虽然许多新技术已经被用于压力检测，但向用户传达压力仍然主要通过视觉或听觉渠道。然而，这些常用的反馈渠道已经与智能手机通知联系在一起。相反，我们专注于热反馈，由于其不引人注目而产生保护隐私的优势。通过这项工作，我们对热反馈进行了调查，以通知用户有关应力，包括探索首选温度水平，变化率和身体位置。因此，我们比较了21名参与者在用户研究中的不同刺激。从他们的定量和定性反馈中，我们发现冷刺激在一般情况下更受欢迎，表明±- 0.5◦C是最佳的变化率，最好出现在下背部。最后，我们从定量和定性数据中讨论了我们的发现，并最后提出了我们的研究议程，为热反馈作为应力通知铺平了道路。
Though many new technologies have been adopted for stress detection, communicating stress to the users is still experienced primarily through visual or auditory channels. However, these commonly used feedback channels are already associated with smartphone notifications. Instead, we focus on thermal feedback yielding the advantage to preserve privacy due to its unobtrusiveness. By this work, we contribute an investigation of thermal feedback for notifying users about stress comprising the exploration of the preferred temperature level, rate of change, and body location. Accordingly, we compared different stimuli for each for those in a user study involving 21 participants. From their quantitative and qualitative feedback, we found that cold stimuli are preferred in general, showing that ± − 0.5◦C is the optimal rate of change and preferably when presented at the lower back. We conclude with discussing our findings from both the quantitative and qualitative data and finally present our research agenda paving the way for thermal feedback as a stress notifier.
