Electronic devices with camera-based user interfaces

摘要

Electronic devices may include touch-free user input components that include camera modules having overlapping fields-of-view. The overlapping fields-of-view may form a gesture tracking volume in which multi-dimensional user gestures can be tracked using images captured with the camera modules. A camera module may include an image sensor having an array of image pixels and a diffractive element that redirects light onto the array of image pixels. The diffractive element may re-orient the field-of-view of each camera module so that an outer edge of the field-of-view runs along an outer surface of a display for the device. The device may include processing circuitry that operates the device using user input data based on the user gestures in the gesture tracking volume. The processing circuitry may operate the display based on the user gestures by displaying regional markers having a size and a location that depend on the user gestures.

主权项

1. An electronic device, comprising:
a first camera module having a first field-of-view; a second camera module having a second field-of-view that at least partially overlaps the first field-of-view; processing circuitry configured to operate the device based on user gestures performed in a portion of the second field-of-view that overlaps the first field-of-view; and a display, wherein the processing circuitry is configured to operate the device based on the user gestures performed in the portion of the second field-of-view that overlaps the first field-of-view by altering display content on the display based on the user gestures performed in the portion of the second field-of-view that overlaps the first field-of-view, wherein the display has a planar outer surface and wherein the first field-of-view has an extreme edge that runs along the planar outer surface of the display.
