G-Field Recorder 與 Horizontal Accelerometer 使用情況與統計
G-Field Recorder is an easy-to-use and powerful data acquisition and analysis system for iOS device deployments. G-Field Recorder logs, plots, and replays:
- 3-axis acceleration fields
- 3-axis rotational displacements
- Ground speed
- Altitude
- Distance
- Displacement
- Course
Use this app to assist your analysis of experiments, sports performance, drone behaviors, land vehicle and watercraft actions, security applications, structural behaviors, and more.
All of your data is logged on your device, where you may retain it indefinitely, share, or delete the files of your choosing.
All data files are easy to export in CSV format via AirDrop and other methods (e.g. Slack, email, LinkedIn ...) available on your device.
Developed for NASA payloads, G-Field Recorder is resistant to data loss from impacts, continuously saving your data to permanent storage in case of a severe upset event that damages your device (e.g. you crash your drone).
Features:
- Logs and plots of motion data:
-- 3 Axis Acceleration Field
-- 3 Axis Rotations (Pitch, Roll, and Yaw)
- Virtually unlimited recording time.
The collected data is automatically stored in as many sequentially indexed files as required, up to about 5 MB per file (for easy search and review). Data storage capability is up to the max storage availability on the device.
- Programmable data acquisition control:
- Relative start time
- Absolute start time
- Relative stop time
- Acceleration reference frame is configurable:
-Choose to ignore or sense gravity
- Select reference frames: Proper, Fictitious, or Coordinate acceleration
- Remote control and monitoring via Apple Watch:
- Apple Watch can start and stop data collection, overriding any device-programmed start and stop times
- Apple Watch can set the acceleration reference frame
- Set sampling frequency from vanishingly small (e.g. 0.001 Hz) up to 100 Hz
- Computed averages and extrema of are automatically logged for all recorded motion data
- Rewind and instant playback of recorded data
- Text notes and an image can be added to each stored data file
- Selectable animated icon graphics
GPS Package In-App Purchase (recommended )
-- Ground Speed, Course, Altitude
-- Distance & Displacement
-- Illustrated path overlayed on Apple Map

"Horizontal Accelerometer" is a tool that displays horizontal acceleration in real time.
(Application)
- Measures acceleration, deceleration, and lateral G of automobiles. The acceleration value in the direction felt by the driver is displayed. Color zones and sounds make acceleration values easy to understand even while driving.
- Rigidity evaluation of table legs
- The horizontal accelerometer allows engineering students to actually measure and feel the acceleration value, which is useful for understanding the equation of motion.
(How to use)
1. Fix the iPhone on the object to be measured. No need to fix it horizontally. When measuring the acceleration of a car, fix the iPhone on the dashboard at an angle that makes it easy to see the screen and so as not to shake. When evaluating the rigidity of the table legs, place the iPhone on the table surface, and if the iPhone slips when the table is shaken, fix it with tape.
2. Tap the "Calibration" button, then tap the "Calibrate" button. The display of the horizontal acceleration value starts. In the case of a car, please stop the car on a horizontal road and then calibrate.
(Screen display)
- The number at the top of the screen is the value of real-time horizontal acceleration.
- "Peak hold" is the peak value of horizontal acceleration. Reset after the set time.
- ”Max" is the maximum value of horizontal acceleration. Reset with the “Reset Max" button.
- Acceleration values can change to red and yellow depending on the threshold.
(Calibration dialog)
Tap the "Calibration" button to bring up the calibration dialog.
- "Calibrate": Executes calibration in the current fixed state.
- ”Recall Calibration": Recall the saved calibration.
- "Save Calibration": Save the current calibration.
- "List of useful apps": Displays a list of useful apps.
(Setting dialog)
Tap the "Setting" button to bring up the setting dialog.
- "List of useful apps": Displays a list of useful apps.
- “Setting": A setting window appears.
(Setting window)
- "Color zone(value(G) or more)": Color zone thresholds, color on/off, and sound on/off can be set. The default thresholds are Red 0.40 and Yellow 0.30.
- "Peak hold time(s)": Peak hold time can be set. Default is 10.
- "Harshness cut filter": Harshness cut filter on/off can be set. "Harshness" means impact vibration.
- "Desensitization(%)": Desensitization rate can be set. Default is 0.
(Remarks)
- This app works on iPhone and iPad.
- Tilting the device tilts the calibrated horizontal plane, so measurement error occurs.
- The developer assumes no responsibility for any loss or claims by third parties which may arise from the use of this app.
