Problems of the printing manual

  Conventional printing manuals make the following difficulties.

1. Necessary to change worker's view point between a manual and object frequently.
     Because it is difficult to remember all the contents of the manuals, the worker must carry the manuals and refer them by transferring his/her eyes alternately with the manual and object. However, this dull referencing must causes the next two problems regarding the progress of the work process.
   1. Mistake of the duplication/omission of the work process
        As the most industrial manuals are simple and it is not fun to understand its contents, the worker tends to stop understanding what process of the manual at present work is going on by the frequent view point change between the manual and object.

   2. Complicated branching of the work process depending on the inspection results.
        It often exist to omit and also add some part of work process depending on the measuring results in the adjustment of the electronic part. Such time, the worker needs to read skipped pages of the manual and also needs to return the current page. The condition branching of this work process may cause human errors.
2. Difficulty of finding target object.
     Commonly instructions in printed manuals are written in natural language sentences. Even if photographs or illustrations appear on the manuals, the worker needs to find out the real target corresponding to the graphical materials, it is dull thing for him/her.
