First, using SENSOR API of tizen-studio, I checked what kind of functionality my watch can support.
As a result, among the 24 different sensors, Samsung gear s3 supports 10, and there are 6 sensors related to the gesture capture, colored in blue.
There are some sensors working similarly, like Accelerometer and Linear Acceleration sensor, so I need to decide which one would be better to interpret user’s gestures.

3. ‘17 Fall CS2310 Project – Milestone2 WEONJI CHOI (LUCIA)
Get Sensor data
And I made an application that reads and transmits sensor data.

4. ‘17 Fall CS2310 Project – Milestone2 WEONJI CHOI (LUCIA)
Test using emulator
I tested my basic application using emulator provided by tizen studio,
After that I launched the application on real smartwatch and tested it.

5. ‘17 Fall CS2310 Project – Milestone2 WEONJI CHOI (LUCIA)
Test using real device

6. ‘17 Fall CS2310 Project – Milestone2 WEONJI CHOI (LUCIA)
Next Stages
What kind of sensors can read human arm’s movement most appropriately?
What kind of existing or new gesture library can be used?
Build a user interface to show results to the user.
These are my next steps.
I need to decide
