Simulate Swipe Gesture for Mobile Apps

Projects General Guidance
1

Hi,

I am looking to build an arduino device that is small enough to be put on the finger that connects via bluetooth to the phone and when swiped left or right can swipe left or right in an app I build using react native or native android.

Is this possible?

Anyone able to help me with direction on whether or not the hardware below is good enough and if I need along with it any other pieces and any code guidance?

I am looking at this hardware-wise

Not sure how to power this, can someone suggest a battery that can be connected to this?

Appreciate it, anything helps.

So you basically want something that can detect the movement of a finger through the air?

Step 1: come up with an idea on how you could possible detect this movement (don't bother about size/MCU/etc, just figure out the principle).

Step 2: find a way to implement what you imagined in step 1.

It's tough, really tough.
