In this paper we investigate the expression of emotions through mediated touch. Participants used the Tactile Sleeve for Social Touch (TaSST), a wearable sleeve that consists of a pressure sensitive input layer, and a vibration motor output layer, to record a number of expressions of discrete emotions. The aim was to investigate if participants could make meaningful distinctions in the tactile expression of the emotions.

In this paper we outline the design process of TaSST (Tactile Sleeve for Social Touch), a touch-sensitive vibrotactile arm sleeve. The TaSST was designed to enable two people to communicate different types of touches over a distance. The touch-sensitive surface of the sleeve consists of a grid of 4x3 compartments filled with conductive wool. Each compartment controls the vibration intensity of a vibration motor, located in a grid of 4x3 motors beneath the touch sensitive layer. An initial evaluation of the TaSST was conducted in order to assess its capabilities for communicating different types of touch.

PROMPT is a tactile-kinesthetic approach for assessment and treatment of speech production disorders. PROMPT uses tactile-kinethetic cues to facilitate motor speech behaviors. Therapy is structured from basic motor speech patterns with much tactile-lkinesthetic cueing, towards complex motor speech activities with less cueing. This article describes the purpose and contents of PROMPT assessment and therapy.

In this paper we present the concept and initial design stages of the TaSST (Tactile Sleeve for Social Touch). The TaSST consists of a soft pressure-sensitive input layer, and an output layer containing vibration motors. A touch to ones own sleeve is felt as a vibration on the sleeve of another person. The idea behind the TaSST is to enable two people to communicate dierent types of touch at a distance. We will outline the design process of the TaSST, describe some initial results from a user study, and discuss possible applications of the TaSST.

In this article I explore a perspective that the philosophical concepts of German phenomenologist Hermann Schmitz (*1928) may open up for thinking about the growing practice of wearing textile integrated electronics directly on the body. It is my contention that traditional conceptions of wearing (non-technological) clothing on the body fail to capture the changed situation and I hence suggest a paradigm shift is needed to think about the novel scope of affects that can be related to body-technology communication. Schmitz’s concepts of the perceptive felt body, corporeal communication and emotions as atmospheres perceived as outside, on or close to the ‘material’ body will be elaborated upon to investigate how they may enhance existing notions of bodily perception and human-technology relations. The case study used for this philosophical investigation is found in the Tactile Sleeve for Social Touch, a wearable created by Elitac, HvA and UTwente, which allows sensations of stroking, tapping and touching to be communicated from one person to another across a distance.

The Rollz Motion Smart rollator detects posture, gait and activity of a user and provides feedback. • Various programs to train the user and optimize walking performance. • Measuring gait parameters like velocity, step time, step length, distance between person and rollator. • Visual, tactile and auditory cues help the user to take the first step or maintain a suitable walking rhythm.

People with a visual impairment (PVI) often experience difficulties with wayfinding. Current navigation applications have limited communication channels and do not provide detailed enough information to support PVI. By transmitting wayfinding information via multimodal channels and combining these with wearables, we can provide tailored information for wayfinding and reduce the cognitive load. This study presents a framework for multimodal wayfinding communication via smartwatch. The framework consists of four modalities: audio, voice, tactile and visual. Audio and voice messages are transmitted using a bone conduction headphone, keeping the ears free to focus on the environment. With a smartwatch vibrations are directed to a sensitive part of the body (i.e., the wrist), making it easier to sense the vibrations. Icons and short textual feedback are viewed on the display of the watch, allowing for hands-free navigation.

Visually impaired people (VIP) can experience difficulties in navigating urban environments. They mostly depend on the environment’s infrastructure or technical solutions like smartphone apps for navigation. However apps typically use visual and audio feedback, which can be ineffective, distracting and dangerous. Haptic feedback in the form of vibrations can complement where visual and audio fall short, reducing the cognitive load.Existing research into wayfinding using haptic feedback to better support navigation for the visually impaired often relies on custom tactile actuators and the use of multiple vibration motors. Although these solutions can be effective, they are often impractical in every day life or are stigmatizing due to their unusual appearance.To address this issue we propose a more modular system that can be easily integrated in commercially available smartwatches. Based on existing research we present a tactile communication method utilizing the vibrotactile actuator of a smartwatch to provide VIP with wayfinding information that complements visual and audio feedback. Current smartwatches contain a single tactile actuator, but can still be used by focusing on navigation patterns. These patterns are based on research in personal orientation and mobility training with VIP. For example, a vibration pattern is used to represent a concept like ‘attention’, ‘left’ or ‘stairs’ directing the navigator’s attention towards audio or visual information or to the environment.In next phase of this research we will conduct several focus groups and co-creation sessions with VIP and orientation and mobility experts to further specify the requirements and test our proposed tactile method. In the future, this method could be integrated in existing navigation apps using commercially available devices to complement visual and audio information and provide VIP with additional wayfinding information via haptic feedback.

More and more information labels appear on the front of food packages, increasing the complexity of consumer decision-making and enhancing consumer scepticism toward food labels. It is important to evaluate the efficacy of information communicated to consumers. The experimental study among 209 Dutch consumers compared the effect of health and hedonic labels on consumer scepticism toward the labels and consumer responses to food products (apple juice and a chocolate cookie) under three presentation conditions (visual, visual-tactile and multisensory). The results demonstrated that consumers were more sceptical toward the hedonic label than toward the health label. The influence of consumer scepticism on product experience, product evaluation and purchase intention varied for different product categories. For a hedonic product (a chocolate cookie), the hedonic label had a more positive effect on consumer responses compared to the health label. The results also showed that the multisensory presentation reduced scepticism and enhanced product evaluation for the hedonic product compared to the visual and tactile presentations. The results suggest that multisensory experience may alter consumer scepticism toward food labels and thus product evaluation and consumer choice. Our findings can be useful for food manufacturers and policy makers in evaluating the efficacy of food labels and information presented on food packages.

We need mental and physical reference points. We need physical reference points such as signposts to show us which way to go, for example to the airport or the hospital, and we need reference points to show us where we are. Why? If you don’t know where you are, it’s quite a difficult job to find your way, thus landmarks and “lieux de memoire” play an important role in our lives.
