Low-Cost Sensors and Biological Signals

Many sensors are currently available at prices lower than USD 100 and cover a wide range of biological signals: motion, muscle activity, heart rate, etc. Such low-cost sensors have metrological features allowing them to be used in everyday life and clinical applications, where gold-standard material is both too expensive and time-consuming to be used. The selected papers present current applications of low-cost sensors in domains such as physiotherapy, rehabilitation, and affective technologies. The results cover various aspects of low-cost sensor technology from hardware design to software optimization

Gestural patterns: a new method of printed textile design using motion capture technology

The aim of this research is to develop a new method, Hybrid Printing System (HPS) to explore digital craft methods to create surface patterns for printed textile design. This novel method of creating ‘handcrafted’ prints is a result of the integration of two technologies such as motion-capture (MOCAP) and digital textile printing (DTP). The research towards such an innovation required a current, historical, contextual and experimental study of use of motion capture in Art &Design. The research contextualises the hand and its relationship to digital crafting methods in printed textile design, the digital medium and the process of audience participation in printed textile design to create a new conceptual framework balanced in practice and theory. The practical research then develops three new methods of motion capture such as, motion tracing, motion sensing and motion tracking to generate gestural motifs and gestural patterns. This thesis and the accompanying set of experimental work demonstrates that HPS culminates in developing new aesthetics through a new mode of creation in a new medium, which will impact the user, the designer and the product as a part of the cyclical process. HPS is an advancement of printed textile design, centred in active participation of its audience at the generative stage of design. This results in a shifting role of a designer and subverts the current model of printed textile design practice. HPS is a democratic design process where the participants design for themselves, have their own voice, which induces a sense of community, togetherness and harmony in the creative process

Spatial Displays and Spatial Instruments

The conference proceedings topics are divided into two main areas: (1) issues of spatial and picture perception raised by graphical electronic displays of spatial information; and (2) design questions raised by the practical experience of designers actually defining new spatial instruments for use in new aircraft and spacecraft. Each topic is considered from both a theoretical and an applied direction. Emphasis is placed on discussion of phenomena and determination of design principles
