Intended Interaction: Objects Identifier system for blind users
(a) Device Name (b) Features © Solved Problems
Input Device(s) Mobile Camera The device must have the built in camera to capture the image of object.
The image of object will be stored in the device for image processing. A blind or visually impaired people find difficulties to recognize different objects by just touching them (unless trained).
This input device will solve their problem in recognizing these objects by capturing the image of the object through the camera of the device.
Output Device(s) Synchronized Speaker A synchronized speaker that speaks out that which objects is this.
The main feature of the speaker is to speak out the object name after recognition of the captured image or video. A blind or visually impaired people find difficulties to recognize different objects by just touching them.
This device will solve their problem by speaking out the name of object by capturing the image.

Goal and Sub-Goals:
Looking at the operators an obvious one to resolve this goal is Update paragraph
Which has the pre-condition ‘required page of the file should be opened and cursor at start of paragraph’.
We therefore have a new sub-goal: move to paragraph.
The pre-condition is ‘cursor anywhere in document’ (which we can meet) but we want the second paragraph so must initially be in the first.
We set up a new sub-goal, move to start, with pre-condition ‘cursor anywhere in document’ and result ‘cursor at start of document’.
We can then apply move to paragraph and finally update paragraph. We assume some knowledge here (that the second paragraph is the paragraph after the first one).
