The evaluation showed that the specific dBoard features were all found very useful, with the videoconferencing as a significant high score. During the interviews, several issues and suggestions for improvements were raised by the participants. A recurrent question was related to ‘information overload’,
i.e. what happens if too much Scrum information is shown on the dBoard display? Is there a risk of covering most of the video? Another line of comments was related to the usage of proxemics. Several participants mentioned that they would prefer to have the de-blurring of video triggered by the knock-knock feature rather than the proxemic interaction.
This later issue relates to whether blurring – or any other feature – should be based on implicit (proxemics) or explicit interaction. This limited study shows that users tend to prefer explicit gestures for initiating (de-blurring) a video meeting, whereas automatic blurring the video once users is no longer in front of dBoard seems to be feasible. However, studying the pros and cons of implicit interaction in dBoard would require a longer deployment study.
