At three stations, participants were able to incorporate their feedback into the development. The usability of the app was tested by Dr. Julia Hoxha, who allowed the participants to freely discover how to use the smartphone application. Afterwards, the patient:s were guided through a feedback questionnaire. The planned speech exercises from the app could be tested on the spot with Marlene Kessler to find out whether the speech exercises and speech texts were too standardized or should encourage more variety and motivation.
At the last station, participants were able to try out cosinuss°’s vital signs measurement technology and track their vital signs on the screen. The first application without assistance was easy for most of the participants, as many of them have experience with hearing aids, for example, and are generally very technically proficient. There were differing opinions on when and how often the sensor should be worn, ranging from going to work to wearing it overnight. There were voices that would prefer the symmetrical wearing experience of two earbuds similar to headphones. Overall, the wearing experience was rated quite positively with words like “soft” and “cuddly”.
