Three performance measures were derived for every task on the premise of the written responses and knowledge from the Hypercam screen capture utility. AN accuracy score (A) was computed that was a composite live of the correctness of the written response (C= actual score (X)/maximum score) and therefore the range of correct actions completed (F = actual actions (Y)/correct actions). Correct actions delineated actions the participant required to complete to access the data required to resolve the matter(eg, click on a link) and mirrored the extent to that a participant traversed the web site properly. Task one needed a complete of 5correct written responses (C = X/5) and sixteen actions (F = Y/16), and so A = X/5 + Y/16. Task two needed eight correct written responses (C= X/8) and 6 correct actions (F= Y/6), and so A = X/8 + Y/6. Task three needed eight correct written responses (C = X/8) and twenty two correct actions (F = Y/22) leading to A = X/8 + Y/22.An potency live was outlined because the accuracy score for the task divided by the natural log of your time taken for the task (A/T). A live of navigation was derived by dividing every task into stages and later on computing the degree to that a participant traversed through these stages. Tasks one and a couple of had six stages and task three had seven stages.Coding of the written responses and therefore the video capture knowledge was standardized and target-hunting by secret writingsheets. The secret writing was supported strategies developed in our previous research4 vi and concerned a comprehensive identification of all steps and actions needed for completion of the task. samples of coded things from the screen capture knowledgeincluded: clicking essential buttons and links, coming into data (eg, a zipper code), and viewing webpages.
