proactive analysis of sensor data for preventive purposes and (RA5) promoting patient adoption through enhanced usability.
