cybertisch in action

Installed software

• Ubuntu 16.10
• reacTIVision: computer vision framework for tangible interactive surfaces
• TUIO: a common protocol and API for tangible multitouch surfaces which allows the transmission of an abstract description of interactive surfaces, including touch events and tangible object states.
  • Java Client
  • C++ Client
  • Simulator for development without the hardware

Known issues

• the firmware is a little bit fragile: "conclusion: a firmware which trashes its own EEPROM due to a single wrongly set direction bit is perhaps a little fragile"
• don't use the Unity UI session because their touch/gesture support meddles with the operation and can even freeze
  • when using LXDE you have to powerdown the table using the shell for now
• yamaarashi symbol detection doesn't work although amoeba symbols work fine
• the table is a little bit sensitive to light (see the "Venue Readiness Guide" below for the finer details)
• don't turn the backlight down, this also confuses the table :)
• give it some time to warmup after powering on
