Feasibility study on the use of eye-tracking technology for amblyopia prevention in infants

In the preliminary investigation of the Genesis VisionTest research project, various eye-tracking models were examined to determine their suitability for use in the project. The criteria were stability, parallelism, and compatibility.


Several models were compared as part of the work. Only models freely available on the market were considered in the investigations. As none of the models were able to fully meet the requirements, a common interface for connection to the planned software was created in the second step.


The investigation showed that it is currently not yet technically possible to capture the gaze positions of several people simultaneously. Furthermore, investigations have shown that the size of the viewbox plays an important role. The manufacturers' SDKs do not yet allow any intervention in the recording, meaning that no selection of persons is possible without further adjustments.

Tactile maps for blind people made by 3D printing

Tactile materials are suitable means of making it easier for blind people to understand spatial circumstances. In the past, however, these were produced exclusively by hand and were therefore expensive and often only sparsely available. Recently, however, 3D printing has become increasingly important for the creation of tactile materials for blind people, as it can eliminate some of the disadvantages.

Unlike professional 3D printers, consumer 3D printers have only been available for a few years. However, these are already affordable for end users and allow them to print a variety of 3D models available on the internet. It is conceivable that blind people could benefit from this technology in the future. This educational research project investigated the possible influence of printing phenomena of current commercially available 3D printers on the readability of tactile maps.
