Connected yo-yo
A yo-yo has at least one sensor configured to measure a parameter related to movement of the yo-yo, a transmitter configured to transmit the measured parameter to the computing device. A server is configured to determine a trick performed with the yo-yo based on the measured parameter, and to communicate the determination to one or more computing devices of different players.
1. A system comprising:
a reference device;
a yo-yo comprising:
two shells connected by an axle; and
a sensor housed in one of the two shells, the first sensor being configured to measure a parameter related to movement of the yo-yo; and
a processor configured to determine a position of the yo-yo relative to the reference device based on signals transmitted between the yo-yo and the reference device, or based on a magnetic field strength between the yo-yo and the reference device,
wherein the reference device is separate and distinct from the yo-yo.
2. The system of claim 1 , wherein the reference device is a wearable device.
3. The system of claim 1 , wherein the reference device is a ring and the processor is configured to determine the position of the yo-yo relative to the ring based on a magnetic field strength of the ring detected at the yo-yo.
4. The system of claim 1 , wherein the reference device is a smart watch and the processor is configured to determine the position of the yo-yo relative to the smart watch based on a power, time of flight, or phase shift of signals transmitted between the yo-yo and the smart watch.
5. The system of claim 1 , wherein the processor is housed in the yo-yo.
6. The system of claim 1 , wherein the processor is housed in the reference device.
7. The system of claim 1 ,
wherein the yo-yo further comprises:
the processor;
a memory; and
a transmitter, and
wherein the processor is further configured to:
collect the measured parameter related to movement of the yo-yo from the sensor while the yo-yo is not in wireless communication with a computing device, and store the collected measured parameter in the memory; and
upon establishing wireless communication with the external computing device, cause the transmitter to transmit the stored measured parameter to the computing device.
8. The system of claim 7 , wherein the reference device is the computing device.
9. The system of claim 7 , wherein the yo-yo, the reference device, and the computing device are separate devices and all in wireless communication with each other.
10. A method comprising:
measuring a parameter related to movement of a yo-yo with a sensor housed in a shell of the yo-yo, the yo-yo comprising to shells connected by an axle; and
determining a position of the yo-yo relative to a reference device by:
determining a power, time of flight, or phase shift of signals transmitted between the yo-yo and the reference device, or
determining a magnetic field strength of the reference device at the yo-yo,
wherein the reference device is separate and distinct from the yo-yo.
11. The method of claim 10 , wherein the reference device is a ring and the position of the yo-yo is determined based on the determined magnetic field strength of the reference device at the yo-yo.
12. The method of claim 10 , wherein the reference device is a smart watch and the position of the yo-yo is determined based on the determined power, time of flight, or phase shift of signals transmitted between the yo-yo and the smart watch.
13. The method of claim 10 , further comprising:
storing the measured parameter in a memory of the yo-yo while the yo-yo is not in wireless communication with a computing device; and
upon establishing wireless communication with the external computing device, transmitting the stored measured parameter to the computing device.
14. The method of claim 13 , wherein the computing device is the reference device.
