Over the past few months we worked with 6 representatives of our target end-user group to collect information necessary for defining detailed requirements for the Insension system. Today we completed the last piece of data recording. Together with the assessment of the skills of the participants, these data will allow to verify the usefulness of known face expression, gesture, vocalization and physiological response technologies. The next step is the annotation of the recorded data in a way that enables the system to begin to ‘understand’ our end users. The participants of the study recruited from the Na Tak care centres: kindergarten “Orzeszek”, school “Zakątek” and adult care centre “Kamyk” (2 persons from each of the considered life stages).
