In today's society, computers and mobile phones have become information centers that people cannot leave for a moment. However, handwritten records that are constantly generated anytime and anywhere are scattered in paper notebooks and cannot be stored in computers. The mutual isolation of these two information carriers is a huge obstacle to the advancing paperless and cashless life!

A digital pen offers a great solution to this regret. Digital notebooks, digital pens, and mobile phones are the same as ordinary pens, notebooks, and mobile phones that must be carried now, without adding any burden to users, and even the cost is similar. However, the information management of handwriting has been realized, and the simple text record has been upgraded to a text-voice composite record, which can be regarded as an upgrade and breakthrough of traditional handwriting technology.
