One of Bob Sottilare’s undergraduate students, while interning for Sottilare, wanted to investigate the efficacy of measuring heart rate unobtrusively. A few years before that, Bob had been at an affective computing conference at the University of Memphis and he ran into Rosalind Picard, who ran the MIT affective computing laboratory. (Affective here means relating to moods, feelings, and attitudes.) One of her grad students had developed a method to use webcams to measure heart rate. The webcams collected data through red-green-blue channels. It turns out that if the green and blue channels were eliminated and the camera was pointed just above a person’s eyes, the intensity of the red channel could be sensed, and a person’s heartbeat could be visualized. At first, this seemed like a much less obtrusive alternative for measuring heart rate. However, sensors have limits. In this case, distance was a major limitation. As the user moved away from the camera, the number of pixels focused on the sweet spot of heavy blood flow between and above the eyes lessened and so did the accuracy of the heart rate monitor.
Physical Recovery
Published in Stijn Geerinck, Reconstructing Identity After Brain Injury, 2022
A realistic approach of my new objectives was paramount if I wanted to succeed. I went about it well-prepared. To exert control over all possible aspects, I used my heart rate monitor and GPS more intensively than ever before. I made sure to stay well within the limits of my physical abilities by rationally analysing my level and carefully monitoring my speed. I kept it low enough so I could keep up the pace, only increasing it to improve my condition for the sake of recovery, no longer to break personal records. I started out exceptionally slow and only marginally increased the speed. Long-distance running turned out to be the most workable discipline for my condition. I made a path by treading it, race-walking it out of nothing.
Turn It Off – Relaxation Training

If you’re the kind of person who likes “data” there’s a fun way to incorporate simple biofeedback into this by watching your heart rate rise and fall while you breathe. Either use a device that gives you a pulse reading (a fit bit, smartwatch, exercise heart rate monitor, or pulse oximeter) or simply put your fingers on a pulse point at your wrist or neck. During the inhale, your heart will speed up a little, and then during the exhale it will slow down. That’s the effect of the parasympathetic nervous system. As you slow and deepen your breathing, your overall heart rate will go down, but you’ll still notice that it beats faster while you inhale and slower while you exhale. If you can notice that, you’re doing it right! Weirdly, the ability to maximize heart rate “variability” (the difference between the slow and fast beats) is a sign of both cardiovascular health AND good emotion regulation skills. It means you can both rise to a challenge (with sympathetic activation) AND calm yourself down quickly afterward (with parasympathetic activation).
Women’s embodied experiences of using wearable digital self-tracking health technology: A review of the qualitative research literature

In contrast, other women described the digital device as allowing them to discover information about their bodies and actions that was not easily visible to them. One woman who participated in an internet facilitated pedometer intervention, for instance, suggested that she had been unaware of how sedentary her lifestyle had become: “it really gave me and eye opener … I think it’s excellent in showing people, giving people a reality check” (McCormack et al., 2019, p. 4). Women thus described that gaining insight and becoming more bodily aware inspired them to change their way of being in their bodies, and in particular carrying out physical activities. For one elderly woman, using a heart rate monitor meant that she was able to see and keep track of an otherwise inaccessible and worrisome part of her body: “my heart rate monitor shows the heart, my heart” (Urban, 2017, p. 6). She described that by monitoring her heart while out walking she could avoid harming her heart, which in turn meant that she could continue to live unassisted in her own home. Another woman, who took part in a study on self-tracking practices during running, suggested that the data produced by her digital watch provided an opportunity to reflect upon and understand her physical actions better: “the data is a gateway to like, what did I do that made this number (heart rate) the way that it is?” (Esmonde, 2019a, p. 812). She also explained that using the watch: “helps you establish a routine at a pace that works for your body” (Esmonde, 2019a, p. 813).
Simultaneous assessment of motor and cognitive tasks reveals reductions in working memory performance following exercise in the heat

Height and weight were measured with a stadiometer and scale (Satorius Corp., Bohemia, NY, USA). Urine-specific gravity was measured using a handheld refractometer (Atago, Bellevue, WA). Nude body weight was measured pre- and post-exercise after towel drying. Heart rate was measured using a standard heart rate monitor (Polar Electro, Bethpage, NY, USA). Approximately 90 minutes prior to experimental testing, each subject swallowed a telemetry pill (HQ Inc., Palmetto, FL, USA) for the measurement of core temperature. This approach provides a valid measure of core temperature, particularly when drinking is prohibited [29]. Mean skin temperature was measured as the weighted average of four thermochron iButtons (Maxim Integrated, San Jose, CA, USA) using the following equation: 0.3 · (chest + triceps) + 0.2 · (quadriceps + calf) [30].

The smovey® vibroswing is a swinging-ring system which can be used for exercise and regular physical activity. It consists of a spiraled tube, four steel balls, and a grip. When a forward motion is performed (and this is then followed by a direct countermovement), the four steel balls roll inside the tube and produce a pulsating vibration in the patient’s hands. The weight of one ring is around one pound at rest. Through the centrifugal forces which are created by the swinging motion, the perceivable mass can rise up to almost 12 pounds. The exercise-program consisted of simple and time efficient movements with moderate intensity [15]. The patients were instructed how to use the swinging-ring system. The goal was to perform regular exercise each day. In the first 3 months, a supervised exercise group (together with a Turkish speaking female physician) was offered to the patients once a week. Additionally, the participants could choose how to use the smovey® vibroswing, e.g., only indoor or only outdoor (single or in a group) or both. Exercise intensity was set at a moderate level according to the Borg rating of perceived exertion scale (BORG) [15,16]. The heart rate was controlled at rest, during exercise and after exercise by using a Polar® heart rate monitor watch. The watches were synchronized to the Turkish language according to the individual data of participants (age, body weight, height).
