Internet of Things (IoT) IoT is a concept of extending internet connectivity beyond conventional computing platforms such as personal computers and mobile devices, and into any range of tangible non-internet-enabled physical devices and everyday objects.
Wearable Tech Smart electronic devices that can be incorporated into clothing or worn on the body as implants or accessories.
E-Textiles E-textiles are fabrics that enable electronics to be embedded in them, providing added value to the wearer. Smart fabrics can communicate, transform, conduct energy and even grow.
Body-Centric Interaction Body-Centric Interactions is a novel field of interaction design that extends a device’s interaction space from the screen to the users body. It provides users with alternative off-screen interaction possibilities. Body-Centric interfaces are displays, wearable devices, or garments that en- able body-centric interactions.
25 min activity Please discuss in pairs and then draw (at least 2 sketches per person) future wearable prototypes and then present it to class. You may draw not only a sketch of the prototype but also a brief use case scenario.

Research Problem • Body-centric vibrotactile interfaces that can communicate information on a subliminal level of human perception. • Plenty of research in HCI investigates how various vibro-tactile stimuli may simulate sense of presence. Most of these studies work in the plane of conscious or explicit perception of stimuli and few touch upon the implicit or unconscious perception.
Research Goal To clarify how a range of vibro-tactile displays can be used to convey information through unconscious perception in body-centric configurations.
Current Goal To design a vibro-tactile prototype for enabling future experiments to investigate how parameters need to be configured to evoke experiences of haptic stimuli on a conscious versus unconscious level. Parameters: frequency, amplitude, intensity, duration, location on the body.
Current Research Question What configurations of parameters of a vibro-tactile display are more effective and efficient in communicating information on an unconscious level for a specific context?
15 min Task In pairs, please discuss the potential use cases for vibro-tactile wearable interfaces that may communicate information on a subliminal level of perception. Consider your areas of research.
Research Context Sense of presence in a remote relationship
Methodology A controlled set of experiments to test how various configurations of vibro- tactile displays alter the perception of a user on a continuum of conscious vs unconscious. Psychophysics + Existing Tactile Algorithms + Signal Detection Theory
Methodology • Vibrotactile Design space maps to the psychological space; • Signal Detection theory, haptic priming; • To predict the probability of the person capturing the stimuli (hit/miss).
Future Work RQ: to what extent can vibro-tactile body-centric distributed displays support a “peripheral” (unconscious perception) style of interaction? Methodology: Set of experiments to test affective states, and possibly longitudinal study in natural setting.
Foreseen Challenges • Correctly simulate needed sensations while communicating it on an unconscious level; • Design an experiment to measure stimuli on an unconscious level.
Societal Considerations The opportunities are endless but • Technology, enabling unconscious communication, may potentially be used in “nudging” scenarios; • Privacy issues; • Potential health implications; • Impact on the environment.
