At a lose for words? Can't describe an object? PiZero SmartGlass can help you with that by using image recognition tech. Make your own smart glasses easily with the Raspberry Pi Zero! Affordable and easy to build, retro-wearable 3D Virtual Stereo Digital Video glasses are around $75 along with the Pi Zero. This display uses composite video to connect the Pi Zero's video out pins and are easily customized. There are many applications for image recognition, which allows computers to translate written text into digital text. The PiGlasses can help with the field of machine vision, recognizing people and objects. Add a battery pack and your PiGlasses are ready to go!Project pages:
The OLED display is a small .96" display controlled by an arduino nano board. The display receives text and commands from a HC-05 serial Bluetooth module connected to the arduino. There is also a small speaker and RGB LED connected to the board. The OLED display, RGB LED, and speaker are all controllable over Bluetooth.
The device is powered by an Adafruit powerboost module connected to a small 0.7Wh lipo battery. The optics are a small mirrored right angle prism and a magnifying lense. The frame and casing is all 3D printed with ABS using a Solidoodle 2 pro printer.
The Arduino communicates with the OLED display using i2c (inter-integrated circuit). The RGB LED and the speaker use the arduino's digital output pins. The display is controlled over blue tooth using a application running on an Android phone or Linux terminal. The glasses are very portable and foldable.
Total cost ~$60.
Clay’s DIY “Google Glass” uses the sensors on the Arduino Esplora along with the Arduino LCD screen and a 3D printed frame.
He can use voice commands to bring up a calendar with his schedule, local maps, and temperature and weather info.
A headband on the back keeps it from tilting to one side.
“Now they are extremely comfortable,” says Clay. “In fact I wear them around my house and tell my parents the temperature just for fun!”
In this video we demonstrate a custom eye tracker for Glass that can be built for $25 and using a Makey Makey with Glass.
Glass supports touch gestures (e.g., swipe, tap, scroll), head gestures (e.g, tilt up turns display on, gesture down turns display off), and voice controls (e.g., "ok glass", voice input). By using the IMU sensors directly (as we show here) it's simple to extend the range of head gestures. There is a proximity sensor that is used by Glass to determine if the device is being worn. It is capable of recognizing wink/blink gestures but it cannot actually track the gaze of the user.
We hope that these new input methods can be used to expand when Glass is relevant for use (e.g., with your hands full) or who can use it (e.g., users with disabilities). They are intended for developers and researchers, we don't intend for people to use our eye tracker while walking around. It's essentially a very cheap and easy way for all of us to have this feature before it is integrated into the device directly (eventually some manufacturer will do it) and if we find interesting use cases it may even advance the timeline for their inclusion. All of the code and 3D models are available in http://www.WearScript.com.
