Concepts (2)• Web UIs• Don’t make me think• Nielsen’s top 10 mistakes on the web• Game UIs• Controls and dialogs• Usable security

– Usability and security do not have to conflict– Most security experts do not understand usability– Usability is not the same as UI design– Usability is necessary to achieve security– Making access harder for legitimate users does not improve

security– Usable security is about pain points, not process

• >= 98 : A+ – Probably only one A+ per class• > 93 : A• > 90 : A-• > 86 : B+• > 80 : B• > 75 : B-• > 65 : C

• I will “slide the line” down to an appropriate “break point”
