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'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. %B Proceedings of the 24th annual ACM symposium on User interface software and technology %S UIST '11 %I ACM %C New York, NY, USA %P 145 - 154 %8 2011/// %@ 978-1-4503-0716-1 %G eng %U http://doi.acm.org/10.1145/2047196.2047214 %R 10.1145/2047196.2047214
