“…It is an excitatory, emotional signal for conveying high-level impressions. Thermal feedback has been shown to be effective and convincing in mimicking object/surface thermal properties in virtual reality [5,16]. However, this was not a common usage for thermal feedback by participants here.…”

“…Thermal feedback in HCI may be capable of improving user experience by bridging the gap between data and their underlying social or emotional content. It has been used in HCI to convey information [1,21], improve materiality [5,16] or for communication [14,18]. However, most research has either been technological, developing new ways of providing thermal feedback [1], or perceptual, testing how well participants can detect or identify thermal stimuli [21,22].…”

Research has shown that thermal feedback can be an engaging and convincing means of conveying experimenterpredefined meanings, e.g., material properties or message types. However, thermal perception is subjective and its meaning in interaction can be ambiguous. Interface designers may not be sure how users could naïvely interpret thermal feedback during interaction. Little is also known about how users would choose thermal cues to convey their own meanings. The research in this paper tested subjective interpretations of thermal stimuli in three different scenarios: social media activity, a colleague's presence and the extent of use of digital content. Participants were also asked to assign their own thermal stimuli to personal experiences, to help us understand what kinds of stimuli people associate with different meanings. The results showed strong agreement among participants concerning what warmth (presence, activity, quality) and cool mean (absence, poor quality). Guidelines for the design of thermal feedback are presented to help others create effective thermal interfaces.

“…The capability of thermal stimuli to evoke emotions has been demonstrated in isolation [20,58,73], or to augment media [67,47,58]. The latter is part of a growing trend in HCI across a range of interaction scenarios, including conveying (emotional) information through temperature displays [67], improving material properties of virtual content [54], or communicative functions [25,16,39].…”

Voice is a rich modality for conveying emotions, however emotional prosody production can be situationally or medically impaired. Since thermal displays have been shown to evoke emotions, we explore how thermal stimulation can augment perception of neutrally-spoken voice messages with affect. We designed ThermalWear, a wearable on-chest thermal display, then tested in a controlled study (N=12) the effects of fabric, thermal intensity, and direction of change. Thereafter, we synthesized 12 neutrally-spoken voice messages, validated (N=7) them, then tested (N=12) if thermal stimuli can augment their perception with affect. We found warm and cool stimuli (a) can be perceived on the chest, and quickly without fabric (4.7-5s) (b) do not incur discomfort (c) generally increase arousal of voice messages and (d) increase / decrease message valence, respectively. We discuss how thermal displays can augment voice perception, which can enhance voice assistants and support individuals with emotional prosody impairments.

“…In the proposed method, two temperature parameters, i.e., thermal change rate and thermal intensity, are both manipulated to represent colours. To make the produced thermal stimuli comfortable, we chose a temperature range between 21°C and 39°C to represent colours, with the initial skin temperature adapted to 30°C, a neutral temperature also used in [21]. Three different stimuli intensities were used: 3°C, 6°C and 9°C.…”

This paper proposes a novel method of manipulating both thermal change rate and thermal intensity to convey colour information by using a thermal tactile display. The colourspace transformation from {red, green, blue} to {hue, saturation, intensity} is introduced, and the mapping between colour and temperature is established based on warm and cold colours. Considering the lower resolution of the tactile channel, six limited stimulation levels are generated to represent colours. Based on the semi-infinite body model, the thermal response within the skin for each stimulation form is investigated. The Peltier element of the display is designed to convey different thermal stimuli to the human finger. Two experiments are performed to evaluate the performance of the display: colour identification and discrimination. Experimental results indicate that there is a response bias among the perceived colours for the traditional method of only employing thermal intensity, but there is no response bias for the proposed method; subjects' mean recognition accuracy with the proposed method is significantly higher than that gained using the traditional method. Furthermore, colour information of the captured images can be reliably discriminated by using this devised thermal tactile display.
