EyeTab

EyeTab is a 3D model-based gaze tracker that runs entirely on unmodified commodity tablet computers, taking their limited computational and sensor resources into account.

The code is available in two forms:

• A basic version which runs on a supplied example video file. This should give you an idea of the system's operation.
• An extended version for real-time operation on a Microsoft Surface Pro 2. Unfortunately camera APIs are non-trivial, so this is not guaranteed to work on other tablet devices.

System overview

Deployment instructions

EyeTab is written in Visual C++, a small extension of C++ which includes ... It should also work fine as generic C++ with minor replacements of VC++ code.

I chose not to include Visual Studio solution and project files as these will vary depending on how your dependency installations are laid out.

A very rough guide for setting this code up from scratch:

1. Make a new empty console application in Visual Studio.
2. Correctly include, link, and input the system dependencies.
3. Copy the source, header and resource files into your empty project.

Dependencies

The system has several dependencies:

• OpenCV - a multi-purpose computer vision library
• TBB - for multi-threading
• Eigen - provides simple vector maths

In addition, the SP2 version of the system depends on VideoInput for providing high-resolution access to the front-facing camera. OpenCV's camera API is broken and does not support this.
