Some basic facts to get started:

Human based design:

Going smaller:

The Prototype:

Empathy in Braille.

Tactile Display.

This project focused on creating a completely new way for blind people to experience the world around them. This tool would be able to take in any input signal and create a totally custom vibrating pattern.

 

This required a "back to basic science" approach, designing something around the human anatomy, and researching how a brain recognizes haptic nerve signals. The final prototype was designed using micro structures to withstand macro forces.

 

This project was funded by and presented to:

The brain has over 25,000 nerves per sq cm meaning you can feel nanoscale ridges.

 

The brain can't handle all of those signals so it reduces the tactile resolution to 1 sq mm.

 

The brain naturally senses rhythm and patterns better than a static signal.

The display is a large matrix of small, square millimeter vibrating pixels. They are designed to vibrate only about 10 microns, so they can be small and naturally vibrate in the region a brain can detect comfortably. Each pixel is a micro scissor lift which is driven by a simple electric signal.

 

The following is how math transforms into shape.

The pixels had to be made to vibrate indefinitely, and to never break even under compression from someone pressing down on them. The final design was made using photolithography and driven by laser cut piezo electric actuators, after comparing designs made from casting, 3D printing, and MEMS techniques.

 

Here are some images of the pixel design going from predictive analysis to fully working mechanism.

The pixels are 5 mm long, by 5mm high.

The final 4 x 4 prototype was created to prove the design, and to show that it could create a variety of patterns. The final design incorporated machined, 3D printed, laser cut, and MEMS parts. The design ensured that an electric signal could travel from some source and translate into an isolated vibration.

 

It was then paired with a computer vision program co-developed in MIT that can recognize emotion.

 

The final stages of the project were then to pair different outputs to easily recognizable patterns that different people can feel and discern.
