What is Device Action Log Analyzer?

Analyze time, acceleration, and orientation angle CSVs to calculate resultant acceleration, sampling interval, each axis range, and peak events that exceed thresholds. ToolHub places the core computing entirely within the browser, allowing immediate use on both desktop and mobile devices, without the need to register an account or send content to the backend.

How to use this tool?

  1. Enter the data according to the field prompts and select the required processing method.
  2. Click "Process Now" to view the results, indicator summary and necessary error messages.
  3. After confirming that the content meets actual needs, you can copy the results or download them into files for further use.

Suitable use cases

Mobile phone sensing QA, interactive prototypes, drop sample research and device log debugging. All processing is completed in the current page, which is especially suitable for workflows that do not want to post internal data to remote services.

Interpretation of results and precautions

Peak events are only marked according to the user's threshold; the results are affected by sensor calibration, coordinate system and sampling rate, and cannot be used as a safety or medical judgment. Tools will validate basic input formats and provide readable error messages, but production environments should still be reconfirmed against source specifications, business rules, or professional requirements.

Browser and device support

Device Motion Log Analyzer supports current Chrome, Edge, Firefox, and Safari releases. Mobile and desktop layouts use the same validation rules documented on this page.

Frequently Asked Questions

Will the Device Action Log Analyzer upload data to the server?
No. Tool functions are executed directly within the current browser tab, and input and generated results will not be uploaded or saved by ToolHub.
What usage scenarios is the Device Action Record Analyzer suitable for?
Mobile phone sensing QA, interactive prototype, drop sample research and device log debugging
Do I need to install software before using Device Action Log Analyzer?
No need. Use a desktop or mobile browser that supports modern JavaScript, and no account is required.
What are the limitations of this tool?
Peak events are only marked according to the user's threshold; the results are affected by sensor calibration, coordinate system and sampling rate, and cannot be used as a safety or medical judgment.
Is manual inspection required after the results are generated?
Needed. Tools can assist with calculations, conversions, or formatting, but before going online, importing data, or making business decisions, the results should still be reviewed according to actual specifications.

Reproduce the built-in example

Start with Action peak threshold m/s² = 13; Motion CSV = time,ax,ay,az,alpha,beta,gamma 0.000,0.2,0.1,9.8,0,5,2 0.016,0.4,0.2,9.7,1,6,3 0.032,8.0,2.0,11.0,4,12,8 0.048,0.3,0.1,9.8,5,13,9 0.064,-6.0, then run Device Motion Log Analyzer. Change one input at a time so the effect on the result remains traceable.

After validating action peak threshold m/s², motion csv, the page displays its result in the output workspace and enables the relevant copy or download action.

When to use it and how to interpret the result

Mobile phone sensing QA, interactive prototypes, drop sample research and device log debugging. All processing is completed in the current page, which is especially suitable for workflows that do not want to post internal data to remote services.

Limits and checks before use
