migB Can you feel it ?

The question is rather if it is able to feel you. One of the main ideas to give more interaction to migB is to make it tactile. I agree it seems a bit ambitious. At first we thought about adding a few buttons around the surface but it would remove all the fun. Hence, the idea of tactile came naturally. It allows many gameplay possibilities. Tap the ball like if there were a button. Place your fingers according to a pattern to solve an enigma. Hide a part with the palm of your hand…

The precision is not the biggest issue. Many physical quantities may be used to detect the contact of a hand with migB : heat, pressure, light…

So many possibilities to explore, sensors to find and connect efficiently to our PCB. Let’s go.

    “So many possibilities to explore” : before next friday 🙂

  • A few friends and I tinkered a “ball” (egg shaped) that controls music depending on its orientation and how you squeeze it.

    The 1st prototype won a hackathon, then we made a more serious version. It’s made with hermetic silicon so it can detect hand pressure using a barometric sensor. Before we chose this solution, we had a few ideas about how to make it tactile, here are some of them:

    1) The cheapest: a simple wire can be used as a capacitive sensor but it’s not the most reliable if you put it close to any metal.

    2) The most experimental but quite intriguing: 3 IR LED and 1 IR sensor. By changing the internal shape, the way light propagates inside can be used to detect where you press.

    This paper (pdf)
    can be a good source of inspiration.

    3) The reasonable trade-off, barometric sensor.

    I took a few quick notes here but it’s old and needs cleaning.
    Let me know if I can help anyhow 😉

    PS: On a less serious note, your ball would be quite interesting if it could fly or crawl ;p

    Wow ! It seems really fun. Thank you Drix for your help. Just for curiosity, how much time did you have for this project ? It looks accomplished.

  • The Hackathon took 48h, we used http://twiz.io, the other version took a couple of months but it was a side project…
