Haptic Analytics
This is where you can test, study, and compare your magnet implants!
-
The first tab is where you can start a test. You get rewards for testing daily!
-
You can tap one of your magnets listed here to proceed to the tests. ZINC will generate a short sequence of tests based on your previous analytics if any.
-
You can also switch from automatic to advanced to choose what test you want to perform and how much time you have. You can also select a wave type (sine, square, saw), if you're confused leave it to the automatic mode or go to the Haptic Lab and play around for a bit.
-Once started follow the instructions attentively! Always reply truthfully, it's science, not a school exam!
-
Head over to the second tab. Here you will see a large readout of your magnetometer. This is your device's magnetic sensor detecting the earth's magnetic field as well as any ambient interferences. Don't worry they are pretty low and won't even come close to your magnet's strength.
-
We now need to locate the sensor. It is more likely somewhere on the back of your Android device. Run your magnet along the surface and look out for a rise in the Tesla reading. Pinpoint the sensor's location.
-
Rotate your magnet against it until you're confident that you've reached a max value. This can take a minute of fiddling around.
-
Once done tap on the magnet you've been testing in the list below to save your result.
-
In the third tab you will find the analytics. All the data you've collected, broken-down in graphs and plots.
-
In the red and blue fields you can select the magnet(s) you would like to see data for. In the graphs data with red/blue color will correspond to the magnet of said color.
-
Below are toggles for the signal types you're interested in viewing. Similarly, they are color-coded cyan, magenta, and yellow.
-
Now that you've selected the magnets and wave types you can see the results appear in the graphs below.
Plots the smallest perceivable amplitude per frequency. In other words how faint of a signal you can feel. The lower the better.
Plots the smallest gap in amplitude you can feel per frequency. In other words how much resolution do you have in signal strength for a given frequency. Again lower numbers are better.
Plots the strength in Teslas of your implant at the skin surface over time. Here, higher numbers are usually better. If you take measurements regularly you might be able to see things like encapsulation and healing take place.
Tests are divided into "questions": each question being composed of a stimulus followed by a user feedback. Each question has a test type, wave type, and the appropriate parameters.
Usually, the user will proceed to answer a series of questions. The user is instructed on the test requirements and guidelines:
BEFORE YOU START
- Plug in your Lodestone
- Make sure your device's volume is all the way up
- Place your device down and get comfortable with your implant as close to the stimulator as possible without touching it.
- Regular breaks are strongly recommended.
For the test results to be reliable and optionally be shared please make sure you are NOT:
- Within two weeks of implantation
- In an uncomfortable ambient temperature, too cold or too hot
- Under the influence of any substance at any level. Including coffee, alcohol, drugs, and strong medicine
- Severely sick or injured, especially in the tested area
- Under extreme tiredness, stress, pregnancy, or other sense-altering states
Test results will be saved and visible locally. They can be exported and can optionally be shared to a public database for science.
For each question:
- Wait for user to tap a "Ready" button
- Render the haptic signal
- Show the question and answer buttons
- Wait for the user's choice
Results are saved independently for each question even when performed in a sequence.
An amplitude value is selected from the testable range.
A frequency value is selected from the testable range.
The frequency-amplitude pair is presented as follows:
[0.5s no signal] [1s signal] [0.5s no signal]
Then the user is presented with the question:
"Did you feel any stimulation?"
0 - "No"
1 - "Yes"
A frequency value is selected from the testable range.
An offset is selected from the testable range.
A fixed amplitude value (MAX_AMPLITUDE - (MAX_OFFSET / 2)) is selected.
The frequency-offset pair is presented in as follows:
[0.5s no signal] [1s amplitude + offset / 2] [1s no signal] [1s amplitude - offset / 2] [0.5s no signal]
or (random):
[0.5s no signal] [1s amplitude - offset / 2] [1s no signal] [1s amplitude + offset / 2] [0.5s no signal]
Then the user is presented with the question:
"Which stimulation was stronger?"
0 - "First"
1 - "Same"
2 - "Second"
Under development.
Under development.
-
Latest mode: Will display the latest result for each test and each wave type if available.
-
Average mode: Will average data per test and wave type from all results.
-
Optimized mode: Under development.
-
Custom selection will limit the processed results to the selected ones.
-
Wave type toggles will limit the processed results to the selected types.
