1. 2nd Iteration of My Prototype

• Goal of the project and/or desired interaction
  I hope to be able to press on a force pressure sensor to activate the camera for the face detection to track my motion and then turn the camera off by pressing on another force pressure.
• Quick description of assembly and list of core components
  – Arduino x1
  – Small Bread board x1
  – Force pressure sensors x2
  – Servo motor x2
  – Jumper wires
  – Resistors 220ohm x2
• How it works
  When you stand in front of the camera, it will not work but when you press on 1st pressure sensor, the camera will start tracking your motion and turn towards wherever you are moving. You can turn the camera off by pressing on the 2nd pressure button.
• Any problems you encountered and/or solved
  I have encountered many problems with the code where the code tends to be stuck in an IF statement and another problem I still face is that the code only runs once. After running once, it won’t activate again unless I restart the Arduino and processing sketch again. I still haven’t figured out what is the problem since the code looks all correct.

2.  Your playtesting plan and desired feedback

Who will you playtest with?
I will playtest with my fellow peers from Design & Technology program and possibly some other same age peers from different programs in Parsons.

How will you get their consent?
I will ask them if they are willing to test out a quick interaction and give me some feedback.

What feedback do you want?
I want the interaction of my model doll dog to be intuitive so I know where to exactly design my pressure sensor on my model dog.

What questions will you ask?
What is the first intuitive response of placing your hand at (on my model doll dog)?
Where do you think you can press to activate music?

What information do they need to know before starting?
I will give them a basic overview of my concept.

How much will you help them during the test?
Aside from trying to give them a basic overview, I will try to let them figure out themselves. If they really need help, I will give them hints.

How will you debrief them?
I will let them know what I’m really testing orally and ask them if they have any questions.
