Sensors Data Collector

收集加速度計和其他傳感器數據，並讓您實時標記它。

Sensors Data Collector lets you collect data from various sensors from your device (including accelerometer, magnetometer, gyroscope etc), and lets you label/annotate this data in real time when collecting it. The collected data is saved to CSV files on your device's local storage, and can be easily used for training machine learning algorithms or for other artificial intelligence tasks.

Sensors Data Collector acquire high precision data of all the sensors available on your Android phone or Tablet, and shows real-time graphs and charts of the data being collected. The app allows you (during the data collection process) to select which activity is being performed and allow you switch between activities (user defined labels). This option allows you to save high quality labeled data that can directly be used in your experiments, demonstrations, and to train machine learning and data mining algorithms.

The app also allows you to visualize the saved data, by plotting in on a lines chart as well as a 2-simensional scatter plot after performing PCA (for dimensionality reduction).
