HTML5 based exam tool

This project is about a program that evaluates the capability of the student (user) for detecting and recognizing areas on a picture (in example a mass on a x-ray image). How should it work in a nutshell: 1. The teacher (author) marks areas/ROIs (Region of Interest) on images where a pathology is seen and also define what it is. 2. The user sees the same images and need to define if normal or abnormal. If abnormal the user needs to mark that area and also say what it is. 3. At the end of the session (after going through X number of cases), the user's performance is evaluated by the following: a) did the user label the case correctly as normal or abnormal? b) if labeled as abnormal, did the user mark the same area as the author (gold standard)? c) did the user also name the same pathology as the author (e.g. mass etc.)? This program needs to be HTML5 based and mobile device (e.g. iphone, ipad, android) usable. If you are capable of doing this I can send yo the Statement of Work with a detailed step-by-step description and milestones. Please show me some examples of similar work you have done before. Especially I have to make sure you are experienced in HTML5.
