Usability Test User testing was conducted with two different prototypes to research possible preferences between distinct functionalities that would shape the final iteration. The primary goal of the usability test was to clarify which level of traditional planning was preferred within a family setting. The assumption that no planning was necessary, was represented by the radar concept where family members do things together entirely based on opportunities that arise in the moment. The planning concept incorporated a minimum of planning functionality: Letting the users agree on only a day for a gettogether. Secondary objectives of the user test were to obtain feedback on interactive elements such as the cognition-based feedback and feedforward represented by the pointing LEDs of the LED ring, the colors, the bumping surface - including the animation that conveyed agreement - and the charging of the family bond. The ability to hide oneself from the system was also investigated. The complete testing protocols can be found in Appendix E and F.

Findings The experiments were recorded, transcribed (Appendix G) and important feedback was extracted. In order to make sense of this qualitative data, the “download method” was applied (IDEO [2], 2018). The essence of the method is to group obtained knowledge by themes in order to spot patterns in the data.
