However, end-users and third-party tech support typically cannot create contextual help to assist other users because it requires programming skill and source code access. We present a creation tool for contextual help that allows users to apply common computer skills-taking screenshots and writing simple scripts. We perform pixel analysis on screenshots to make this tool applicable to a wide range of applications and platforms without source code access. We evaluated the tool{\textquoteright}s usability with three groups of participants: developers, in-structors, and tech support. We further validated the applicability of our tool with 60 real tasks supported by the tech support of a university campus.}, keywords = {contextual help, help, pixel analysis}, isbn = {978-1-4503-0716-1}, doi = {10.1145/2047196.2047214}, url = {http://doi.acm.org/10.1145/2047196.2047214}, author = {Tom Yeh and Chang,Tsung-Hsiang and Xie,Bo and Walsh,Greg and Watkins,Ivan and Wongsuphasawat,Krist and Huang,Man and Davis, Larry S. and Bederson, Benjamin B.} }
