User Interaction in BAS: Handing Control to a Human

Not everything should be fully automated - sometimes the smartest move is to let a human step in for one tricky moment. The User Interaction module is built for exactly that: a controlled hand-off between bot and operator.

What it does

The module lets you pass manual control to a person during an auto-scenario, play sound notifications, request input from the user, and run JavaScript inside web interfaces. It turns a fully automatic bot into a semi-automatic one where a human handles the parts that aren’t worth automating.

The actions

• Play sound - alert the operator that the bot needs attention.
• Request input from the user - pause and ask a person to type a value the bot can’t determine on its own.
• Execute script in the web interface - run JavaScript against the interface.
• Manual control - transfer control of the browser to the person, then take it back.

The classic use: manual captcha

The book’s example is the perfect one. On your first bot you hit a captcha you don’t want to solve through an automated service. Instead of building a solver, you use transfer manual control: the bot pauses, you solve the captcha by hand in the live browser, and then control passes back to the bot, which carries on.

When semi-automatic wins

Full automation has diminishing returns on rare, hard, low-volume steps. If a bot meets one captcha per run, or occasionally needs a human judgement call, the User Interaction module is far cheaper than engineering a fully automatic solution. Reach for it when a step is rare and hard - let the bot do the 95% it’s good at, and tap a human for the awkward 5%.
