A short outline of input devices and the implementation of a graphical user interface is given:

• Physical input devices used in graphics
• Virtual devices
• Polling is compared to event processing
• UI toolkits are introduced by generalizing event processing

 
• Physical Devices
• Virtual Devices
• Device Association
• Device Input Modes
• Application Structure
• Polling and Sampling
• Event Queues
• Toolkits and Callbacks
• Example for Discussion
