1.why do you want to use flowchart in your mobile interface design and screen interface design?
2.how will it help your users to meet the interactive goals?
1.in my opinion, the designer use this method because the flow chart are easy to deliver message to the users by using the graphical thing to make more easier and understand.these flow charts are easy to present the information, ideas, process, and also these flowcharts can help us to preform risk-free experiments that would involve money, emotional, and many more. that's why these flow charts have to use in our mobile interface design and screen interface design.
2. well, for me all designers are responsible to deliver the message to users like documents, process and so on. when the users read and see the flow charts they will understand about the information from the flowcharts thats more simple, easy to read.
