“…As the proliferation of audio–visual communication pushes human information processing capacity to its limits, researchers are turning to touch as a means of conveying information to relieve overloaded visual and auditory perceptual channels 1 – 3 . Recent years have seen a surge in haptic feedback research to augment or substitute visual or auditory notification methods in a wide spectrum of applications such as driver–vehicle interaction 4 , mobile phone communication 5 , interaction with visually or auditory impaired individuals 6 , and soldier–battlefield interaction 7 . Haptic feedback does not increase visual and/or auditory demands 8 , is robust to audible noise 9 , engages people at different emotional levels 10 , and is confidential 11 .…”

Conveying information effectively while minimizing user distraction is critical to human–computer interaction. As the proliferation of audio–visual communication pushes human information processing capabilities to the limit, researchers are turning their attention to haptic interfaces. Haptic feedback has the potential to create a desirable sense of urgency that allows users to selectively focus on events/tasks or process presented information with minimal distraction or annoyance. There is a growing interest in understanding the neural mechanisms associated with haptic stimulation. In this study, we aim to investigate the EEG correlates associated with the perceived urgency elicited by vibration stimuli on the upper body using a haptic vest. A total of 31 participants enrolled in this experiment and were exposed to three conditions: no vibration pattern (NVP), urgent vibration pattern (UVP), and very urgent vibration pattern (VUVP). Through self-reporting, participants confirmed that the vibration patterns elicited significantly different levels of perceived urgency (Friedman test, Holm–Bonferroni correction, p < 0.01). Furthermore, neural analysis revealed that the power spectral density of the delta, theta, and alpha frequency bands in the middle central area (C1, Cz, and C2) significantly increased for the UVP and VUVP conditions as compared to the NVP condition (One-way ANOVA test, Holm–Bonferroni correction, p < 0.01). While the perceptual experience of haptic-induced urgency is well studied with self-reporting and behavioral evidence, this is the first effort to evaluate the neural correlates to haptic-induced urgency using EEG. Further research is warranted to identify unique correlates to the cognitive processes associated with urgency from sensory feedback correlates.

“…A situation with psychological constraint refers to a situation where there is a restriction on the use of the smartwatch due to psychological pressure, such as being in a meeting or having communication with others. Visually identifying the information received on the smartwatch in the context of physical or psychological constraints can result in a high cognitive load on the user and can result in misrecognition of the information received [8]. erefore, we are going to explore a method to transmit information to smartwatch users which does not require visual attention.…”

As smartwatches gain popularity in the marketplace, various smartwatch context studies have been conducted. The use of smartwatches can be divided into situations with and without constraint both physically and psychologically. Notably, in constrained situations, if the user wants to check the information received in the smartwatch visually, a high cognitive load is involved. To solve this problem, we propose a method to encode and transmit information from the smartwatch with haptic pulses. First, we determine the informational category of the smartwatch and generate various haptic pulses. Next, we propose and verify a haptic pulse set that can represent the informational category of the smartwatch. Using the proposed haptic pulse set, users can receive smartwatch information in constraint situations. The use of encoded haptic pulses needs to be considered to provide information effectively from the smartwatch to the wearer.
