Inspiration

I read a lot on my phone. One of the aps I use periodically has promotions in which they'll give you coins that can unlock chapter in exchange for reading certain stories. Trick was, I had already read all of the stories they wanted me to read. So, I did what anyone would do, and tried to swipe through the stories again as quickly as possible. As always, I look for ways to make time-consuming and repetitive things more efficient. That is the inspiration for this project. It can also have application for people with multiple disabilities (like low-mobility and low-speech ability, who aren't able to use voice commands effectively) or people who don't want to figure out the settings that'll make your phone scroll on its own.

What it does

It scrolls through your phone, like you would do with your finger. A servo moves the "finger" back and forth like a pendulum, and a motor turns a gear that is part of a linear movement mechanism that moves the pen up and down (so when the pen goes backwards, it isn't scrolling back to where it started)

How we built it

This simple phone add-on could be made from 3D printed material, 2 motors/ servos, one of those touch-screen pens, and a small microcontroller (like an ESP8266 -01)

Challenges we ran into

I did not take into account the time it takes to 3D print things.

Accomplishments that we're proud of

CADing the initial design.

What we learned

I spent time making the materials I have work, but I won't be able to have a working prototype because I ran out of time. If I had focused on the design and research side of this project, I would have a more put-together final product to present.

What's next for No-Hands Scrolling

The next step would be to finish fabrication and iterate.
