User testing Video
Have people try your project without giving them any
prompts/instructions and see how they use it
Sidenote: I advice to lower the volume of the video since there were people being loud nearby
• Are they able to figure it out? Where do they get confused and
why?
At first, I forgot to mention in the instructions page what the potentiometer was, which is why the person who tried my game couldn’t figure out what was the tool that controlled the size of the sphere. After this, although it didn’t take her long to understand how the potentiometer worked, she commented that it would be helpful to have a small description of how it is used.
Do they understand the mapping between the controls and
what happens in the experience?
Fortunately, they did understand what the potentiometer was doing to the sphere and expressed her interest in the interaction.
• What parts of the experience are working well? What areas could be improved?
Although so far everything in my sketch and Arduino works as I wanted
- The sphere shrinks and grows in response to the potentiometer
- the songs change in response to the button
- the red LED turns on when the sphere reaches the maximum or minimum size
- the green LED turns on when the sphere reaches a small range (between 290 and 300)
- the “winning” size triggers the end page and then the user can go back to the homepage
- there is a homepage and an introduction page
I feel like I could add a last component to make it more interactive, which would be the spinning of the sphere with another potentiometer. I think I could also make the growth and shrinking of the sphere far more smoother, and maybe add some exciting element for the winning page. While I am aware that on the surface this interactive project seems simple, it has forced me to push myself far outside my comfort zone, and I am happy with my progress so far.
• What parts of your project did you feel the need to explain?
Like I previously mentioned, I realized I failed to explain in the instructions how the potentiometer works and how it can be identified by those who don’t know what it is. I also realized I need to explain what happens when the spheres reaches the incorrect sizes that trigger the red LEDs and what triggers the “win”.
- How could you make these areas more clear to someone that isexperiencing your project for the first time?
I believe it would be best to introduce this information in the instructions page since this is the most efficient way to inform the user while also keeping their focus on the information before splitting their attention to the p5 sketch/screen and the Arcade/arduino game box.
