  • USABILITY AN INTRODUCTION BY CHRIS BURKE An intuitive layout provides meaning when we can’t read it!
  • USABILITY AN INTRODUCTION BY CHRIS BURKE An intuitive layout makes the designs intent obvious
  • Efficiency: how quickly can users perform tasks after learning the design USABILITY AN INTRODUCTION BY CHRIS BURKE
  • USABILITY AN INTRODUCTION BY CHRIS BURKE Chunking timely tasks into smaller parts improves user efficiency
