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.

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.

By pressing the button, users can execute specialized functionalities on their mobile phones, e.g. dialing phone numbers or accessing URLs. We present three usage scenarios and a proof-of-concept prototype.

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.

It follows a simple approach, lighting one LED for each hour of sleep, and physically resembles the interaction with a conventional hourglass: Tilting the hourglass moves 'time' between its chambers, placing it in an upright position activates it, turning it by 180° snoozes it and placing it horizontally on a surface turns it off.

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.

The alteration of shape is implemented in a hardware prototype using a dynamic knob as an interaction device for the user. The knob alters the phone's shape according to different events and states, like incoming calls, new voice mail, or missed calls. Therefore, the user can explore the phone's status by touching it - ambiently, even through the pocket. Initial user testing showed that this form of tactile interaction was easy to understand and handy to interact with, also for unexperienced users.
