Listing problems that occurred during the city tour.
Type of error
Description
Number of occurrences
Lost Wi-Fi connection
Notification was not sent due to loss of Wi-Fi connection. For one participant this resulted in a missed turn. The human operator, however, managed to redirect the participant. In the case of the second participant, the city tour had to be ended prematurely. The only thing missing, however, was the showing of an image and information that the tour was over.
2
Low battery
Low battery notification resulted in that the participant needed to hurry up to finish the city tour.
1
Smartwatch touch functionality
The touch functionality of the smartwatch did not register that the participant had pressed or made a swipe gesture. However, none of the eight participants noticed the lack of touch functionality since the human operator noticed the problem and sent the notification as if the touch functionality had worked.
15
Human operator error
The human operator missed sending a notification. However, the two participants showed no signs of noticing that something was missing.
