Ideas for Areas to Explore

Quick Draw Duo

  • Add some winning and losing sounds.
  • Use the accelerometer to change the game to one with a physical draw.
  • Find some other uses for a pair of synchronised CPB, e.g.  light shows, stereo/spatial audio playback.
  • Technical challenge 1: increase the robustness of the communication, e.g. make it recover from transient connectivity issues; match request and response with a suitable identifier.
  • Technical challenge 2: understand and set the connection interval for Blutetooth LE GATT transactions and factor this into the design of the board syncronisation process.

Reaction Timer

  • Add a cheat detector to the reaction timer to highlight impossible times and early presses.
  • Use the NeoPixels to show the reaction time graphically.
  • Increase the complexity of the visual (e.g. different colours, odd vs even) and auditory (e.g. different pitches) stimuli to investigate the additional delays from discrimination.
  • Investigate tactile reaction time with some sort of actuator controlled by the CPX/CPB board.
  • Examine any effect of using peripheral vision and lower brightness settings on reaction time.

Both

  • Add an announcement of each time or the fastest time using sound samples for each digit.
  • Independently verify the reaction timing - many smartphones offer high fps video recording in the form of a slow motion mode.
