PHONE CASE FOR TRACKING AND LOCALIZATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240137436 titled 'PHONE CASE FOR TRACKING AND LOCALIZATION
The abstract of the patent application describes a case for a portable device, like a smartphone, that includes light sources such as LEDs. These light sources can be detected and tracked by a head-worn augmented or virtual reality device. The light sources may emit infrared light and be located at the corners of the case. Computer vision techniques are used to determine the relative pose between the smartphone and the head-worn device based on images captured by the head-worn device that include light from the light sources. User input can be provided to the head-worn device based on relative movement between the smartphone and the head-worn device, as well as touch input on the portable device. In some cases, the case is powered inductively from the portable device.

Prior Art: There may be prior art related to computer vision techniques for tracking and detecting light sources in augmented or virtual reality environments.
Frequently Updated Research: Research on computer vision algorithms for improved tracking and detection of light sources in augmented reality environments may be relevant to this technology.
Questions about Light Source Detection Technology: Question 1: How does the inductive power transfer from the portable device to the case work? Answer: The inductive power transfer involves transferring power wirelessly through electromagnetic fields between the portable device and the case.
Question 2: What are the potential limitations of using light sources like LEDs for tracking in augmented reality environments? Answer: Potential limitations may include interference from other light sources and limitations in tracking accuracy in certain lighting conditions.
Original Abstract Submitted
a case for a portable device like a smartphone includes light sources such as leds, which, when illuminated, can be detected and tracked by a head-worn augmented or virtual reality device. the light sources may be located at the corners of the case and may emit infrared light. a relative pose between the smartphone and the head-worn device can be determined based on computer vision techniques performed on images captured by the head-worn device that includes light from the light sources. relative movement between the smartphone and the head-worn device can be used to provide user input to the head-worn device, as can touch input on the portable device. in some instances, the case is powered inductively from the portable device.
