Abstract: A computer assisted design system (100) that includes a computer system (102) and text input device (103) that may be provided with text elements from a keyboard (104). A user may also provide oral input (107) to the text input device (103) or to a voice recognition software with in-built artificial intelligence algorithms (110) which can convert spoken language into text elements. The computer system (102) includes an interaction design heuristic engine (116) that acts to understand and translate text and language into a visual form for display to the end user.
