Global shipments of smartwatches reached nearly 42 million in the first half of 2020, up 20 percent from the same period in 2019, according to the report. However, while users enjoy the convenience of a Smart Watch, there are many problems in the input of the watch, such as small screen, slow input, no EMOJI and other problems need to be solved. In response to this pain point, the Sogou Pinyin recently partnered with artificial intelligence company go out and ask to officially launch a built in custom built version of the SOGOU Pinyin in go out and ask to see the flagship smartwatch TicWatch Pro 3. Small screen input can also be fast and accurate current smartwatches have screens in the range of 0.8 to 1.5 inches.

Sogou Pinyin's answer is to create customized versions for different hardware.
