HTA - Hierarchical Task Analysis
1. Tracking: View the current location of the dog and the places where has the dog been to in a week; turn on the lost dog mode
2. Socializing: Post one photo of the dog, add words describing feelings, comment on others’ posts
3. Ranking: Find out the rank of the dog today and a friend’s dog ranking today
4. Menu: give authority(owner or walker) to other users, find edit profile icon, connect to instagram
5. Health: find the activity and sleep data, locate strain score icon (time for rest)
The participants were asked to perform the following tasks -
Task 1: Tracking
1.1 Track the current location of the dog
1.2 View walk routes history
1.3 Turn on lost dog mode
1.4 Walk streak
Task 2: Socializing
2.1 Post photo of your dog
2.2 Like/comment on other people's posts

4.1 Give authority(owner or walker) to others
4.2 Find edit profile icon
4.3 Connect to instagram
Task 5: Health
5.1 Find the activity
5.2 Find the sleep data
5.3 Locate strain score icon

Since 'Tracking' and 'Health' are the features with utmost importance and are the key features, further study has been done only on these features.
Looking into 3 tasks mentioned above -
This section has newly proposed HTAs, conceptual design ideas to make the existing designs better and new interface designs.
Task 1: Current location, walk route history

The new interactive prototypes were developed with the help of Figma and were tested with users.
Design System:
Usability Testing
Testing Method - Think aloud testing
No.of Participants - 9
Study design - Mixed subjects
The old version was tested with first and new version was tested next for half of the group and vice-versa for the next half of the group.
Main tasks:
1.Tracking for location
2.‘Find’ my dog
3.Find and view Activity data
Tools used:
Useberry - Advanced user testing tool
Zoom - recording / transcription
Think aloud testing:
Location tracking:
1.Could you locate where the dog is at currently?
2.Could you view the dog's walk route history?
3.Could you view the dog's walk route history for the 15th of Feb?
‘Find’ my dog
4. Imagine your dog escapes, how would you find it using 'Fi' app?
5. Continuing the previous scenario, how would you turn on collar light if your
dog is in the dark
6. Could you change the light color?
Activity
7. Could you show me how would you monitor the activity of the dog?
8. Could you show me the activity data of the dog for the 8th of March
9. Could you show me the activity data of the dog for the 8th of March on 11 am?
System Usability Scale (SUS) - Questionnaires
Participant Demographics:
Results:
Time of completion was not recorded as "Think aloud testing" was being conducted and it would increase the time taken to complete a task.
Ease of use - tradeoffs
Comparison of user flows:
System Usability Scale - Results
Comments from the users - New system:
"So user-friendly!"
"Easy to change collar light and select dates for longer period."
"The “health” icon is confusing, won’t expect to find activity and sleep data under 'health'"
"Extra unnecessary efforts to click outside the calendar to change to the right date"
"Calendar icon too small to click on"
