Currently, connectedness assesment is primarily done through questionnaires. Although questionnaires are good for tapping into the user experience, they also have drawbacks, like memory biases, proneness to social masking, and lack of mental access. Now that sophisticated sensors are becoming cheaper, less obtrusive, and more widely available, this opens doors to more objective continuous measu...

Fall detection based on images is rated obtrusive and costly. This paper presents an unobtrusive fall detection system, which allows a nearly invisible positioning under furniture and cost-efficient integration and scalability in retirement homes via WLAN. The system classifies events using image analysis and notifies the caregiver if an alarming event occurred. It was successfully tested in a ...

Here we present a new method for automatic and objective monitoring of ingestive behaviors in comparison with other facial activities through load cells embedded in a pair of glasses, named GlasSense. Typically, activated by subtle contraction and relaxation of a temporalis muscle, there is a cyclic movement of the temporomandibular joint during mastication. However, such muscular signals are, ...

We present a novel class of virtual reality input devices that combine pop through buttons with 6 DOF trackers. Compared to similar devices that use conventional buttons, pop through devices double the number of potential discrete interaction modes, since each button has two activation states corresponding to light and firm pressure. This additional state per button provides a foundation to add...

l2 research has shown that instruction in l2 pragmatics is necessary. the current study evaluated the impact of explicit instruction on efl learner's awareness and production of three speech acts of request, apology, and complaint. it also probed whether learners’ language proficiency plays any role in incorporating pragmatic instruction into the l2 classroom. iranian undergraduate students maj...

This paper focuses on developing and assessing a non-obtrusive transformative method, based virtual reality, to evaluate science communication projects in centres. The method was tested using deep-sea cutting-edge scientific content. We applied mixed design, with 72 adult participants randomly assigned experimental conditions (with/without exhibition exposure). Results showed that the promoted ...

OBJECTIVE Stress at work is a significant occupational health concern. Recent studies have used various sensing modalities to model stress behaviour based on non-obtrusive data obtained from smartphones. However, when the data for a subject is scarce it becomes a challenge to obtain a good model. METHODS We propose an approach based on a combination of techniques: semi-supervised learning, en...
