T or F 1 A windowing system will have a fixed generic language which is called T Imaging Model. 2 windowing system are Management of independent but simultaneously active T applications 3 The Java toolkit for developing windowed applications is called the AWT T 4 Toolkits provide Consistency and Generalizability for an interactive T system 5 Toolkits to provide flexibility the interaction objects can be modified T 6 Toolkits To provide flexibility the interaction objects can be modified F 7 Examples of UIMS are Serpent & Picasso T 8 10 Reusability of components reduces development costs T 11 Portability runs on different systems and provides device independent interface T 12 PAC Groups input and output together. T 14 Evaluates both design and implementation T 15 Evaluates Tests usability and functionality of system T 16 Evaluates Should be considered at all stages in the design life cycle T 17 Cognitive Walkthrough Proposed by Polson et al. T 18 expert ‘walks though’ design to identify possible problems using psychological T principles 19 Heuristic Evaluation Proposed by Nielsen and Molich. T 21 Heuristic evaluation `debugs' design. Debugging means identifying errors and T fix them 22 dependent variable (dV) characteristics measured in the experiment e.g. time T taken, number of errors 23 The null hypothesis states no difference between conditions T 24 Within(inside) groups design each subject performs experiment under each T condition 25 Between groups design each subject performs under only one condition T 27 Within(inside) groups design less costly and less likely to suffer from user T variation. 28 Between groups design more users required and variation can bias results. T 29 Analysis of data Choice of statistical technique depends on type of data and T information required 30 Analysis of data Before you start to do any statistics look at data and save T original data 31 parametric assume normal distribution T 32 Non-parametric do not assume normal distribution and less powerful and more T reliable 33 Parametric assume normal distribution and powerful T 34 Likelihood table count number of data items in each group T 35 post-task walkthroughs necessary in cases where think aloud is not possible T 37 logging automatic, large amounts of data difficult to analyze T 38 user notebooks coarse and subjective, useful insights, good for longitudinal T studies  39 video accurate and realistic, needs special equipment computer T 40 audio/video transcription difficult and requires skill. T F 42 scan paths moving straight to a target with a short fixation at the target is T optimal 43 Saccades rapid eye movement from one point of interest to another T 45 physiological measurements these may help determine a user’s reaction to an T interface 46 physiological measurements some difficulty in interpreting these physiological T responses - more research needed Q2. ‫ﻓﺮاﻏﺎت ﺑﺪﻟﮭﺎ ﻣﻤﻜﻦ
