Higher fidelity Prototype
After the UX bootcamp was over, I went home and prepared a higher fidelity prototype using Adobe Illustrator, Sketch, Material Design, and InVision. I changed the name of the proposed app from "Colors to Words" to "Eye Assist" after a brainstorming session.
This prototype shows the use-case of trying to discern the rail color on a Denver RTD light rail map. The user clicks "camera," then positions the area of the map that needs discernment in the target crosshair near the bottom of the camera image. The user clicks to select the color in the crosshair and a layer opens with the color name, hex value, RGB value, as well as an option to speak the color name aloud. The user can then choose to either save or discard that snapshot and do another area of the map.
This prototype is an early-stage concept only.
