Size test

This application is designed to assess how quickly the user reacts to changes in the size of an object. Users can select one of the test modes: 'Increasing the object', 'Decreasing the object', 'Decreasing or increasing the object'.

When the user observes a change in the size of an object, the user must break contact with the device screen. The recorded test time reflects the user's ability to perceive the change in object size.

Once the test is completed, the results are tested for normality of distribution (Shapiro-Wilk test). If the values deviate from the law of normal distribution, the program analyzes the data sets, removes the worst value and adds an additional attempt. In the program settings you can select the number of attempts - from 10 to 30. The choice of the number of attempts depends on the performer's age and professional activity.

In addition, in the program settings the user can save a backup copy of his measurements in JSON format anywhere (Save backup), add measurements from another device (Add backup), replace already saved measurements with new ones (Replace backup) or delete all data (Delete all data).

This application is intended to be used by athletes and teachers in specialized educational institutions for scientific research.
