“…In a previous study in which subjects were observed during a mentally stressful condition [2], reciprocal synergies, as specified by Elliott and Connolly [3], appeared to be the most frequently observed object manipulations movements when using a pen in a stressful situation as compared to a non-stressful situation. According to Elliott and Connoly's classification reciprocal synergies include, twiddle, rock, radial roll, index roll, and full roll (see for examples figure 1).…”

Affective computing focuses on the interpretation of users emotions via physiological and behavioral inputs. Irrelevant gestures with a pen were found to increase when users were given a mentally demanding task. Accordingly, an embedded tangible interface was developed which afforded and measured a rolling behavior, and guided the user towards reaching a balanced state of movement. During informal evaluations users acknowledged how the device could contribute to stress reduction. Conclusion, tangible interfaces appear to offer a non-obtrusive means towards interpreting and reducing stress in the office work context.

“…A pen was selected to illustrate the concept because a study on nervous habits by Hansen et al [15] found that 63% of college students ''play with pens and pencils.'' Furthermore, rocking and rolling movements with a pen were previously defined as indicators of stress [8]. In addition, the pen appeared to be an inconspicuous object that is of general use and fits the context as it can unobtrusively sense implicit behaviors.…”

“…The affective loop provides a clear vision on how the product could respond to emotional interaction, such as nervous behaviors with a pen that could be considered as implicit expressions of stress [8]. However, all projects exploring the affective loop rely on the cognitive skills of the user and do not present feedback that addresses the perceptual motor skills.…”

Sometimes, the way in which we interact with products implicitly communicates how we feel. Based on previous studies on how emotions can be detected and communicated via product interaction, we discuss how an interactive product could influence affect by responding and changing behaviors expressing affect. We discuss the proposal of the affective feedback loop in product interaction by its implementation in the prototype of a pen that senses two implicit behaviors related to restlessness, rock and roll. Furthermore, the pen provides inherent feedback, focusing on the perceptual motor skills, as a means to reflect on these behaviors. The pen was evaluated in an experiment, by which we explored whether this type of feedback would influence the emotional experience. Two participant groups were compared, and participants that used the pen with feedback showed a lower heart rate throughout the whole experiment. Because these participants were not aware that the pen provided any feedback, we propose the concept of unaware interaction and discuss what its implications are for design.

“…Bruns et al [2] found that two fidgeting behaviors with a pen, roll and rock, are indicators of stress. A pen can be equipped with sensors that recognize these behaviors and different actuators could provide multimodal feedback.…”
