LOCGET is a logger that can record iPhone location information, sensor values, volume, video (video or photographs) simultaneously. Use the iPhone research and development, physics of physics at school, as a reminder, such as climbing, driving, cycling, travel, etc.
[Recording item]
You can record the following values ​​(how many times measured per second). These values ​​can be acquired in the background.
(1) Position information (latitude and longitude of the global geodetic system.)
(2) Moving speed
(3) Direction (true north standard, magnetic north standard)
(4) Acceleration (3 axes)
(5) Gravity (3 axis)
(6) Angular velocity (3 axes)
(7) Posture (Yaw, Pitch, Roll)
(8) Death pressure
(9) Advanced (difference from measurement start point)
(10) Magnetic (3 axes)
(11) Volume (This Information Is Just for Reference Purposes.)
(12) Videos (recording in synchronization with sensor values. ※ shooting is completed at the time of background migration.)
(13) Photos (ADDFLAG 'button recorded when pressing)
[Function during measurement]
• Press the flag button during measurement to add a flag to the data. You can find that time quickly when checking data (for example, if you meet a stray cat while taking a walk), you can use a flag button.
· If you are setting to take a photo, press the flag button to shoot a photo.
(By default, the 'add flag' button is not displayed. If you want to display, you need to change the settings.)
[Measurement result file]
• The measurement result is created a folder with the name of the measurement date and time for each measurement and is recorded as a CSV file. The recorded CSV file can be edited as it is with the iPhone app. Of course, it is possible to output external output with Mac (using Finder) and PC (iTunes).
• If you get location information, a simple KML file is created.
• Videos are saved in MP4 format.
· Photos are saved in JPEG format.
※ Videos and photos are not recorded by default. When recording, you need to change the settings.
[Confirmation of measurement results]
· You can check the location information acquired in the app on Apple Map. It is also possible to display in a simple line drawing.
Position information, each sensor value (graph), and video data can be confirmed synchronously (Verify the slider or press the play button). If you shoot a photo, you will receive a photo when you reach the photo taken.
• The time when the flag button is pressed is added on the graph.
• You can display the value defined by the user by adding a row to the CSV file in synchronization with location information or video. (For example, 3-axis acceleration power spectrum is calculated by Excel and added etc.)
[Preparation of measurement]
· Save the type of sensor to be recorded or the type of sensor displayed on the top screen, and switch quickly.
*** Please test before use. ***
• Depending on the performance of the iPhone, the frequency of acquisition of the specified sensor value may not be achieved.
· The larger the type of sensor value to be recorded, the higher the sensor value acquisition frequency, the larger the CSV file capacity.
· It is possible to specify whether to display and record the sensor value. You can save battery and file capacity.
· The more the number of sensor values ​​used and the number of sensor values ​​used increases, the more battery consumption
