Conducting Usability Testing with High Fidelity Prototype
We conducted our usability testing with 6 participants who live in the school dorm. The testing and interview were conducted outside a dorm room next to the lobby.
Main Stdy Focus:
How do students communicate with the kiosk (Verbal cues)?
Do they prefer voice or speech-based user interfaces?
Is the screen visible to different users when seated or when standing?
Mobility across the dorm corridors.
Kiosk Physical Design Insights
Most users found the height to be optimal.
In narrow student dorm corridors, it was not taking up much place, thereby not causing any major obstructions to residents walking in them.
The motion was smooth on the various terrains of the dorm, from carpeted floors to marble.
Voice Interface
Users found it easy to talk to. The Voiceflow system was able to correctly identify most sentences.
A few users said it would be ‘weird’ to talk to such a mechanical kiosk in the dorm corridors.
During testing, the voice flow system would end if one scenario was done with. We had not accounted for the fact that users would face issues if they had multiple queries.
We observed that the Voiceflow system had difficulty detecting short one-word responses (Yes, No, OK).
Screen Interface
Users found the screen interface helpful in viewing the information presented by the kiosk; however, most preferred speaking to it.
Users preferred a clean interface, large font, and images.
Some tried tapping on the screen even though the screen was display only.
Miscellaneous
At the end of the interviews, the users suggested other functions that they would find useful.
A notification feature that their food delivery/amazon package was ready to be picked up from the lobby.
A feature to adjust the air conditioning in the corridors.
Information on the menu of the dining hall that day.
