“…Yoshida et al [40] suggested that it is possible to artificially manipulate emotional states using visual feedback of deformed facial expressions in real-time. Macdonald et al [41] observed affective responses to emotionally resonant vibrotactile stimuli that evoke real-world sensations. Vibrotactile properties such as vibration duration and pattern were also used in information and emotion communication between couples [42].…”

Research from psychology has suggested that body movement may directly activate emotional experiences. Movement-based emotion regulation is the most readily available but often underutilized strategy for emotion regulation. This research aims to investigate the emotional effects of movement-based interaction and its sensory feedback mechanisms. To this end, we developed a smart clothing prototype, E-motionWear, which reacts to four movements (elbow flexion/extension, shoulder flexion/extension, open and closed arms, neck flexion/extension), fabric-based detection sensors, and three-movement feedback mechanisms (audio, visual and vibrotactile). An experiment was conducted using a combined qualitative and quantitative approach to collect participants’ objective and subjective emotional feelings. Results indicate that there was no interaction effect between movement and feedback mechanism on the final emotional results. Participants preferred vibrotactile and audio feedback rather than visual feedback when performing these four kinds of upper body movements. Shoulder flexion/extension and open-closed arm movements were more effective for improving positive emotion than elbow flexion/extension movements. Participants thought that the E-motionWear prototype were comfortable to wear and brought them new emotional experiences. From these results, a set of guidelines were derived that can help frame the design and use of smart clothing to support users’ emotional regulation.

“…The Haptic Remembrance Book utilised pictures, sound and haptics to help elderly users reminisce about past experiences [15]. Macdonald et al [34] converted real-world sounds to vibrations to produce new emotionally resonant haptic stimuli and Shim et al utilised a 3x3 array of vibrotactile motors to craft cues emotionally resonant cues [51], eliciting a wider than typical range of affective responses.…”

“…In addition, they also indicated preferences from a pre-selected assortment of stimuli intended to encourage them to consider other ideas. Whilst our focus was on affective haptics, we included audio as these suggestions can effectively derive haptic designs [34], lead to cues with cross-modal correspondence for increased valence [19,35] and allowed participants to suggest more sensations they have lived experience with while revealing the wider calming experiences they wish to experience.…”

“…After suggesting stimuli through open text responses, we then asked them to choose multiple options from a predefined selection of 18 stimuli that may also be relaxing (listed in Table 3). These were based on suggestions from the research team and those used in prior work on affective stimuli [34]. This question produced further data on which experiences participants want and gave them the option to register interest in stimuli they did not consider.…”

“…This survey prompted users to make either tactile or audible suggestions for three reasons. Auditory and haptic often have strong cross-modal correspondence and some sounds have been successfully evoked using haptic technology with pleasant results [15,34]. Auditory suggestions also inform the a wider variety of experiences that users want , allowing for exploration of related haptic sensations.…”

This paper presents a survey informing a user-first approach to designing calming affective haptic stimuli by eliciting user preferences in different social scenarios. Prior affective haptics research presented users with stimuli and recorded emotional responses. By contrast this work focuses on the sensations users wish to experience and how these can be simulated using haptics. The survey (n=81) investigated which users preferences in four social situations to reduce social anxiety. Using thematic analysis of responses we created a coding scheme of stimuli derived from real-world experiences to emulate with affective haptics. By cross-referencing these categories with affective haptics research, we provide recommendations to designers about which calming stimuli users wish to experience socially and how they can be implemented.
