Wearable sensor technology, particularly inertial measurement sensors are used in various motion analysis including applications in sport, medicine, and rehabilitation of patients after stroke. We are interested in deriving biomarkers to evaluate the patient’s recovery trend, motion performance and... Continue

In this collaborative project, including the Reha Clinic in Rheinfelden and the ETH Zürich, we investigated recovery trends in hemiparetic patients afters troke using wearable IMUs. We evaluated algorithms for unsupervised stride detection, walking parameter estimation and trend quantification. In... Continue

An emerging number of  methods are proposed for eating event detection. To assess the detection performance, evaluation metrics such as precision, recall and F1 score are commonly used. However, these popular metrics only give overview of event retrieval performance and do not tell people the absolu... Continue

To provide high-quality dietary assessment of free-living behaviour is the first step for implementing any effective diet coaching and weight management program.  A continuous direct human observation is an expensive and non-scalable solution. Exploiting an unobtrusive wearable camera-based solution... Continue

Personalized 3D-printed eyeglasses equipped with sensing functions can enhance daily life through augmenting applications that enable wearers to monitor their vitals and behaviour. Novel 3D-printing techniques and materials could provide the basis for personalized smart eyeglasses such that the fram... Continue

Almost one third of our lives is spent sleeping and yet many of us struggle finding consistent high-quality sleep. At the same time, smartphones have become our ubiquitous companions, filled with sensors, processing power, and wireless connectivity. Our proposed sleep timing estimation approach uses smartphone sensor information to estimate daily sleep timing. Continue

In data mining, the relationship between variables is extracted from the association of events in a record. For example,  consider a shopping receipt as a record of acquired items and each item as an event. Therefore, data mining looks for the association of products that are usually purchased toget... Continue

ACTLab Activities The particular focus of ACTLab in SimpleSkin is on activity recognition and behaviour inference and patient state interpretation from textile sensor patches in natural free living conditions. For this purpose, new sensor designs are investigated in our lab and proposed for the demo... Continue

WISEglass aims to realise smart eyewear with the perception, performance, and handling of regular eyeglasses. Our approach is based on the observation that most of our senses, vitals, and action involve the head. Smart eyeglasses with regular look thus offer unique and continuous insight into human... Continue
