In this article we present Tuio, a simple yet versatile protocol designed specifically to meet the requirements of table-top tangible user interfaces. Inspired by the idea of interconnecting various existing table interfaces such as the reacTable* [1], being developed in Barcelona and the tDesk [2] from Bielefeld, this protocol defines common properties of(More)
Motivated by the need to better manage energy demand in the home, in this paper we advocate the integration into Ubicomp systems of interactive energy consumption visualisations, that allow users to engage with and understand their consumption data, relating it to concrete <i>activities</i> in their life. To this end, we present the design, implementation,(More)
Mobile devices are generally used in public, where the user is surrounded by others not involved in the interaction. Audible notification cues are often a cause of unnecessary disruption and distraction both for co-located people and even for the user to whom they are directed. We present a wearable peripheral display embedded in eyeglasses that delivers(More)
Mobile communication devices, such as mobile phones and networked personal digital assistants (PDAs), allow users to be constantly connected and communicate anywhere and at any time, often resulting in personal and private communication taking place in public spaces. This <i>private -- public</i> contrast can be problematic. As a remedy, we promote(More)
Using a mobile device in a social context should not cause embarrassment and disruption to the immediate environment. Interaction with mobile and wearable devices needs to be subtle, discreet and unobtrusive. Therefore, we promote the idea of "intimate interfaces": discrete interfaces that allow control of mobile devices through subtle gestures in order to(More)
Future energy systems that rely on renewable energy may bring about a radical shift in how we use energy in our homes. We developed and prototyped a future scenario with highly variable, real-time electricity prices due to a grid that mainly relies on renewables. We designed and deployed an agent-based interactive system that enables users to effectively(More)
Rather than merely imitating the desktop metaphor for mobile devices, new interface paradigms that take into account the particular characteristics of mobility, need to be developed. In this paper an input device based on the electromyographic (EMG) signal is proposed as a controller for mobile interaction. The interface can be considered subtle or intimate(More)
Visual markers are graphic symbols designed to be easily recognised by machines. They are traditionally used to track goods, but there is increasing interest in their application to mobile HCI. By scanning a visual marker through a camera phone users can retrieve localised information and access mobile services. One missed opportunity in current visual(More)
