Mode 4 – ERM Clicks
Mode 4 showcases ERM clicks and double clicks. Similarly to the LRA, compare the click with braking and
without braking and notice the sharper feel with braking.

Mode 5 – Concentration Game
Mode 5 is a game that incorporates the various LRA and ERM effects. This can be used to demonstrate
haptics in a real application.
To begin playing Concentration:
1. Press any of the large effect buttons.
2. The game will then count down.
3. Once the countdown completes, a button will light and an effect will play.
4. Repeat the pattern by pressing the same button.
5. After each successfully repeated pattern, the board will repeat the same pattern and add one
additional button to the sequence.
