Selfie stick 1, what's the difference between the second generation and the third generation?

The selfie stick is a selfie artifact that is popular all over the world. From 20cm to 120cm, it can be expanded and contracted at will. The user only needs to fix the mobile phone or stupid camera on the telescopic pole, and can take selfies from multiple angles through the remote control.

The origin of the selfie stick is very early, long before the mobile phone has a camera.

Origin one

The first selfie stick was invented by Hiroshi Ueda and Mima Yujiro, and was named "Telescopic Expander Supported by Pocket Camera" [1].

Origin ii

In 1988, Donald N. Horn and Bern Levy filed a patent application for a portable camera/display support rod. This patent describes a long pole of a portable camera, which can shoot from above, and the director can see the picture on the lower display.

Origin three

In 2005, the Canadian inventor Fromm invented a device that can support a camera and applied for a patent (U.S. Patent # 7,684,694). Wayne G. Fromm submitted the device and usage of supporting cameras in 2005.

Origin four

In other words, the selfie stick originated from the extreme sports circle.
