Tutorials

This section provides several tutorials on how to navigate in the application and how to perform the tests that are provided. You can find instruction on the following topics:

  1. Starting the application
  2. Viewing the in-app manual
  3. Performing the test for the game rotation vector
  4. Performing the test for the linear acceleration sensor
  5. See the rating of your device
  6. The ranking of the device
  7. Getting the reference pattern

Starting the application

The main menu of the app

When you start MEMS Score for the first time, you are greeted by the a welcome screen. If you wish, you can look at the provided manual or direktly resume to the application. If you skipped the manual but wish to see it later, refer to Viewing the in-app manual.

When you leave the welcome screen, you can see the main screen of the application from where you can navigate to the tests, the rating of your device, the manual and the ranking. You can also access the menu for the reference pattern from here.

Viewing the in-app manual

Menu for the manual

MEMS Score provides extensive instructions for the navigation in the application as well as instructions on how to perform the tests.
The general informations about the MEMS Score can be accessed from the start screen of the application . The screen you switch into shows a selection on topics you can select.

There are also instructions for the different tests. You can assess them when you select a test in the test screen and then select Show Instructions in the popup menu. The menu can be seen to the right.

Performing the dynamic test for the game rotation vector

For the dynamic rotation test you have to rotate and move the device above the reference pattern and fulfil the movements that are displayed at the screen of the device. Therefore you have to balance the orange marker on the reticule in the middle of the blue marker. The blue marker is moved by the application. You have to hold the device above the pattern in a way that the pattern is fully visible the while time and fills the whole image.

You can watch the following video to see, how the device should be handled for the test:

Note that at one point the reticule was tinted red because the operator did not move the device. The tinting of the reticule in the middle of the screen is an indicator that the desired movement was not made.

Test summary

MEMS Score displays the result of the dynamic rotation test. The first value is the score. It is the average angle in degree that the Game Rotation Vector differed from the actual rotation.
The second part, the stars, displays how well the sensors would perform in applications like augmented- or virtual reality.

Performing the test for the linear acceleration sensor

Graph shown during the test

The test for the linear acceleration sensor currently only consists of the static test. Therefore you have to place the device on a flat surface and not move phone until the test is finished

Test summary

MEMS Score displays the result of the test of the Linear Acceleration Sensor as soon as the static test ends. Again the results show two important values. The first value is the score. It is the maximal distance in centimetre that the linear acceleration sensor was wrong.
The second part, the stars, displays how well the sensors would perform in applications like augmented- or virtual reality.

See the rating of your device

Screen with the rating of the device

MEMS Score allows you to see the overall rating of your device once you have performed all tests. You can access the rating when you click the Rating option on the main screen.

The overall rating is only available when all tests were conducted. You need to conduct the test for static accuracy and dynamic rotation at least five times for each sensor speed. Tests that are not conducted are labelled with n/a

You can click on any of tests in this screen to access a more detailed rating of the sensor/test. You can als see here how often a test has to be conducted.

The ranking of the device

When you are in the Main Screen, you are able to access the ranking of your device. The ranking compares the results for your device with the results from other devices in the database.
Click the Show Ranking button on this screen to see the ranking of your device for the overall score.

Screen with the ranking of the devices

You can switch from the ranking for the whole devices to the rankings of the different sensors (e.g. the Linear Acceleration Sensor) when you click on the drop down menu on the top of the rankings screen.

Getting the reference Pattern

Open the raster options

You can download the pattern from the following link:

Download Pattern

MEMS Score also provides several ways to retrieve and print the reference pattern. To get to the option for the pattern click on the Reference Pattern option in the main screen.

The menu that opens provides you three options to get the pattern:

  1. Access the pattern with the shown link. You can download the pattern with any device from the link.
  2. Open Pattern as PDF opens a PDF file of the pattern in the devices PDF-Viewer. You can directly print it from here when a printer is connected to your device.
  3. Share the pattern with other applications of you device. This allows you to send the pattern e.g. via email or bluetooth.
