Personal interactive overhead projection inflight entertainment system

摘要

In a personal interactive overhead projection IFE system, an overhead projector associated with a passenger's seat projects video onto a passive substrate attached to the seat. The passive substrate may be a tray table or a dedicated video projection screen. The passenger sitting in the seat controls the projected video by positioning his or her finger or making hand gestures proximate the passive substrate. An overhead camera records the hand actions. An overhead processor interprets the hand actions and controls the projected video based on the hand actions. The system provides highly desirable personal and interactive features while obviating the need for seatback video display units or passenger control units.

主权项

1. A personal interactive overhead projection inflight entertainment system, comprising:
a seat-mounted tray table adjustable between a non-deployed position and a multiple of deployed positions; an overhead projector configured to project video onto the tray table in any of the deployed positions; an overhead camera configured to record the tray table in any of the deployed positions; and an overhead processor configured to determine from a recording made by the overhead camera current deployed position data for the tray table and further determine, using the current deployed position data, a distortion to be applied to video projection images which improves visual quality of the video projection images as displayed on the tray table, whereupon the distortion is applied to the video projection images and the video projection images are projected by the overhead projector onto the tray table.
