Simple experimental application for gathering data for later analysis in a sensor experiment on Android at Ubiquitous Computing (slo. Vseprisotno Računalništvo).
Goal of the experiment is to prove or disprove the ability to accurately sense a shot has been taken with a gas airsoft pistol using a regular Android phone and its on-board sensors (microphone and linear accelerometer).
Additionally it publishes live capture data via MQTT.
- Run application
- Set experiment name (optional)
- Toggle
Captureswitch and take a shot when it displays "Fire!" - Toggle
Captureswitch when enough data was captured - Experiment data saves to
/storage/emulated/0/Android/data/com.jonpas.sensexp/files/ - Copy captured data from
/storage/emulated/0/Android/data/com.jonpas.sensexp/filestoanalysisfolder - Analyse by following the analysis instructions below
Requirements:
Simple Python script to plot audio and linear accelerometer data for further analysis (analysis folder).
Setup:
