We evaluated the convergent validity of the new language-independent EmojiGrid rating tool for the affective appraisal of perceived touch events. The EmojiGrid is a rectangular response grid, labeled with facial icons (emoji) that express different degrees of valence and arousal. We previously showed that participants can intuitively and...

In this work, we demonstrate a capacitive coupled data transfer with flexible thin-film electronics using touchscreen as ubiquitous reader interface. The capacitive communication to the touchscreen is proven using a 64-bit metal-oxide thin-film capacitive-coupled identification tag. The tag is powered by a thin film battery or thin-film...

Social touch interactions can, depending on the type and strength of the dyadic social relationship, elicit a plethora of physiological, emotional, and behavioral responses; both beneficial and disadvantageous. With the intention to expand the communicative capabilities of humanoid social robots, we investigated whether robot-initiated touches...

Social touch forms an important aspect of the human non-verbal communication repertoire, but is often overlooked in human–robot interaction. In this study, we investigated whether robot-initiated touches can induce physiological, emotional, and behavioral responses similar to those reported for human touches. Thirty-nine participants were...

In order to advance the understanding of affective touch perceptions, and in particular to inform the design of physical human-robot interactions, an online video study was conducted in which observed stroking touches were assessed on perceived pleasantness. Touches were applied at different velocities and either with a human hand, a robot hand,...

Gentle stroking touches are rated most pleasant when applied at a velocity of between 1–10 cm/s. Such touches are considered highly relevant in social interactions. Here, we investigate whether stroking sensations generated by a vibrotactile array can produce similar pleasantness responses, with the ultimate goal of using this type of haptic...

Previous research has shown that odorants consistently evoke associations with textures and their tactile properties like smoothness and roughness. Also, it has been observed that olfaction can modulate tactile perception. We therefore hypothesized that tactile roughness perception may be biased towards the somatosensory connotation of an...

One of the research areas within affective Computer Mediated Communication currently under investigation is that of mediated social touch. A social touch is a complex composition of different physical parameters that can be simulated by haptic technologies. In this article we argue why we think it makes sense to incorporate warmth - and in...

Recent research suggests that physical warmth activates perceptions of metaphorical interpersonal warmth and closeness, and increases pro-social behavior. These effects are grounded in our earliest intimate experiences: being held by our loving caregivers. These findings provide reasons to incorporate warmth in devices for distant affective...

Touch is our primary non-verbal communication channel for conveying intimate emotions and as such essential for our physical and emotional wellbeing. In our digital age, human social interaction is often mediated. However, even though there is increasing evidence that mediated touch affords affective communication, current communication systems ...

This study investigated whether communication via mediated hand pressure during a remotely shared experience (watching an amusing video) can (1) enhance recovery from sadness, (2) enhance the affective quality of the experience, and (3) increase trust towards the communication partner. Thereto participants first watched a sad movie clip to...

We present "Nakama": A communication device that supports affective communication between a child and its - geographically separated - parent. Nakama consists of a control unit at the parent's end and an actuated teddy bear for the child. The bear contains several communication channels, including social touch, temperature, and vibrotactile...

Social touches are essential in interpersonal communication, for instance to show affect. Despite this importance, mediated interpersonal communication oftentimes lacks the possibility to touch. A human touch is a complex composition of several physical qualities and parameters, but different haptic technologies allow us to isolate such...

To enable the design of more intuitive product user interfaces, the prospects of matching piezoelectric touch sensors with flexible organic light emitting diode (OLED) technology are investigated. Low stiffness piezoelectric composite sensors, combining piezoelectric Pb(Zr,Ti)O3 powder with a polymer matrix, are prepared and compared to existing...

Although Tangible User Interfaces are considered an intuitive means of human-computer interaction, they oftentimes lack the option to provide active feedback. We developed ‘Sensators’: generic shaped active tangibles to be used on a multi-touch table. Sensators can represent digital information by means of ‘Sensicons’: multimodal messages...

Complex planning tasks require substantial cognitive resources. Supporting planning tasks through enabling embodied interaction and providing multisensory feedback may reduce the cognitive load. We developed Sensators: interactive tangible objects to be used on multi-touch tables which provide both. In our demonstration, the user can experience...

Researchers have reported that audiovisual object presentation improves memory encoding of object identity in comparison to either auditory or visual object presentation. However, multisensory memory effects on retrieval, on object location, and of other multisensory combinations are yet unknown. We investigated the effects of visuotactile...

Brain Computer Interfaces (BCIs) rely on the user's brain activity to control equipment or computer devices. Many BCIs are based on imagined movement (called active BCIs) or the fact that brain patterns differ in reaction to relevant or attended stimuli in comparison to irrelevant or unattended stimuli (called reactive BCIs). Traditionally BCIs...

Touch is an essential channel in interpersonal and affective communication, yet most social agents currently lack the capability to touch the user. In this paper we show the credibility of three premises that make the case that providing touch capability to social robots will increase their effectiveness in communicating emotions, building trust...

This paper presents an experiment in which people performed a co-design task in urban design, using a multi-user touch table application with or without interactive model simulations. We hypothesised that using the interactive model simulations would improve communication and co-operation between co-design participants, would help participants...
