What does the patient need to do during testing?
The patient sits in front of the display and uses a computer mouse to control a tracing disc on the screen. The task is to align the disc with the real-world target—an intuitive procedure performed under both monocular and binocular conditions.
Can the platform be used with children?
Yes. The task is designed to be quick and easy for both adults and children. The system has been successfully tested with children over 6 years independently, and with children aged 4–5 years with parental assistance.
How is the target positioned in front of the display?
The innovative ToDS (Target on Display System) holds a physical yellow transparent disc at a fixed distance from the display center. The software provides precise guidance on where to place the target base, ensuring accurate 3D positioning.
Is the platform compatible with any display / web browser?
Yes. The ToDS works with most flat and curved displays of any size. The only limitation is for displays with very thick borders (>2.5 cm). The web app has been tested with all major browsers, including Safari, Chrome, Firefox, and Edge.
How is measurement quality ensured?
The platform includes a calibration procedure that aligns the patient’s midline with the screen center and keeps the face parallel to the display—without using a camera. At the end of each session, the software generates a quality score. If the score is below the recommended threshold, the operator is prompted to run additional repetitions for optimal accuracy.
