The task

To convert a song on the audio cassette into mp3 and send it via bluetooth to your phone using the cassette player.

What worked

• The main thing was that the player incited user interaction without even prompting users. (Noticed a couple of users interacting with the player while I was testing out other models)
• The cassette control buttons and and cassette slot interaction was understood by all the users.
• Got feedback that the player does look to scale and has good finishing.

What didn’t work

• Volume knob did not have any label hence it was a bit confusing. Users figured that it is the volume knob but would have like to see a label.
• The notch for pulling out the cassette player slider was a bit smaller for some users.
• The sliding movement was not very smooth.
• Assumed users will interact with screen first, but most of them inserted the cassette first and then interacted with touch screen. Some screens I had created for cassette instructions were not of use.
• Some used the cassette insertion as the normal pull out at an angle and slide the cassette in; instead of sliding out the entire cassette tray.

What would I change

• Support multiple entry points to the task, screen as well as cassette. Will add screens accordingly.
• I would change the connect device button on home-screen to play via bluetooth. To have uniform level (play something) at home-screen.
• I would make the sliding interaction smoother that what it is.
