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 comprises light-field emitters. In other embodiments, the rotating structure is illuminated by an external (e.g., non-rotating) light source.
Claims17
A method for displaying an image, the method comprising:
- determining a notification of a state of a wearable augmented reality display device;
- driving a plurality of fan blades of a fan assembly such that the plurality of fan blades are positioned at rotation angles as a function of time;
- mapping image data associated with the image to a plurality of light sources based on the rotation angles, wherein the plurality of light sources are positioned on the fan blades;
- communicating a signal indicative of the notification to a controller;
- illuminating a fan assembly based on the signal according to the mapped image data;
- and
- displaying the image using the fan assembly, wherein the image is indicative of the notification, and
- wherein the fan assembly is implemented in the wearable augmented reality display device.
A fan assembly for displaying a representation of an image, the fan assembly comprising:
- a rotatable structure with a plurality of fan blades;
- a motor configured to rotate the plurality of fan blades of the rotatable structure;
- a plurality of light sources disposed relative to the rotatable structure;
- a non-transitory memory configured to store image data to be displayed by the fan assembly;
- and
- a processor operably coupled to the non-transitory memory, the motor, and the plurality of light sources, the processor comprising executable instructions to:
- determine a notification of a state of a wearable augmented reality display device;
- illuminate the fan assembly by actuating the plurality of light sources on the plurality of fan blades of the rotatable structure;
- and
- display an image with the image data using the fan assembly, wherein the image is indicative of the notification, and
- wherein the fan assembly is implemented in the wearable augmented reality display device.
A wearable augmented reality display device comprising:
- a display system positioned in front of the eyes of a user;
- a fan assembly comprising a rotatable structure with a plurality of fan blades, a motor configured to rotate the plurality of fan blades of the rotatable structure, and a plurality of light sources disposed on the rotatable structure;
- a non-transitory memory configured to store image data;
- and
- a processor operably coupled to the non-transitory memory, the display, and the fan assembly, the processor comprising executable instructions to:
- determine a notification of a state of the wearable augmented reality display device;
- illuminate the fan assembly by actuating the plurality of light sources on the plurality of fan blades of the rotatable structure;
- and
- display the image with the light sources on the fan assembly, wherein the image is indicative of the notification, and
- wherein the fan assembly is implemented in the wearable augmented reality display device.
