走心走心!!最近對事務所的所有GMAT、UiPath好著迷。

Input methods: robot take some direct actions on automating. 

Make application do something (Ex. Clicks, Text typing, Keyboard shortcuts等)

• Default: works every time 缺點speed(和人類的操作相同)
• Window Messages: 最後才試這個, slowest + lower case
• Simulate Type/Click: 先用這個,fastest; 無法使用keyboard text

Output methods: get info out of the app into UIPath, not recoradable.

Screen scraping: extracting text from running apps, even if they are hidden or covered by another app. (https://www.uipath.com/kb-articles/how-to-use-screen-scraping-the-basics)

• FullText: Fast, accurate, work in the background. 可以隱藏hidden text.
• Native: extract word
• OCR: not 100%, 最後方案。圖像辨識所以部會那麼準

註：

• MS Office專門給larger Images. 
• Google Engines給比較小的. 
• Invert option: black and white.

Web Scraping: scrape structure data(info that follow certain pattern).

The main advantage of the OCR method is:

It’s fast.
It works on every application even if it’s running in a virtual environment.
It works even if the application is running in the background.
