My group is pursuing a vision of reactive interior spaces which are aware of people’s actions and transform according to changing needs. We envision furniture and walls that act as interactive displays and that shapeshift to the correct physical form, and the appropriate interactive visual content and modality. This talk illustrates the recent efforts toward realizing our vision.(Read more...)
Midair haptics enabled by non-contact ultrasound haptic stimulation provides new tools of computer interfaces. A key issue of midair haptics is to find the best mix of haptic feedback and visual/auditory one each of which complements the others. Visual feedback to a user is effective for transmitting spatial patterns and sounds from a user can concisely specify the intentions. In this talk, I will show recent examples of midair haptics with visual feedback and discuss future possible combination with other modalities.(Read more...)
Electro Muscle Stimulation (EMS) provides rich opportunities for computer human control. Recently, EMS has been used in HCI to provide muscle-propelled force feedback and walking directions, to confer affordances and to share muscle control, for example. Due to individual physiological differences, these EMS systems require time-consuming, manual, per-participant calibration. Furthermore, existing approaches have relied on large-size, uniform-shape electrodes that make targeting specific muscles difficult and result in unwanted movement artefacts. As a result of this requirement for calibration, existing research has typically relied on limited, gross-movement stimulation gestures, such as rotations of the wrist or leg.
In this talk, I will present our ongoing work on auto-calibrating EMS through muscle signal repetition; reading muscle activation patterns with electromyography (EMG) and writing back with EMS. We use EMG to infer locations of key muscle activity and use this to drive complex, multi-electrode, multi-channel stimulation. I will present our control system for an electrode-dense wearable sleeve that enables pose-aware, complex and natural gestures, and discuss future research opportunities in this space.(Read more...)
My background is in design and HCI. I have a long-standing interest in understanding how designers’ intentions are challenged as a consequence of users’ values, needs and appropriation of technologies. Examples of work in this area include identity construction through avatars, location tracking in families, and social network use.A second strand of work is centred on design thinking. This has enabled me to understand challenges, such as the need for privacy awareness, from a different perspective than that typically taken.I have been also exploring the notion of user participation in design more generally in light of the expectations that TEL must fulfil, the real world constraints faced during design research and the multidisciplinary teams involved in TEL projects.(Read more...)
International projections suggest that mental illness will become the leading cause of disability worldwide in the coming decades. Difficulties such as depression currently account for 13% of all lost years of healthy life globally, rising to 23% in high-income countries. In light of these findings urgent calls have been made for innovative new approaches to improve mental health care services. Young people have been identified as particularly vulnerable and requiring specific attention. This talk will consider the role that technology-enabled mental health services can play in helping to address this challenge. It will be grounded in recent research on the design and evaluation of integrated systems – incorporating computer games, mobile apps and online services – to support mental health interventions for young adolescents.(Read more...)
