User Study on Collaborative Work 1.6.2011
This video shows excerpts of an extensive experimental user study that provides a rich understanding of the influence different interface types (reality-based versus PC-based) can have in a collaborative information seeking situation.
More information on the subject can be found here. The paper appeared in the INTERACT 2011 proceedings.
Meet Me in the Library! 1.3.2010
A vision of the library of the future enabling co-located, collaborative information-seeking.
When looking at the information-seeking process proposed by many theoretical approaches, collaboration plays an important role. Unfortunately, todays information seeking systems generally do not support co-located, collaborative work very well. One major problem is that commonly used hardware like PCs, laptops or terminal computers, operated by mouse and keyboard, give little opportunity to support multiple users at the same time. Therefore, the concept shown here proposes a new way to interact with an information system by using multitouch technology and tangible user interfaces.
Weighted Boolean Filter Queries 1.12.2009
A concept that shows how weighted boolean filter queries can be formulated using tangible user interface elements (the Search Tokens). The Search Tokens enable co-located, collaborative information-seeking.
To use the Search Tokens, place a token on the tabletop display, enter a filter keyword with the onscreen keyboard and then change the weight of this filter by turning the token like a volume knob of a stereo. Turning it to the right will enlarge all matching objects, turning it to the left will decrease their size.
Query by Example 1.11.2009
A concept that demonstrates how real-world objects like a DVD can be used to search for similar content in a digital information system.
When a DVD is placed on the tabletop display, a visualization shows up, where the user can select actors and directors of the movie. This selection is the input for a new query to the information system and brings other movies with these persons in it to the user's attention by scaling up their size.
Search, Explore and Navigate 1.4.2009
A concept of a zoomable user interface to search, explore and navigate through information. Movie data objects are used to showcase the concepts.
Multiple Display Environments 1.12.2008
Some early implementations of a multi display environment setting that supports users in their information-seeking process. The wall displays are synchronized with the tabletop display.
Multitouch technology is used to interact with the tabletop display. The wall displays are operated by an infrared laser pointer.
