Device Sensor Test Detailed Guide: A High-Precision Checker Born from Developers and Its Applications
Our familiar smartphones and tablets have built-in "accelerometers" and "gyro sensors" to detect motion. These sensors play a crucial role in realizing various functions such as automatic screen rotation, game operation, and step counting in fitness apps.
However, in the field of app development, we may face problems such as "the sensor does not respond correctly." This app, "Device Sensor Test," is a high-precision checker born to solve such problems for developers themselves.
1. Development Background: A Unique Strength to "Visualize" Invisible Movements
This app was originally born in the process of developing another app that uses the accelerometer of a smartphone. During development, a problem occurred where the sensor did not react at all, and in order to investigate the cause, it was necessary to directly observe the raw movement of the sensor itself.
From this experience, this app was developed as a "tool that allows anyone to easily check the movement of the sensors built into jejich smartphone in real time." Unlike other general apps, since it is a tool born from the needs of the development site, it has a unique strength in the accuracy and immediacy of the display.
2. App Functions and Mechanism
"Device Sensor Test" is a simple web application that displays (visualizes) the movement of the sensors installed in your smartphone or tablet as numerical data on the screen.
Installed Sensors
- Accelerometer: Detects the tilt and linear movement (such as vibration) of the device on three axes: X, Y, and Z. In a stationary state, you can check the effect of gravitational acceleration (about 9.8m/s2).
- Gyro Sensor: Detects the rotating motion and angular velocity of the device, and displays which axis it is rotating around and at what speed. It is useful for detecting more complex movements.
How to Use (How to Use the Tool)
Just access the app page and tap the "Allow Sensors" button, no complicated settings are required. Real-time display of sensor data will start immediately.
Operating Environment and Debugging Information
- This tool uses the functions of a web browser (Web API).
- Recommended environment: Google Chrome browser
- Debugged environment: Chrome and Android devices
- Note: Depending on the browser or OS, reading some sensor data may be restricted.
3. User Benefits and Diverse Applications
This app can be used for various purposes as follows.
- As a debugging tool for developers and creators: When implementing functions that use sensors on websites and apps, you can quickly check whether the hardware is operating normally.
- For diagnosing sensor failures in devices: When you feel that "the screen of my smartphone does not rotate properly recently" or "the reaction of the game is strange," you can use it for a primary check of whether the sensor is physically broken.
- As a simple level: By referring to the value of the Z-axis of the accelerometer, it can be used as a simple level when installing furniture or doing DIY work.
- As a free research or learning tool: It can also be used as a learning tool for capturing physical movements as data, such as observing "vibrations" around you numerically.
4. FAQ (Frequently Asked Questions)
Q: The sensor does not react at all. Is there any troubleshooting?
A: If the sensor does not react, the following causes are mainly considered.
- Browser access permission: When you tap the "Allow Sensors" button, access to location information and device motion may be denied on the browser side. Please check your browser settings.
- OS restrictions: Some mobile OSs, such as iOS (iPhone/iPad), may restrict sensor access from external web pages from the viewpoint of privacy protection.
- Use outside the recommended environment: This app has been debugged in the Chrome and Android environments. If you use a different browser or OS, some functions may not work.
Q: Are there any future update plans?
A: Yes, in addition to the current accelerometers and gyro sensors, we plan to add functions to read other sensors derived from mobile devices, such as illuminance sensors and proximity sensors. This will enable a more comprehensive device check.
Q: Is commercial use possible? Also, please tell me about the license and terms of use.
A: This app can be used for commercial purposes regardless of whether it is for individuals or corporations. No special permission is required for use.
