Exploring Senseg/ Prior circuits

The Senseg Feelscreen Developer Kit is helpful in visualizing the goal of my project. It also shows the Electrovibration phenomenon. The Senseg is limiting because it is one pixel and uses visual guidance and position of the finger to trick the user into thinking there is haptic feedback in only one part of the screen. In reality when you touch part of the screen, turning on the haptic feedback, the electrovibration sensation can be felt on the whole screen not just the specific area.

After exploring the Senseg it's clear that I have to create a new screen and circuit that enables multiple pixels. With multiple pixels the electrovibration sensation will be felt on specific areas of the screen only, allowing someone who can't see to feel specific effects without relying on vision to differentiate the part of the screen with the perceived haptic feedback.

Looking at the circuit and screen already built I have to spend some time exploring them and my next step would be building off of what is made.

The screen already built appears to be made of copper board and an insulating film. Goal is for copper board to be a grid and connecting certain number of points (multiple pixels) can feel a shape.
