wm4

The variable number of geometric shapes is briefly displayed on the screen. A user must remember how many geometric shapes were shown on the screen. After the time delay, the user must enter the number of geometric shapes that were previously displayed on the screen. At the end of the research the results are presented in the form of graphs and tables.

A form for changing basic application settings is included. You can adjust these settings: minimum and maximum number of geometric shapes displayed, number of items (tasks), the time interval before the stimulus, time interval of the stimulus, time delay, the type of geometric shape, the size of the geometric shape, monochrome geometric shapes or in color, position of the stimulus on the screen: full screen, half screen or 4 quadrants, application behavior before displaying the main stimulus.

wm4 - developer

If you need a wm4 application that uses a database on the server, you can use the wm4-developer version as a template. This template was created from the previous version of wm4 application (1.0).

Description: Before the survey, a user in the form template writes data that is stored in the database (the content of these data is variable). A number of dots (circles) are displayed briefly on the screen. A user must remember how many dots were shown on the screen. After the time delay, the user must enter the number of dots that were previously displayed on the screen. At the end of the research the results are presented in the form of graphs and tables. Also, statistical data from the database (for all users) can be displayed in the form of graphs and tables.

This template is only developed for the wm4 1.0 version of the program

The main features of the application are:

  • form template for user data entry (10 string type fields, 3 integer type fields, 2 float type fields)
  • built-in validation of user data (client and server)
  • php program code for interaction with the MySQL database (with create table)
