Mode selection

After signing in with Google credentials, the app will feature two modes; an experimenter mode and a subject mode.

Subject Mode - Step 1

In the subject mode, the app will display the existing studies in Google Drive. Basically, each folder in Google Drive is considered a study.

Subject Mode - Step 2

M-Interface builds a graphical control screen to keep track of the unprocessed subjects per group. The experimenter can select one of the study groups to proceed.

Subject Mode - Step 3

Then, the experimenter selects a blocking variable (e.g. age group, gender).

Subject Mode - Step 4

Next, the experimenter selects a subject and taps the start button.

Subject Mode - Step 5

Once a subject is selected, the M-Interface switches to a graphical screen that controls the execution of the experiment for this particular subject. In the course of the experiment, the subject either enters textual data (e.g., questionnaire) or undergoes treatments. When it is time for the subject to do data entry, the M-Interface brings up the relevant questionnaire. When it is time for the subject to undergo a treatment, it instructs her/him to return to the operational theater and perform accordingly.

The M-Interface notifies Subject Book, a truly comprehensive data management system that treats data as the incorporation of the scientific method and its products, when a text entry session is complete, and Subject Book notifies the M-Interface when a treatment session is complete. This way, both the M-Interface and Subject Book are in sync with respect to experimental progress.
