VeyeZER Graph

VeyeZER™ Graph

VeyeZER™ Graph is an assessment tool which uses the study of eye movements to provide valuable insight to the underlying factors causing reading impairments. The VeyeZER™ Graph application consists of software which runs on the HoloLens 2 headset and personal computer.


The HoloLens 2 used by VeyeZER™ Graph tracks saccades or eye movements.

Saccadic eye movements are rapid movements of the eyes which abruptly change the point of fixation. These movements are natural when reading a passage of text. However, saccadic movements which indicate distraction (movements up and down), long periods of fixation on certain words, skipping words altogether – can point out why readers have trouble with comprehension. VeyeZER™ Graph uses data collected from saccadic eye movements to evaluate reading performance based on standardized norms for grade levels.

Using eye tracking tools to better understand factors affecting reading comprehension has been in practice for over 30 years.

The tool Visagraph, created by Stanley Taylor, entered the market in 1985. Visagraph is no longer being manufactured. VeyeZER™ Graph was built on the concepts of Visagraph testing, but the VeyeZER™ Graph software runs on the Microsoft HoloLens 2, state of the art technology which is widely available in the marketplace.

Benefits of VeyeZER™ Graph

For Kids

Tackling reading problems is a tough job for anyone, especially kids. VeyeZER™ Graph uses the concept of gamification to combine the functional ability of tracking and assessing eye movements, while kids enjoy using the gaming aspect of an Augmented or Virtual Reality headset. Kids actually WANT to try VeyeZER™ Graph and see what it's all about!

For Optometrists/Teachers

Eye Tracking tools play an essential role in evaluating factors affecting reading comprehension. VeyeZER™ Graph provides informative graphical data charting a subject’s reading skills in comparison to standardized grade level averages. The hardware used is brand recognized technology noted for its appeal and durability. The application is user friendly for both the subject and the clinician.

For Parents

Using VeyeZER™ Graph, parents can view video replays of their children’s eye movements as they read a passage. Experience the assessment results by seeing how each word was read. No more guessing about where the problem lies, the data is readily available in formats which are easy for everyone to understand.

"We are excited about the VeyeZER Hololens System, which represents a seamless interface between Augmented Reality and clinical ophthalmic diagnosis. It presents a compelling visual stimulus and audio feedback that patients respond to easily, and the 3D eye movement tracking technology provides robust and reliable data. More than just a competent replacement for older eye movement tracking systems; VeyeZER is a solid, next-generation platform with tremendous potential for a vast number of future clinical and research applications in the eye care industry."

How Does It Work?


Clinician uses VeyeZER™ Graph application to log subject related information and set appropriate reading passage.


Subject wears AR/VR headset and begins application with voice commands.


VeyeZER™ application records data and sends it to the cloud.


Clinician is able to retrieve data and display it for evaluation.
