Shumin Zhai

Shumin Zhai, a prolific inventor based in Los Altos, CA, has made significant contributions in the field of touch keyboard technology. With an impressive portfolio of 100 patents, Zhai has emerged as a leading figure in the creation of innovative input methods for computing devices.

One of Zhai's notable inventions is the touch keyboard using a trained model. This invention allows a computing device to display a graphical keyboard, detect gestures to select a group of keys, and determine the characteristics associated with these gestures. By modifying a spatial model based on these characteristics, the device can generate candidate words using data from the spatial model and a language model. This technology enables more efficient and accurate text input, enhancing user experience on touch-enabled devices.

Zhai also developed the virtual keyboard error correction based on a dynamic spatial model. This method involves mapping touch inputs on a virtual keyboard to first and second candidate keys using a combination of a spatial model and a language model. The spatial model leverages prior touch inputs by the user, while the language model predicts the next keys based on the touch input's position. By selecting the most suitable key based on these mappings, this invention improves the accuracy of virtual keyboard input and helps users correct errors more effectively.

Throughout his career, Shumin Zhai has worked with esteemed companies such as Google and IBM (International Business Machines Corporation). Collaborating with talented individuals like Yu Ouyang and Xiaojun Bi, Zhai has harnessed the power of technology to push the boundaries of touch keyboard capabilities.

As a trailblazing inventor, Shumin Zhai continues to make significant strides in the field of touch input innovations. His patented technologies have revolutionized the way we interact with computing devices, providing more efficient and intuitive input methods for users worldwide.
