Help us improve screen zoom technology for the visually impaired! We are conducting an experiment and your participation can provide us with valuable data that will be sent to the developers of new products that make life with screen loops easier. The experiment will require only 15-30 minutes of your time and does not involve any significant effort. You can conduct an experiment on your car at your leisure. All you have to do is download the software according to the instructions below and email the results to the main researcher Jeffrey A. Wilson .
You can download the experiment materials at the following address:

This experiment will take from 15 to 30 minutes. We ask you to find a green target on the screen that may not be visible. If it is not visible on the screen, the visualization will point you in its direction. You can do this experiment on your own machine by downloading the above program. The only requirement is that you have a personal computer running Windows with a screen resolution of at least 1366 by 768 pixels.

After completing the experiment, please send your results to Principal Investigator Jeffrey A. Wilson . We appreciate your interest in our experiment and hope that you will be a participant!
If you encounter problems during the experiment, do not hesitate and email us. We will be happy to help.
Persons with visual impairments using full-screen magnifying glasses are at a disadvantage with respect to computer interfaces, because the magnification does not allow you to see the entire screen at once. In this regard, users of full-screen magnifiers suffer from such problems as disorientation and the lack of information about the content that is not currently visible on the screen. Many commercial solutions have these disadvantages, relying, first of all, on the automatic panning of the screen magnifier, which only contributes to disorientation and takes control from the user.
We offer a solution for visualization based on this issue. We base our research on existing off-screen visualization literature. We develop a predictive model of the task execution time with visualization of pointing to targets of various sizes and located at different distances. The data from this experiment will serve as a starting point for the development of more complex visualization systems for screen magnifiers.
Note: Mr. Wilson does not read comments on Habrahabr and does not even know Russian, so all questions and reports about the experiment should be sent to his email and must be in English. I propose to everyone at the end to send greetings from Habrahabr.Ru so that they recognize ours.
The original English language appeal is " Magnification Visualization Experiment ".
