    About this experiment

    Help us improve screen magnification technology for the visually impaired! We are conducting an experiment and your participation can provide us with valuable data that will be sent to developers of new products that make life easier with screen magnifiers. 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 using the instructions below and email the results to Principal Investigator Jeffrey A. Wilson .

    How to take part

    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, which 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 member!

    If you encounter problems during the experiment, feel free to email us. We will be happy to help.

    Study Details

    Persons with visual impairments using full-screen magnifiers are at a disadvantage with respect to computer interfaces, since the increase does not allow you to see the entire screen at once. In this regard, users of full-screen magnifiers suffer from problems such as disorientation and lack of information about content that is not currently visible on the screen. Many commercial solutions have these drawbacks, relying primarily on automatic panning of the magnifier, which only contributes to disorientation and takes control from the user.

    We offer a visualization solution based on this issue. We base our research on the existing literature on offscreen visualization. We are developing a prognostic model of task execution time with visualization of indications of 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 the Russian language, so all questions and reports about the experiment should be sent to his e-mail and must be in English. I invite everyone at the end to send greetings from Habrahabr.Ru, so that they recognize ours.
