User Testing 2
Our User Testing 2 (UT2) took place on 5 November from 12pm to 6pm.
Objectives
- Verify if users can react to AlterSense without prompting
- Test the intuitiveness of our user interface (photo taking) and hand gestures
- Gather user opinion about using AlterSense in a mall setting
- Test the accuracy of gender recognition in a mall setting
Location
- Level 4 of new extension between Plaza Singapura and Dhoby Ghaut
Unlike our previous user testing UT1, there would not be any demarcation marking the recommended standing position for shopper (about 4 metres away from the Kinect sensor) on the floor. AlterSense has been improved to use real world values; hence it does not matter where the shopper stands as long as the shopper’s whole figure is captured by Kinect.
Testers
- General public
- We had a total of 53 testers - 29 females and 24 males.
Execution Flow
1. Ask shopper if they have a smartphone and to download Microsoft Tag if they have one. If they are unwilling to download, we lend them our phones
2. Let user use AlterSense by himself/herself
3. Observe user if he/she has any difficulties responding to AlterSense
4. Measure the time taken for user to raise his/her right hand and to scan the Microsoft tag
5. Let user complete a survey form
Qualitative metric
Facilitators will be observing for errors or problems that the testers faced. Upon completion of all the tasks, the tester will be presented a survey form in which he/she will be asked about their opinion and satisfaction level of the application.
Quantitative metric
- Time taken for shopper to raise both hands
- Time taken to choose a hat
- Time taken to raise right hand
- No. of failed detections of raising of both hands
- No. of failed detections of choosing a hat
- No. of failed detections of raising his/her right hand
- Whether male shoppers had picked the top hat and female shoppers had pick the ladies’ hat
- Whether shopper has been able to complete the whole flow (i.e. shopper did not leave halfway)
- Response time to scan the Microsoft Tag
- No. of failed attempts to scan the Microsoft Tag
Observation Form: Main Findings
Time taken to choose a door is relatively longer than the rest because of the following reasons:
- Some people enjoyed interacting with the stickman and continued to stand there, hence increasing their time taken to choose a door
- Instruction to choose a door by walking to the left or right was not very clear for some people
- Some, especially the older generation, are not very familiar with following the instructions on the screen
- Some are not used to using hand gestures to make a choice
But the majority of the people eventually got the hang of it and became quicker in following instructions.

Tired but happy faces. Many thanks to Zhennan for helping us carry the heavy box back to SMU | Russell's not tired, still has the energy to look at the camera | Walking back to SMU |
