Handheld controllers with charging and storage systems
A system may include an electronic device such as a head-mounted device and a handheld controller for controlling the electronic device. The handheld controller may have a housing with an elongated shaft extending between first and second tip portions. The handheld controller may have power receiving circuitry configured to receive power from a power source. The power source may be incorporated into an electronic device such as a wireless charging dock or stick, a battery case, or a head-mounted device. The power source may supply power through terminals that form ohmic contacts with mating terminals in the finger device or may transmit power wirelessly using capacitive coupling or inductive charging arrangements. Magnets may be used to hold and align the elongated shaft of the handheld controller on the power source.
1. A head-mounted device configured to store a handheld controller for the head-mounted device, wherein the handheld controller has an elongated shaft, the head-mounted device comprising:
a main housing portion;
a display in the main housing portion that is configured to provide an image viewable from an eye box, wherein the image is adjusted in response to user input to the handheld controller;
a head strap configured to support the main housing portion; and
magnets in the head strap that are configured to hold the elongated shaft against the head strap.
2. The head-mounted device defined in claim 1 wherein the head strap comprises an inductive charging coil that is configured to supply wireless power to the handheld controller while the elongated shaft is held against the head strap.
3. The head-mounted device defined in claim 2 further comprising a battery, wherein the inductive charging coil receives power from the battery.
4. The head-mounted device defined in claim 3 wherein the head strap comprises traces that convey the power from the battery to the inductive charging coil.
5. The head-mounted device defined in claim 4 wherein the battery is mounted in the main housing portion.
6. The head-mounted device defined in claim 5 wherein the head strap comprises a connector coupled to the main housing portion and wherein the connector comprises contacts that convey the power from the battery to the traces in the head strap.
7. The head-mounted device defined in claim 6 wherein the head strap comprises first and second portions, wherein the traces and the connector are located in the first portion, and wherein the first portion is removable from the second portion and the main housing portion.
8. The head-mounted device defined in claim 1 wherein the head strap comprises a connector configured to mate with a power source that supplies power to the handheld controller and the head-mounted device at the same time.
9. The head-mounted device defined in claim 8 further comprising a battery in the main housing portion, wherein the head strap comprises traces that convey the power from the connector to the battery.
10. The head-mounted device defined in claim 9 wherein the head strap comprises an additional connector coupled to the main housing portion and wherein the additional connector comprises contacts that convey the power from the traces to the battery.
11. The head-mounted device defined in claim 1 wherein the head strap comprises a temple portion and wherein the magnets are located in the temple portion and are configured to hold the elongated shaft at an angle relative to the temple portion.
12. A power source for charging a handheld controller for a head-mounted device, wherein the handheld controller has an elongated shaft extending along a longitudinal axis, the power source comprising:
a housing;
a recess in the housing configured to receive the elongated shaft, wherein the recess is defined by first and second opposing walls that extend along first and second opposing sides of the handheld controller, wherein the elongated shaft is inserted into the recess along a direction that is perpendicular to the longitudinal axis;
magnets in the housing configured to hold and align the elongated shaft within the recess; and
a battery in the housing configured to supply power to the handheld controller while the elongated shaft is received within the recess.
13. The power source defined in claim 12 further comprising an inductive charging coil configured to wirelessly supply the power from the battery to the handheld controller.
14. The power source defined in claim 12 further comprising first contacts in the housing that are configured to couple to second contacts on the handheld controller, wherein the power is supplied to the handheld controller via the first contacts and the second contacts.
15. A charging stick for charging a handheld controller having a battery and an elongated tube-shaped shaft with a first planar surface, the charging stick comprising:
an elongated housing having a rectangular cross-section and a second planar surface configured to mate with the first planar surface of the elongated tube-shaped shaft, wherein the second planar surface forms an outer surface of the charging stick;
an inductive charging coil configured to supply wireless power to the battery; and
a magnet configured to align the inductive charging coil with respect to the elongated tube-shaped shaft.
16. The charging stick defined in claim 15 further comprising a cable configured to supply the power to the inductive charging coil.
17. The charging stick defined in claim 15 wherein the inductive charging coil is one of first and second inductive charging coils in the charging stick, wherein the handheld controller is one of first and second handheld controllers, and wherein the first inductive charging coil is configured to supply power to the first handheld controller and the second inductive charging coil is configured to supply power to the second handheld controller at the same time.
