Abstract
Apparatus and methods for displaying an image by a rotating structure are provided. The rotating structure can comprise blades of a fan. The fan can be a cooling fan for an electronics device such as an augmented reality display. In some embodiments, the rotating structure comprises light sources that emit light to generate the image. The light sources can comprise light-field emitters. In other embodiments, the rotating structure is illuminated by an external (e.g., non-rotating) light source.
Claims20
A method for displaying an image, the method comprising:
- determining a notification of a state of a wearable augmented reality display device;
- communicating a signal indicative of the notification to a controller;
- illuminating a fan assembly associated with the wearable augmented reality display device based on the signal;
- and
- displaying an image using the fan assembly, wherein the image is indicative of the notification.
An augmented reality device comprising:
- a wearable display system positioned in front of eyes of a user;
- a fan assembly comprising a rotatable structure, a motor configured to rotate the rotatable structure, and a plurality of light sources disposed relative to the rotatable structure;
- a non-transitory memory configured to store image data;
- and
- a processor operably coupled to the non-transitory memory, the display system, and the fan assembly, the processor comprising executable instructions to:
- determine a notification of a state of the wearable display system;
- illuminate the fan assembly;
- and
- display an image using the fan assembly based on the image data, wherein the image is indicative of the notification.
