OATS_201601 Injected Errors Study 2

Older Adults Text-entry Studies (OATS): Our goal was to capture participants’ typing behaviour during input in a lab setting and determine the efficiency of the highlighting keyboard error support mechanism. In this experiment we introduced a new type of experiment, designed to overcome the problem of participants typing in very carefully (i.e. the “injected error” algorithm). This time the algorithm was modified to overcome some limitations encountered in a previous experiment (2015-04). The experiment involved only younger users. Study date January 2016 Contents Data and Analysis keyboard_data.sql: data captured from the keyboard *note* due to corruption, some data on older users is missing subjective: subjective feedback data from users tees_data.sql: data captured from the TEES application tees_questions.sql: phrase sets used during the TEES application Study materials exit questionnaire: issued to participants at the end of the session nasa: NASA-TLX and subjective feedback questionnaires given after each condition study plan: aims and process of the experiment sessions task order: participant and task order details for participants injection algorithm: a detailed description of how the injected algorithm works
