I'm going to try and update this more on various projects that I am working on. And there are a few.
They all center around the new suit I am working on and the various technologies that I am involved in to make it happen.
I will use technical terms here so feel free to Google them.
Goal:
1. To make a suit that can 'read' the users emotions and facial movements and duplicate them on the suit.
2. A way for the wearer to control various aspects of the suit without being seen to control the suit..
I'll cover point 2 first. With the intra-oral interface

The main issue here is with the magnet. However I have discarded the magnet system for a touch membrane system.
http://www.instructables.com/id/Sti.....ytape-Sensors/
These are incredibly sensitive and perfect for using with tongue pressure. I will combine them with an Arduino and A/D to read touch and pressure levels. Currently awaiting shipment of copper foil with conductive adhesive, plus 8 channel I2C A/D SMD Chips.
1. Main suit.
a) Facial Waldo. This is a mask that goes over my own face. It will contain various sensors to either map the muscles movements or the reflectivity of the eyes. The eyes being to trigger the suit eyelids for blinks or squints.
The rest will be to pick up the facial movements. This is an example (Not Mine) of a waldo

However mine will be a lot smaller.
Currently worked out.. Using mini potentiometers stripped from small servos (because they are both tiny and require minimal pressure to move) I have the eyebrows worked out. Edge of the mouth will be handled with stretch sensors

Which work well with more motile connect points.
I have moved away from the camera and voice system for lip movements.
The Camera system did work however I needed a distance between the camera and lips to get a good image. Also processing power for using the SimpleCV libraries at more then one FPS was beyond RPi or BeagleBoneBlack. I did have more success with the ODRIOD XU but the camera positioning was the main issue.
Using speech to capture Phonemes was beyond internal processing power and would require a link back to a computer somewhere.
Main head - slow progress and concentrating on the emotional pickups which will drive what can be displayed. However have dropped Silicone skin due to weight and have gone back to using Latex Foam which is lighter.
Eyes have now been completed as units and back color can be changes using AdaFruit Neopixel rings http://www.adafruit.com/products/1463 where all colors and intensities can be displayed as well as patterns and revolving rainbows.
Yes - progress is still going on.. :)
