### Diary-Interview and Semi-Structured Interview Results: Wearable Technology User Experience
In Table 2, the frequency values are created to compare users' experience of the accessory-based wearable technology (chest band) and textile-based wearable technology (T-shirt) products. These frequency values showed that textile-based wearable technologies lead to more positive experiences overall, as shown in Figure 5 (abbreviations are shown in Table 2). In terms of wearability, the T-shirt had more positive experiences than the chest band. The T-shirt has more positive experiences in terms of fit (W1), mobility (W4), sensory adaptation (gradual decrease over time in the responsiveness of the sensory system to a constant stimulus) (W6), and thermal comfort (W5) compared to the chest band. Participants reported 21 positive experiences for the fit of the T-shirts during the process, compared to only 3 for the chest band. For thermal comfort, the frequency value of the T-shirt was 14, while the chest band was 1. When we compared the negative experiences, the chest band fit frequency value was 30 and the T-shirt fit frequency value was 11. While the negative sensory adoption chest band frequency value was 12, no negative experience was reported for the T-shirt. The most important reasons for this were that the chest band loosened and moved on the body, or squeezed the body and caused more sweat when worn tight. Users commented on this situation as \"I think it is designed to be a nuisance because it feels like someone is hugging me from behind\" or \"It was uncomfortable because the chest band made me sweat more\". The chest band, on the other hand, had advantages in terms of doffing and donning, because the T-shirt completely wrapped the body, causing difficulties for the users, especially when taking it off (\"On the first day, it was difficult to put on and take off, although the product fit my size. I got help from my wife in removing it\"). It is noteworthy that the chest band had the highest frequency of negative experiences in terms of tactile comfort (W3). While the participants did not express negative tactile comfort for the T-shirt, they stated 21 negative experiences for the chest band. Although this result is related to the material of the product, it shows that the product is not fully suitable for user mobility. Since the two products use similar technologies, there were no significant differences in usability, only users expressed negative experiences about the connection (Ub2) problems of the T-shirt. The reason for this was related to the applications installed on the phones. The T-shirt provided positive experiences, especially in terms of providing motivation (Uf1) and increasing performance (Uf2). While users did not have a negative experience with the T-shirt in terms of motivation and performance, there were negative experiences with the chest band. Users stated that their performance decreased (\"It did not increase my performance, on the contrary, I restricted myself in case it fell off\") due to wearability problems such as fit and mobility of the chest band. Comparing the visual aesthetics, there was no significant difference in the frequency values between the T-shirt and the chest band, but both products led to negative experiences in terms of size/form (V1) (frequency chest band = 10, frequency T-shirt = 12). The most important reason for this was that users did not want the technological parts of these products to be visible (\"If the device was a little smaller, it would look more stylish and hitech\"). It could be seen that the T-shirt had more positive experiences in visual experiences such as color, high quality appearance and good looking. The frequency value of positive experiences for good looking for the chest band was 12, and the frequency value of the T-shirt was 14. These results also showed that the users liked the products visually. Due to the fact that the chest band is worn under the clothes, users generally did not care about the visual aesthetics of the chest band. This situation also affected the social experiences.
