等級 1：「大螢幕應用程式品質」指南的最高品質等級。
針對大螢幕差異化後，應用程式可打造出小螢幕裝置難以實現的使用者體驗。
應用程式經過大螢幕差異化後，使用者就能以簡單便利的方式，執行多工處理和拖曳操作。差異化應用程式支援摺疊式裝置獨有的功能，例如免手持模式，可提供其他裝置類型無法比擬的使用者體驗。
此外，這類應用程式提供與電腦不分上下的外接鍵盤、滑鼠和觸控板支援功能，還能全面支援觸控筆，讓觸控筆成為裝置體驗的重要一環。
注意事項
- 大膽創新
- 設計自訂版面配置和行為
- 讓應用程式脫穎而出
- 甘於平庸
- 設計時只考量一或兩種裝置類型
- 讓應用程式平平無奇

在高端裝置上提供出色的使用者體驗。提高使用者的效率和滿意度。
方式
如需進階觸控筆支援功能的操作說明，請參閱「觸控筆」總覽。
提供滑鼠、觸控板和觸控筆互動的背景資訊。
適用指南：LS-P1
意義
應用程式會顯示自訂游標，例如文字專用的 I 字形游標、用於可調整面板的大小調整控點，以及處理程序時顯示的旋轉圖示。
