Yesterday I blogged about a poster and a conference paper that Emma Frid and I developed for the SweCog conference in Uppsala. In this post I will focus on the second poster and paper that Eva-Lotta Sallnäs Pysander and I developed for the same conference.
The poster shown in the picture above, and even more so the paper, summarizes some of the main points made from my doctoral studies. My main focus during those years was collaboration in multimodal virtual environments with special emphasis on how haptic feedback can be used for communicative purposes. Mediated haptic communication has been studied for quite some time, but my specific contribution here has been to develop and test new functions for two-way haptic communication (see short descriptions of the functions on the poster) and also adapt some already developed ones in order to make them work better in a situation when a sighted person is collaborating with a severely visually impaired one in a collaborative virtual environment. There is a real potential in these kinds of functions when it comes to collaboration between sighted and visually impaired – the haptic feedback does not only enable establishment of a common ground about the interface but also effective two-way communication (see examples of results on the poster above). This is very important for the inclusion of visually impaired persons in group work. The example study is reported in much more depth in this article.
Even though the poster and paper include summaries of work already performed and reported, we are in this case even more explicit about the connection to other kinds of haptic communicative functions. This conclusion also takes the work to the next level:
We argue that for effective collaboration and communication to take place in virtual environments by means of haptic feedback the haptic functions need to be designed as to allow for reciprocal exchange of information. That is, both users need continuous feedback from each other during e.g. a guiding process or joint object handling.
The conference paper, on which the above poster is based, can be found here.
