RFID-driven situation awareness on TangiSense, a table interacting with tangible objects

Abstract

International audienceInteractive tables are increasingly present not only in a research context but also in everyday life. One challenge still has to be taken up concerning interaction with several people around an interactive table. The framework of our research relates to an interactive table named TangiSense, which is equipped with RFID technology. The interaction is no longer the result of touching the table, but comes from handling tangible objects placed on the table. The use is closer to the natural use of a table. This technology makes it possible to identify the objects, which can be coupled with the users. Starting from this principle, the article proposes the use of RFID tags to collect the elements of context awareness in order to adapt the workspaces to the various possible situations around a table (work alone or with several users, on a common or individual space). An algorithm of space division is proposed, and evaluations are carried out in order to assess its global contribution. The article ends with a conclusion and some prospects

“…This system could be used to implement serious games to simulating money, transactions, badges or roles in schools. Indeed, RFID technology has been previously experimented supporting the simulation of roles and scenarios on interactive tables [32]. As result of this experience, the authors highlight RFID as an interesting approach as they allow the storage of information directly within the tangible objects.…”

Implementation of the stroop task using an interactive table

“…The tiles are associated with a control interface connected to the host computer by an Ethernet link. For more details, the reader can see [4].…”

“…Information can be conveyed via a variety of modalities. Vision, touch, and sound can serve as stimuli [4]. Designers of interactive tables and applications are thus disposed to choose the optimal combination of information streams.…”

“…We have implemented this version using an interactive table, called TangiSense. This table and its software architecture are described in [4]; several hardware characteristics are provided in the next section. Due to a lack of space, the implementation is described in this paper only through illustrations and their associated explanations (see Figure 1 and Figure 2).…”

“…Most commercial interactive tables inspired by the former surface by Microsoft are provide reliable user input [24]. They usually use computer vision, or RFID tags like the Tangisense [9]. HP proposed a hybrid computer -interactive projection in late 2014 [6].…”
