Current digital systems are largely blind to users' cognitive states. Systems that adapt to users' states show great potential for augmenting cognition and for creating novel user experiences. However, most approaches for sensing cognitive states, and cognitive load specifically, involve obtrusive technologies, such as physiological sensors attached to users' bodies. This paper present an unobtrusive indicator of the users' cognitive load based on thermal imaging that is applicable in real-world. We use a commercial thermal camera to monitor a person's forehead and nose temperature changes to estimate their cognitive load. To assess the effect of different levels of cognitive load on facial temperature we conducted a user study with 12 participants. The study showed that different levels of the Stroop test and the complexity of reading texts affect facial temperature patterns, thereby giving a measure of cognitive load. To validate the feasibility for real-time assessments of cognitive load, we conducted a second study with 24 participants, we analyzed the temporal latency of temperature changes. Our system detected temperature changes with an average latency of 0.7 seconds after users were exposed to a stimulus, outperforming latency in related work that used other thermal imaging techniques. We provide empirical evidence showing how to unobtrusively detect changes in cognitive load in real-time. Our exploration of exposing users to different content types gives rise to thermal-based activity tracking, which facilitates new applications in the field of cognition-aware computing. CCS Concepts: • Human-centered computing → Human computer interaction (HCI); • Computing methodologies → Cognitive science; • Hardware → Displays and imagers;

“…Though slow/deep breathing often leads to relaxation, future experiments will need to assess the effectiveness of Sonic Respiration by measuring changes in HRV and EDA, as we have done in prior studies [11]. Future work will also test the effectiveness of different music genres in eliciting slow breathing patterns.…”

We present an auditory biofeedback technique that may be used as a tool for stress management. The technique encourages slow breathing by adjusting the quality of a music recording in proportion to the user's respiration rate. We propose two forms of acoustic degradation, one that adds white noise to the recording if the user's breathing deviates from the target rate, and another that reduces the number of channels in a multi-track recording. Validation on a small user study indicates that both techniques are equally effective at reducing respiration rates while performing a secondary task, though user feedback indicates that additive noise is a more intuitive form of sonification.

“…However, within the HCI community the use of biofeedback to distract or calm down users in a hospital setting has received less attention. As we highlight later in this paper, designing for and conducting evaluations in a hospital context requires interventions to be sterile and in most cases there is not time for a patients to put on the special equipment required to detect breath or respiration in many of the existing stress relieving biofeedback applications [19,29,36,38].…”

Blood sampling is a common and necessary procedure in the treatment and diagnosis of a variety of diseases. However, it often results in painful and stressful experiences for children. Designed together with domain experts, Pufferfish is a breath-controlled biofeedback game technology with bespoke airflow sensor that aims to calm children during blood sampling procedures. An initial randomized controlled trial was conducted in which 20 children aged 6-11 were assigned to one of two conditions involving either passive distraction (watching a video) or active distraction using the Pufferfish prototype. Medical staff rated Pufferfish significantly more useful in facilitating the blood sampling procedure compared to passive distraction. Qualitative feedback from patients, parents, and medical staff identified aspects that impact the acceptance of breath-based active distraction. Our study highlights the potential of non-pharmacological assistive technology tools to reduce fear and pain for children undergoing painful or stressful medical treatment.
