We present tools for prototyping and for testing wearable computing applications. The hardware platform consists of a mobile phone and a custom-built box, which can be equipped at runtime with different sensors and actuators. Software libraries for signal processing and classification complement the toolkit. Users without expertise in electronics or in signal processing can quickly create fully functional wearable prototypes that sense human motion and trigger tactile feedback as response to specific postures in real-time.

We present a study which evaluates the use of simple low-power sensors for a long-term, coarse-grained detection of sleep postures. In contrast to the information-rich but complex recording methods used in sleep studies, we follow a paradigm closer to that of actigraphy by using a wrist-worn device that continuously logs and processes data from the user. Experiments show that it is feasible to detect nightly sleep periods with a combination of light and simple motion and posture sensors, and to detect within these segments what basic sleeping postures the user assumes. These findings can be of value in several domains, such as monitoring of sleep apnea disorders, and support the feasibility of a continuous home-monitoring of sleeping trends where users wear the sensor device uninterruptedly for weeks to months in a row.

We present PianoTouch, a wearable, wireless haptic piano instruction system, composed of (1) five small vibration motors, one for each finger, fitted inside a glove, (2) a Bluetooth module mounted on the glove, and (3) piano music output from a laptop. Users hear the piano music and feel the vibrations indicating which finger is used to play the note. We investigate the system's potential for passive learning, i.e. learning piano playing automatically while engaged in everyday activities. In a preliminary study, four subjects learned two songs initially and then wore the PianoTouch glove for 30 minutes while listening to the songs repeated. One of the songs included tactile sensations and the other did not. The study found that after 30 minutes, the PianoTouch subjects were able to play the song accompanied by tactile sensations better than the non-tactile song. These results suggest the value of a more detailed study.

A mobile gesture-controlled speech synthesis system raises various design and aesthetic issues and problems. Solutions must help create speech/song as effectively and expressively as possible, while still promoting the aesthetic vision of the clothing. This technology will allow users to expand their range of artistic expression, allowing them to Walk the Walk, and Talk the Talk.

Wearability, or the relationship between a worn technology and the ability or desire of the user to wear it, is a key element in the successful design of wearable technologies. Wearability addresses the physical, cognitive, and emotional state of the user, and the impact of the wearable technology on the user's homeostasis in each area. This tutorial will provide the participant with an overview of the pertinent variables and design considerations for the design of truly wearable technologies. We will address factors related to anatomy, ergonomics, cognitive science, psychology, sociology, textile science, interface design, and apparel design.

For an effective design of ECG shirt, clothing pressure in each point with a shirt composed of 60% polyester, 33% cotton, and 7% Lycra was measured, and the qualities of ECG signals with the textile-based electrodes on the shirts according to contact capacity were compared. A clothing pressure measuring device developed for stationary state was used in the experiment to quantitatively analyze clothing pressure, and the ECG signal detection rates of the textile-based electrodes according to the regions where they were attached were calculated. Five subjects were participated in the experiments, and their clothing pressures were measured in 30 points in their upper body in 3 postures. The results showed a high degree of correlation between clothing pressure and ECG signal detection rate regardless of the subject's postures.

This workshop will provide a forum to discuss the role of design in wearable computing. Wearable computing spans a broad range of interests and expertise, not all of which can be adequately represented by a technical paper in an IEEE Computer Society proceedings. As wearable computing becomes more mainstream and if it is to continue becoming more mainstream, it is important for ISWC to provide appropriate venues for presenting the latest advances in textile, fashion, and industrial design. The objective of this workshop is to come up with a set of recommendations on what the appropriate venues should be and to discuss what the important design issues are for wearable computing.

We show how a system for video-rate parallel camera tracking and 3D map-building can be readily extended to allow one or more cameras to work in several maps, separately or simultaneously. The ability to handle several thousand features per map at video-rate, and for the cameras to switch automatically between maps, allows spatially localized AR workcells to be constructed and used with very little intervention from the user of a wearable vision system. The user can explore an environment in a natural way, acquiring local maps in real-time. When revisiting those areas the camera will select the correct local map from store and continue tracking and structural acquisition, while the user views relevant AR constructs registered to that map.

In contrast to infrastructure supported location systems, relative positioning technology identifies the relative position of objects to each other solely based on local sensors and processing only. This tutorial provides background and hands-on experience over sensor technologies and modalities, measurement principles, systems, distributed algorithms and applications for relative positioning technologies. It will also give hands on insight to relative positioning using the RELATE relative positioning sensor network platform as an example. The tutorial will also discuss other practical issues as price, constraints for integration and use of relative positioning technology. The tutorial will be suitable also for people not familiar with positioning systems, algorithms and hardware.

We demonstrate how modulated magnetic field technology that is well established in high precision, stationary motion tracking systems can be adapted to wearable activity recognition. To this end we describe the design and implementation of a cheap (components cost about 20 Euro for the transmitter and 15 Euro for the receiver), low power (17 mA for the transmitter and 40 mA for the receiver), and easily wearable (the main size constraint are the coils which are about 25 mm3) system for tracking the relative position and orientation of body parts. We evaluate our system on two recognition tasks. On a set of 6 subtle nutrition related gestures it achieves 99.25% recognition rate compared to 94.1% for a XSense inertial device (operated calibrated, euler angle mode). On the recognition of 8 Tai Chi moves it reaches 94 % compared to 86% of an accelerometer. Combining our sensor with the accelerometer leads to 100% correct recognition (as compared to 90% when combining the accelerometer with a gyro).
