In contrast to a lot of the research in the field of affective computing our project is not dedicated to enable machines to detect human emotions but to allow new input methods. This demo presents 'MyInnerLife', a physical input device to express and record emotions non-verbally.

It can be stressful to keep all the measured values under control when pursuing this ambitious way of life. Body weight can be an especially emotional issue for many people and slight differences can be perceived as lack of discipline, although little fluctuations are natural. In this paper, we present a tangible display for body weight, based on floor rigidity. It displays body weight without numbers, which makes it less suitable for comparisons, while still giving the user an idea about their weight. We describe the metaphorical foundations of the concept, as well as the development of two prototypes, which implement the envisioned full-body weighing experience. We demonstrate how the design of a display can influence the users' connotation of data.

A1 - Urban, Bodo A1 - Wettach, Reto T1 - Exploring vibrotactile feedback on the body and foot for the purpose of pedestrian navigation T2 - iWOAR '15 : Proceedings of the 2nd international Workshop on Sensor-based Activity Recognition and Interaction N2 - In this paper, we present an evaluation of vibrotactile onbody feedback for the purpose of pedestrian navigation. For this specific task, many researchers already provide different approaches such as vibrating belts, wristbands or shoes. Still, there are issues left that have to be considered, such as which body position is most suitable, what kind of vibration patterns are easy to interpret, and how applicable are vibrotactile feedback systems in real scenarios. To find answers, we reconstructed prototypes commonly found in literature and continued to further evaluate different foot-related designs. On the one hand, we learned that vibrotactile feedback at the foot reduces visual attention and thus also potentially reduces stress. However, on the other hand, we found that urban space can be very diverse, and ambiguous and therefore a vibrotactile system cannot completely replace common path finding systems for pedestrians. Rather, we envision such a system to be applied complementary as an assistive technology.

Through a servo motor construction, it is enabled to move and behave in life-like manners and to step into dialogue with the user. For example about water consumption or hygiene. We sought to research the reactions of users to such an appliance, alongside possible implications for the design of future human-machine interfaces. This project is part of a larger series of experiments in the Living Interfaces project, exploring ways in which reduced and abstract life-like movements can be beneficial for Human-Machine Interaction.

However, as these prototypes are generally constructed using solder-free technologies, they are often fragile and unreliable. This means a huge burden of care and upkeep for these inventions when they are either exhibited or sold. We present a software application called Fritzing which allows artists, designers and DIY-tinkerers to prepare their hardware inventions for production. Through an interface metaphor based on the typical workflow of the target group, Fritzing has proven its ability to provide useful support in the steps following the invention of an interactive artifact. Fritzing serves also as a tool for documenting these interactive artifacts. As sharing of knowledge has been a driving force within this new DIY-movement, there is a need for a consistent and readable form of documentation which Fritzing can provide. Fritzing has also proven to be a useful tool in teaching electronics to people without an engineering background.

However, the entry of textual pain data may be negatively reinforcing, due to its character of direct confrontation with one's pain, potentially leading to a higher pain awareness. This paper introduces valeo, a new form of a tactile pain log, which is based on a vibrotactile, pressure- and tilt-sensitive device. Future iterations will also include body part recognition. By squeezing it close to one's own body, the subjective intensity of a local pain is manifested in the device. Via a shove gesture, it is then transmitted to a docking station. Advantageously, the pain data is covert and conceptually alienated from the patient's body, which may support a possible relief. A proof-of-concept prototype and a user study indicate that our concept is perceived as convenient and reduces negative conditioning.

This project sought to explore life-like behaviour as a means of increasing user's sympathy for everyday objects. We present a prototype that was informally tested with six participants in a situated user test. The results indicate that sympathy and perceived cuteness can arise from life-like movements that, as we propose, represent an object's will of its own. This work is part of a larger series of experiments in the Living Interfaces project, exploring ways in which reduced life-like movements can be beneficial for Human-Machine Interaction.

The Intimate Door Lock investigates the psychological effects of intimate humanhuman interaction being applied to man-machine interfaces. The door lock, in our prototype, is installed at the inside of a domestic front door, and remains locked until given a kiss by its owner. In our prototype, the element to be kissed is a camera-augmented mirror, which we intended to use as a means of lowering the inhibition level. This work is part of a larger series of experiments in the Living Interfaces project, exploring ways in which reduced life-like movements can be beneficial for Human-Machine Interaction.

In the following, we describe a system that adds a new modality to computer-supported text editing: Listening with closed eyes. We present a prototype, for which we combined a text-to-speech software, Microsoft Word and a face tracking system. It reads out the current sentence in Microsoft Word as soon as the user closes both eyes. In this paper we discuss further details of the concept and its background, describe the implementation of the prototype and disclose first user testing results, before we conclude our findings with an outlook on future research.

While a synchronous exchange of factual information over distance is supported by telephone, e-mail and chat-systems, the transmission of nonverbal aspects of communication is still unsatisfactory. Videocalls let us see the partners' facial expression in real time. However, to experience a more intimate conversation physical closeness is needed. Stroking while holding hands is a special and emotional gesture for couples. Hence, we developed a device that enables couples to exchange the physical gesture of stroking regardless of distance and location. The device allows both sending and receiving. A user test supported our concept and provided new insights for future development.

While some widespread and well-recognized haptic displays such as force-feedback often trigger the user's immediate attention, we will focus on ambient strategies for tactile information display, that is, the display of gradual state changes in the user's periphery that do not unexpectedly interrupt her current tasks, but builds on the mind's ability for subliminal perception of environmental change instead [1, 2]. To this end, we present a series of prototypes of mobile devices that display ambient information by means of thermal change based on the thermo-electric effect [3]. In order to assess the expedience and feasibility of such a display, a series of user tests have been conducted with respect to both, the ability for thermal change recognition and a concrete application scenario for such a display.

Each ring can measure the wearer's heartbeat and send it to the partner's ring. Hereby, artificial corporeality is created between the couple. By means of a working prototype, united-pulse has been successfully tested. Among the 28 participants the prototype has attracted large interest. Through the heartbeat - the essential vital sign - a feeling of being very close to the partner is provided. Touching the ring allows a small moment of intimacy in situations where emotional support is needed.

A physical brush on a canvas acts as the instrument. The characteristics of its stroke are intuitively mapped to a conductor program, defining expressive parameters of the tone in real-time. Two different interaction modes highlight the importance of bodily expression in making music as well as the value of a metaphorical visual representation.
