- Download and install the drum machine or sequencer for your OS
- Make sure you have a camera plugged to your computer (webcam, or DV camera should also do)
- If it is the first time you use the system, a dialog box will appear asking you to log in.
- In the login dialog enter username and password (you need to create an account on the registration page) and click on the activate button
- The d-touch application will now launch; on OS X a configuration dialogue for the camera will pop up, please select the appropriate options or leave the defaults, and click on OK
- If necessary or appropriate, you can configure various parameters related to the audio card and the webcam by opening the preferences dialog
- Adjust the camera and board positions to make sure that all the markers in the corners are in view
- Fix the board to the table using some tape, if possible
- Adjust the camera focus and the light in the room so that the four calibration markers at the corners of the board are recognized and highlighted. It is best if they are stable, but it can be ok if they blink a little
- The d-touch application will give feedback if the calibration markers aren't visible.
What are calibration markers? They're the rectangular shapes in the 4 corners of the board, they help d-touch workout the correct position of blocks on the interface.
- Follow the onscreen instructions until the d-touch application is properly calibrated.
This could involve positioning the board correctly; Toggling a debug display which helps you to understand how lighting can affect marker recognition; Or perhaps toggling blur will help d-touch recognise markers by reducing the noise or graininess some webcams produce.
- Place some blocks on the board and check that they are recognized and highlighted. It is best if they are stable, but it can be ok if they blink a little
- Enjoy using your new tangible interface application!
