We often see tickets which are logged as "What do I do with this?" and a screenshot of an error message. The user has not taken the time to type out the error message, and therefore the AnswerBot (or Knowledge capture app for agents) doesn't respond with the right article from Guide.
Adding image recognition services from Google, Amazon, Microsoft upon ticket creation could extract the error message from the image, and append to the ticket.
Like a form of OCR.
To go one step further. Guide Enterprise, which includes Content Cues, should start recognizing screen shots of the same error message, and clustering to respond with content cues relating to error messages.
To go even further again! I am sure many of Zendesk's customers customers, will have people log tickets with images attached. e.g. "Its broken!!!!!" and attached image of a broken fridge door handle to the ticket. Could image recognition be used to identify the issue, transcribe.
