Abstract: The embodiments of the present invention provide a method and an electronic apparatus for realizing virtual handwriting input. The method for realizing virtual handwriting input includes: obtaining, by an electronic apparatus, position coordinates of a handwriting apparatus in a virtual handwriting area through monitoring in a real-time manner, where the virtual handwriting area is an area in which a distance-measuring detector in the electronic apparatus may perform effective distance measurement; obtaining a track formed by the position coordinates, and obtaining a handwriting track of an entire handwriting input process when it is detected that the current handwriting input ends; and identifying a character corresponding to the obtained handwriting track and displaying the identified character. With the embodiments of the present invention, handwriting input may be realized simply and conveniently, and handwriting input may be realized and may be implemented with a low cost.
