Handwritten work report recognition

Photograph handwritten work reports on the shop floor, and multimodal AI turns them into work records, so nobody has to type them in. A granted invention patent, with me as first inventor.

Background

Many workshops still record output on paper job cards. A worker fills one in by hand, and then someone has to enter it into the system again.

How it works

  1. Take a photo of the handwritten card on the shop floor with a phone;
  2. a multimodal AI reads it and creates the work report;
  3. a second model checks the result and gives a confidence level, and anything it isn’t sure about goes to a person;
  4. mistakes can be corrected by voice.

The approach was filed as an invention patent and has been granted, with me as first inventor.
