This is very interesting and I commend you for your efforts.
Less expensive devices display fewer characters per line, and require the user to read the standard 80 characters of a normal text line in several readings.
The modified cam is a nice trick but it does not fully exploit the electromechanical properties of the tiny motor.
The only criteria is that you would still need to do a prior patent search.
We can appreciate the importance of keeping up with the changing times through technology.
On some models the position of the is represented by vibrating the dots, and some models have a switch associated with each cell to move the cursor to that cell directly.
Thus the movement of the cam, wold cause the cam follower to move up, that flexes the lever pushing the braille pin upwards and the lever is displaced from its natural position.
I actually met Paul at a local Maker Faire and we instantly connected because of our shared efforts on braille and I was amazed and intrigued by his genius ideas for actuation.
Looking at the pin arrangement and the suggestion of using coils and magnetized pins made me think of another technology: core memory.
