Animal-Computer InteractionHCI is interested in pets too!
“Important recent research directly related to Animal-Computer Interaction has focussed upon companion animals and has mainly sought to develop interactive technology that aims to foster human-animal interaction while benefitting both sides of the relationship.”
Mancini, C et al. “Animal-Computer Interaction SIG” (2012). CHI ‘12 Proceedings of the SIGCHI Conference on Human Factors in Computing Systems.
“...[Owners] actively assume the role of animals, and infer thoughts and feelings from the animal’s perspective... [Projecting] human capabilities onto pets makes them legitimate participants in social interaction.”

PetSmart, Bloomington, INResearch: Toy ethnography
We went to a pet shop to see what cat toys already exist in the world.
We were able to explore and play with a lot of different toys to test their movement, weight, etc.

A large number of cat toys are amusing for humans just as much as cats (obviously cats don’t smoke cigars!).

Arduino CirCAT BoardOur purrototype
Cats love to attack birds, feathers, and any moving objects!
This prototype combines two toys (ball track and stuffed bird) into one playful, colorful toy.
![Page 20: Arduino CirCAT Board](https://reader034.fdocuments.in/reader034/viewer/2022052623/559e9aff1a28ab02208b4825/html5/thumbnails/20.jpg)

Tail feather waggingHow it works
The ball in the track triggers a light sensor When the ball’s shadow passes over the light sensor, the servo motor (hidden in the box) wags the bird’s tail feathers
![Page 21: Arduino CirCAT Board](https://reader034.fdocuments.in/reader034/viewer/2022052623/559e9aff1a28ab02208b4825/html5/thumbnails/21.jpg)
21
Bird chirpingHow it works
The ball in the track triggers the flex sensor when it bounces against it
The piezo speaker hidden under the cardboard wire cover makes “chirping” sounds when the flex sensor triggers

Humans can play too!User testing
Humans can also get in on the fun, bringing them closer to their pets and increasing enjoyment for everyone.

Making of the Arduino CirCAT BoardConstruction process
Following is a series of photos showing our general process in working with Arduino and our toys.
![Page 28: Arduino CirCAT Board](https://reader034.fdocuments.in/reader034/viewer/2022052623/559e9aff1a28ab02208b4825/html5/thumbnails/28.jpg)

Examining the toys to see just how we can hack them
Trying the original toys
For our proof-of-concept prototype, we chose to use only a portion of the available track, just to make sure the sensors were easily triggered.
![Page 29: Arduino CirCAT Board](https://reader034.fdocuments.in/reader034/viewer/2022052623/559e9aff1a28ab02208b4825/html5/thumbnails/29.jpg)

Making the electronic components work
Wiring the Arduino
We used online tutorials and the help of our fellow classmates to determine how to wire all of the components.
![Page 30: Arduino CirCAT Board](https://reader034.fdocuments.in/reader034/viewer/2022052623/559e9aff1a28ab02208b4825/html5/thumbnails/30.jpg)

Making sure it’s doing what we want it to do
Testing and more testing
Before building the actual prototype, we had to test each component many times to make sure the output was what we expected.
![Page 31: Arduino CirCAT Board](https://reader034.fdocuments.in/reader034/viewer/2022052623/559e9aff1a28ab02208b4825/html5/thumbnails/31.jpg)
31
Hooking the sensors up to the toy
Putting the hacked toy together
We used hot glue to affix the toy together with our various sensors and other electronic components.
![Page 32: Arduino CirCAT Board](https://reader034.fdocuments.in/reader034/viewer/2022052623/559e9aff1a28ab02208b4825/html5/thumbnails/32.jpg)
32
Making sure the cats can’t chew through the wires
Covering the wires
For safety of both our cat users and our toy, we covered the wires and Arduino board using an inexpensive cardboard box that we decorated with paw-print paper.
![Page 33: Arduino CirCAT Board](https://reader034.fdocuments.in/reader034/viewer/2022052623/559e9aff1a28ab02208b4825/html5/thumbnails/33.jpg)
33
Thinking about materials and our processReflection
Originally we planned to add a feather that shakes, and LEDs to attract the cats’ attention depending on where the ball hit. We quickly decided not to use LEDs as it did not add much to the experience, and it would have gone mostlyunnoticed by the cats.
We added a piezo speaker instead to buzz when the ball pressed on it. While tuning the piezo, we started calling the beeping “the bird chirp”, and we tuned it to a noise that resembles a bird. As we were setting the pieces in their final spots, we realized we could integrate a toy bird easily.

Things we’ll remember in the futureLessons learned
Prototyping is about playingWe eagerly iterated to improve our prototype aesthetically as well as functionally. We believe this was because we were having a lot of fun. Playing with Arduino as we started was essential to getting us excited about the technology, and triggered ideas for possible applications.
Don’t rebuild the wheel (or code)Rapid prototyping embraces the idea of proof-of-concept. It is OK to reuse code and re-purpose existing solutions to fit our concept. As long as it illustrates the interaction and it works, it’s fair game.
Tutorials, Youtube, and other people are keyLeverage existing knowledge for troubleshooting and to gain insights as to why something might not work.

35
Things we want to try out next!Ideas for the future
We’d love to play around some more and try out the following with Arduino:
• Something wearable (cat collar Arduino?)
• A cat tracker (to easily find where they’re hiding)
• Embedding sensors in the house (ambient detection)
• Something that we could use on a regular basis (hacking or augmenting daily use items)
