- My main users are cats; they seem very intrigued by the shape and the way the 3D-printed cat feeder works. They were able to figure out that they should go to it when the food gets released. I am not sure whether they fully understand the mapping between the controls and what happens in the experience, but they seemed very invested in the process of me wiring and testing everything before gluing it together.
The servo works well. I discovered that my LCD display pins might have been misaligned by one pin, which caused the vital parts—GND and power—to be connected incorrectly, and it took me a while to figure out what was wrong. However, I switched to an LCD display I had from an older kit.
For the human users, it is quite clear: they have a remote with an “OK” button on it. It was obvious that this is what they needed to click to dispense the cat food. The cats also seemed to understand that it dispenses food, but they are not that excited about it.
I decided to interview my cats to see their understanding between their controls and their experience, and their overall experience.
Cat 1: Bella: Refused to interview with me
The demo with people user: My sister was able to figure out it used when she saw the remote by clicking the “OK” button to release the food from the cat feeder.
Cat 3: Oreo: Provided a demo
