沒有螢幕的電腦

在我們使用電腦的習慣中，一定有個螢幕做為系統I/O的介面，但是，從USPTO的公告資料中發現：Apple剛通過一個專利，在行動裝置中內建智慧投影系統，其思維完全跳脫出當前電腦的框架。
它內建了LED或雷射投影系統以及揚聲器，並搭配無線滑鼠與鍵盤，同時還採用無線充電，省掉了電腦週邊大多數的附加線材，不但可以隨身攜帶，還能放置在各式各樣的空間內。
藉由加速計(accelerometer)、環境光源感測器(ambient light sensor)以及深度感測器(depth sensor)，可搜集投影表面的顏色、質感等特徵，據此產生最佳化的影像。

Title : Computer systems and methods with projected display
Filing Date : 2008.9.26.
Issue Date : 2013.12.17.
Abstract :
Computer systems and methods may provide a projection display as a primary visual output. In particular, a computer system may include an integrated projector output. Such a computer system may be substantially or even entirely externally wire-free. Methods of image processing may involve a computer system with an integrated projector output. Such methods may involve using raw presentation data for image processing, including adjustment and/or correction for brightness, color and/or geometry artifacts generated from aspects of the projection surface (such as geometry, texture, color or the like), the surroundings (such as ambient light), the relation of the computer system (or integrated projector output) to the projection surface (such as distance, orientation or the like), and/or the relation of a user/viewer to the projection surface (such as viewing angle, distance or the like).
