Apple has filed for a patent (number US 20240275210 A1) for an “HMD With Charging Device” that involves charging the Vision Pro from a wearable device.
Currently, the spatial computer is powered by a standalone battery pack that connects via a cable to the Vision Pro. The battery lasts for about two hours. For uninterrupted usage longer than that, the spatial computer must be connected to a power outlet.
About the patent filing
In the patent filing Apple notes that a primary challenge when developing head-mounted displays such as the Vision Pro, particularly head-mounted displays that have small form factors, is achieving a suitable battery life while still maintaining functionality and a socially acceptable shape and size. Performing the necessary computing functions, while still making the head-mounted display stylish and light enough that a user could wear the device for an extended period of time demands solutions that aren’t currently available.
Given the power consumption needs of head-mounted displays and current battery technology, a user may remove and charge the device several times a day, often interrupting use, and causing inconvenience to the user. What’s the solution?
The patent filing says that juicing up a Vision Pro from a “wearable device” is an idea. However, it’s unclear what such a device might be. AirPods, Apple Watches, and a rumored Apple Ring wouldn’t seem to offer nearly enough power. Does Apple has another wearable device in mind? The tech giant has applied for, and been granted, patents for “smart clothing” so perhaps that’s a possibility.
Summary of the patent filing
Here’s Apple’s abstract of the patent filing: “According to some aspects of the present disclosure, a wearable system can include a head-mounted display having a first battery and a first connector electrically coupled to the first battery. The system further including a wearable audio device having a second battery and a second connector electrically coupled to the second battery. The second connector configured to connect with the first connector to transfer power from the second battery to the first battery.”
