ActiveShare: sharing challenges to increase physical activity

2008: 3-month design case for Philips Research.

active_picGoal: Designing and testing a persuasive technology concept to increase the physical activity of sedentary office workers.

Process: Literature study, user studies, several design iterations of prototyping, user testing, and re-designing, a final implementation, and a three-week user evaluation.

active_vidResults: The ActiveShare concept (video on Vimeo) with many valuable user data, and a publication at CHI 2009 in Boston (paper at ACM).

AugNav: Augmented Reality Navigation

2008: 1-week design project on multi-modal perception with Jim Juola.

augnav_picGoal: Design or re-design a daily product using the user’s multimodal perception.

Process: Brainstorming, sketching, and video prototyping.

augnav_vidResult: Based on next generation mobile phones with GPS, a camera, and fast internet, we came up with an augmented reality navigation concept, using the camera’s live footage to augment navigation information on. We also envisioned automated detection of road signs. (Read more)

Philips Amigo Extended Home

2008: 3-week UX evaluation study for Philips Research.

amigo_picGoal: User testing the Philips Extended Homes project, part of the EU-project Amigo on ambient intelligence.

Process: We connected two living rooms with an interactive TV, digital photo frames, lights and a social robot. 40 test users performed several tasks, while being observed and interviewed afterwards.

amigo_vidResults: Results of the interviews were analysed and transformed into an extensive design recommendations report. Have a look at our video report.

Wii Multiplayer: Friends or Foes

2008: 3-week observation study with Emiel Krahmer and Marc Swerts.

wii_pic_0 Goal: Measure emotional engagement in a multiplayer game on the Nintendo Wii, to decide what is more engaging: cooperative (together against a computer) or versus (against each other).

Process: Observation of non-verbal behaviour by observation rating techniques, similar to this paper.

wii_pic_1Results: Participants played tennis in two conditions. Their observation videos were rated by a second group of participants. We statistically analysed differences across cooperative/versus and won/lost conditions.

Context Awareness in Ambient Intelligence Surroundings

2007: 9-month research project for Philips Research.

shopwindow_picGoal: Design a context awareness model for the intelligent interactive shopping window of an ambient intelligence project in the Philips ExperienceLab.

Process: Finding requirements by a literature study, scenario analysis, and brainstorms. Designing, developing, user testing, and integrating with existing applications.

shopwindow_vidResults: A compact hierarchical model representing context data was developed, tested and proven to be highly expressive and robust.
