15 可用性團隊決定Creating Baseline Windows 3. 1 使用者表現量測 (profiling) 開啟隱藏程式: 9. 5 mins 滑鼠使用問題 (double clicking) 所視僅所得 (What You See Is ONLY What You Get) 什麼選單是看不到的? Windows 3. 1操作表現不佳 重新設計Windows 95 GUI
Design 1: 為初學者建立專屬介面 16 • Function accessibility • Different from Win UI • May learn twice
Design 2: Minimized Window 18 “Plate” visualization for minimized windows Couldn’t see what programs are open Win 3. 1
