0. General design guidelines

1. Splashscreen with Loading-Circle

2. Select Language (only at first start) 

3. Select between “Search existing users”, “create a new user” or select “Setting-Button” for other options

Right side shows pressed button “New User”. The active setting button (bottom right) leads to a new mask “Settings” in which e.g. the language settings, or other system settings (sound on/off, system-ID#, Import/Export DB, etc.) can be performed.

4. Main Menu bottom

5. Virtual Keyboard

For a better overview, the following figures show the keyboard with normal keys (background #00a1dd) in the upper area and the keyboard with pressed keys (background #ffffff) in the lower area. Sound effect for clicking buttons on the keyboard is the same everywhere.

The keyboard always opens when you press your finger into a data field and close if press the button “close keyboard”. Push your finger in a data field makes a special sound:

5.1 Virtual Keyboard (letters)

5.2 Virtual Keyboard (Numeric)

5.3 Virtual Keyboard (Special characters)

6. Search for existing User

To search for an existing user, click with your finger in the top field “Type name”. The keyboard goes up and you can enter the name you are looking for. As soon as the first letters are typed, a selection list with names corresponding to the search selection appears in the lower data field. Touching on the desired name takes over the desired user and you switch to the mask “Selection Trainings / Tests”.

On the right side there is a scroll bar that moves the selection list up or down.

The Home Button takes you back to (3.) Select between “Search existing users”, “create a new user”.

7. Create new User and Selection Trainings/Tests

The user can access this mask via the “Create a new User” option (Mask 3.) or via the “Search existing users” mask (Mask 6.) In the latter option, the data fields are already filled in with user data.

Note and for discussion: The field “Sex” should not contain a preselection and should not be mandatory. So we can make it possible for a discussion currently ongoing in Europe to introduce a third sex (transsexual). The selection of no gender would then mean synonymous to the selection transsexual.

8. Manual mode / Initials settings

9. Hardware Preparation

If you change from “Initial Settings” to the mask “Hardware Preparation” a device self test starts. The top row shows the result of the self-test. If the button is red, there is a malfunction – with a green display everything is ok.

At the same time, the window on the left side visualizes the placement of the pulse oximeter on the finger. Underneath a red notification button shows that the sensor has no connection. As soon as the sensor is in contact, the advisory button changes to green and signals that the sensor is successfully connected. The measured SpO2 value is then displayed in the illustration window.

The window in the middle shows the correct fit of the breathing mask and the current oxygen level.

The window on the right side shows the ECG and the connection of each ECG electrode (except for black RA). Malfunction is highlighted in red.

The user can go to the next mask with the button “Next” and starts the trainings-session by pressing the button. The NEXT-Button is disabled as long as hardware preparation successful finished.
With the button “Back” the user gets back to the mask “Initial Settings”.
