Testing a Microwave! Maya Klitsner, Jingle Huang, Melissa Pao
Our Choices Our tasks: 1. Popcorn making 2. Removing and inserting microwave tray 3. Setting timer and power level of the microwave
Our Choices We measured: 1. Frustration level 2. How long it took 3. Steps taken
Our Choices Our subjects: ● 18-22 year olds ● One male, two females
Frustration Levels Here is Catherine’s frustration levels for each of the tasks. Catherine never found a task particularly hard. This could have been due to the fact she said she uses a microwave 3-4 times a week.
Mary’s Frustration Level Mary’s frustration levels were higher for popcorn but lower for the turning plate than the other users. For popcorn she was the only one to not use the popcorn button.
Tom’s Frustration Level Tom’s frustration level stayed exactly the same for every test. He said that he was “way more anxious than frustrated” when it came to testing out products.
Time Tasks Took The graph to the left shows how long each task took each person. By not using the popcorn button, the time to cook popcorn was almost as long as the it would take to make popcorn.

Used popcorn button
Set time with knob. Had trouble starting the microwave
Used popcorn button
Spun plate until it fit into the grooves

Spun plate until it fit into the grooves
Spun knob to find right time Pressed start Set the power
Spun knob Tried to set power Got error Tried different combinations till power and time was set properly
Spun knob Pressed set power Got error Set power Pressed start
The strategies between each task varied between each person based on their past experiences with microwaves.
General Observations
What might we do differently if we rerun the test 1. 2.
Allowing only one participant in the room once Rearranging the sequence of tasks We should make “tray in and out” task the first, so users won’t be burned
3.
Reduce overlap among tasks So knowledge learned in one test won’t help users that much in the rest
