Listen To Your Feet, They Have A Lot To Tell You

[Umar Qattan] is in tune with his sole and is trying hard to listen to what it has to say.

At a low level, [Umar] is building an insole with an array of force sensors in it. These sensors are affixed to a flexible PCB which is placed in a user’s shoe. A circuit containing a ESP32, IMU, and haptic feedback unit measure the sensors and send data back to a phone or a laptop.

What’s most interesting are the possibilities opened by the data he hopes to collect. The first application he proposes is AR/VR input. The feedback from the user’s feet plus the haptics could provide all sorts of interesting interaction. Another application is dynamically measuring a user’s gait throughout the day and exercise. People could save themselves a lot of knee pain with something like this.

[Umar] also proposes that an insert like this could record a user’s weight throughout the day. Using the data on the weight fluctuation, it should be possible to calculate someone’s metabolism and hydration from this data.

    He has only one sole? That’s unfortunate, but good to know being minus a foot isn’t stopping him.

  2. Computer-in-a-shoe reminds me of the Eudaemon shoe computer (worth a google). These days they could make a smaller, faster, better communicating version of it using a similar design to what is in the article, or an even more powerful microcontroller.
