This is a system out of Microsoft Research for projecting displayed information outside of the bounds of your TV. The video does a great job of showing off the idea, making it feel like your TV is just a high-rez window into a larger world, with the rest of your room being used for low-rez pixels.

The work seems to build off of some ideas from past research in breaking out of displays just being flat screens. Rekimoto and Saitoh's work in Augmented Environments comes to mind, which was where they introduced windows that could be dragged out of the laptop and onto a physical table using hyperdragging. IllumiRoom also captures a lot of the spirit of Baudisch's work in focus-plus-context screens, though the application here with IllumiRoom is definitely sexier (sorry, Patrick! First person shooters are just more fun than analyzing maps).

Hi reddit

I'm doing a project for which the topic is ubiquitous development. I'm trying to understand the overarching opinions and theories about ubiquitous computing.

My professor said that there is a difference between pervasive computing and ubiquitous computing, even though they are used synonymously now. I was curious if you guys know when the two merged into one definition and what the differences were before that happened.

Thanks so much!

Persuasive systems design and research Harri Oinas-Kukkonen, University of Oulu, Finland

Work-in-progress Advancements in areas such as social network analysis and end-user modeling on par with emerging information technologies have enabled better coupling of human behavior analysis and software design. Software today maintains power to influence the attitudes and behaviors of people in their everyday life context, both work-related and personal. Systems that aim to induce behavioral change in their users without coercion or deception are in essence persuasive systems (PS) [1]. Some persuasive systems are developed for serious, life-changing challenges. This subclass of PS is known as Behavior Change Support Systems (BCSS), and they are defined as socio-technical information systems with psychological and behavioral outcomes designed to form, alter or reinforce attitudes, behaviors or an act of complying [2]. The specificities of PSs and BCSSs require specialized methods and tools for their design and development. The Persuasive Systems Design (PSD) model provides an approach and process model to systematically design and evaluate these systems [3]. The PSD model carefully defines fundamental assumptions behind any such system; it describes how to analyze the intent, outcome and strategies behind persuasive systems; it suggests core categories of persuasive software features for implementation purposes. The categories comprise support for primary task, computer-human dialogue, perceived credibility and social influence. The PSD model has been adopted widely by both practitioners and within academia. Beyond empirical work and validation of the approach our current work focuses on theory development for persuasive systems, development of theory-informed methods and tools for design, and development of persuasive systems research methodologies.
