These are several project conducted during my bachelor and master degrees study:

Web-Based Laboratory Management System

The web-based laboratory management system was built by using CakePHP framework. The system was installed internally in 12 laboratories in Department of Electrical Engineering and Information Technology, Gadjah Mada University, Yogyakarta, INDONESIA. By using this system, the laboratory work, research, and  laboratory activities can be updated and shown interactively. Read the publication here.

Two Dimensional Eye Tracking

One of my master thesis research works was two-dimensional eye tracking system. Initially, the system utilized template matching algorithm to detect the pupil position. Due to noise caused by eye blink or fast eye movements, we modified the algorithm in order to increase the tracking accuracy. You can read my publications related to this research here and here.

Below, you can watch the 2D Eye Tracking implementation in Srinakarinviroj Hospital, Thailand:

Three-Dimensional Eye Tracking

The development of video processing technology has influenced the research on medical eye tracking. The 3D video oculography is required to measure horizontal, vertical, and torsional eye movements. By analyzing 3D eye movements, the medical expert can then diagnose abnormality occurred in vestibular or neurological systems. In the BIOSIS laboratory, we have developed a new prototype of 3D eye movements tracking system using dual-cameras acquisition. The system was mainly developed by using  Open Source Computer Vision Library, OpenGL, and Visual C++. The sampling rate is approximately 25Hz.
You can read our preliminary publication of this research here.

Here is the demo of our 3D Eye Movements tracking system:

Our system was used to record and analyze vertigo on a 56 years-old patient. The observation was held at Srinakarinviroj Hospital, Thailand:
