I'm back, and so is Sotto

A project log for Sotto: A Silent One-Handed Modular Keyset

The essential input you never knew you needed. Sotto is a portable, wearable, more subtle way for you to text and type on the go.

First log in a while, between some busy-ness at the day job and a crazy move from San Francisco to Los Angeles. Moving two cats for 6 hours in a car is no joke.

In the meantime, I've been thinking a lot more about Sotto and how to integrate it more naturally into the hand. These thoughts are based on where to place sensors, and what feels the most natural when it comes to typing-like actions.

Chorded keysets should work similarly to playing the piano-- but when playing the piano, pressing keys, and more, there is a certain amount of resistance and haptic feedback that occurs. I'm more comfortable (and certain of what I'm typing) when I tap the "right letters" lightly against my leg or a desk, barely moving my fingers, than I am when I type by wiggling my fingers indiscriminately in the air. It's difficult to isolate a single finger movement in the absence of resistance and feedback.

With this in mind, I'm reimagining/evolving Sotto to account for movements that feel a bit more like button pushing. Starting with some crazy attempts at makeshift FSRs, from my half-unpacked boxes.

Here's two pieces of conductive fabric, not touching each other, with a piece of anti-static bag separating them. Plus, some adorable tape I was using to label my moving boxes :) I also threw in a pulldown resistor (not pictured).

I'm getting a lot of junk over serial, but when I'm pressing the improvised FSR, the average reading is definitely higher. I'm thinking about what these would look like stitched into the end of a glove, or at the very least, taped to the ends of my fingers. I'm gonna go unpack more boxes and think about it. Stay tuned.
