This is a project to achieve very low cost Augmented Reality glasses.
Some unique characteristics for this project are:
- Custom positional tracking using reflective markers
- that allows for long tracking range above what is possible using QR codes
- that is extremely lightweight, and runs on low performance processors such as MediaTek
- works exceptionally well in low light conditions
- allows for low battery drain
- reflective QR codes allow for data to be attached to a marker. When a reflective blob is detected, a high resolution photo is taken so that the QR data and orientation can be read from a large distance.
- Using cheap, off the shelf hardware; namely Chinese imported MIX phones.
- which cost currently $70 and are readily available
- with a range of alternatives available
- in the future, other phones can be supported. MIX phones are used solely for their long flex cables leading to the front camera.
- alterations to the phone are simple and low cost
- the frame for the AR glasses are Chinese imported for a cost of $30~. The FOV is about the same as the camera, 60-70 degrees.
- Tracking is implemented using an Android service. There is no need to build the tracker with AR apps. There is seamless transition between apps because of this as well. The Android tracker service will also have the ability to put the device in auto standby on no input, or wake the device up on movement or marker detection.
- There is no need to root the Android device. The requirements for Android level are low and should work with any Android phones available.
- Unity3D support is available and working smoothly.
- Maintains 60fps
