Interactive Systems Design and Evaluation 2Interactive Systems Design and EvaluationUsability is understood as the quality of an end-user’s experience when interacting with a given device or system. Usability is generally about efficiency, effectiveness, as well as the user’s overall satisfaction (Martin-Gonzalez, Chi-Poot, & Uc-Cetina 2016, p. 628). Usability evaluation is focused on how well the end-users of a particular system or device could learn and utilize the product to attain their goals. It is also how contented users are withthat process (Ma, Cao & Gu 2016, p. 578). This report provides a detailed usability evaluation of one specific interactive device. The device that is evaluated is described, along with the method of evaluation used, the usability and task goals, the users who took part in the study, as well as the evaluation ‘capture’ collection method. Device being evaluatedThe device that is evaluated is a multi-touch tablet computer, which is a mobile device. Specifically, it is Toshiba Excite Write 10.1” 32 GB Silver tablet. This product combines a beautiful high-resolution display and a powerful processor to keep the user entertained, inspired and productive. In addition, the user could use the TruPen to draw and write on the screen of this tablet, just as he or she would do with paper and pen (Best Buy 2017). The study will focus on the evaluating this product by grownups with Down syndromefor workplace-related tasks. Evaluation methodThere are several usability evaluation strategies including usability testing, usability inspection, and usability inquiry (Tsals 2017, p. 1803). The chosen evaluation method is usability inquiry. One form of inquiry is with the use of a questionnaire (Kaikkonen et al. 2009, p. 6). In this study, a structured questionnaire would be designed and distributed to the

The structured questionnaire consists of a specific, predetermined agenda with particular questions that are aimed at guiding and directing the process of data collection (Brokaw, Eckel & Brewer 2015, p. 143). The questionnaire will have a total of 9 questions that can be completed with a period of about 15 minutes. It is of note that inquiry is a form of summativeusability evaluation strategy in which the evaluation is done on a complete or almost-complete design under realistic conditions which could be utilized in determining whether or not the design of the product actually meets particular measurable performance and satisfaction goals. Summative evaluation strategy is also done in order to make comparisons, or to determine a usability benchmark (Hornbæk 2010, p. 98). Summative usability evaluation strategy is different from a formative evaluation which is often utilized in finding and eliminating problems during the product’s design and development process, instead of judging a finished product against particular goals (Duh, Tan & Chen 2010, p. 14). Using the questionnaire evaluation method, the evaluation would seek to establish the following: i.Subjective satisfaction: if the end-users like using the device. The evaluation will seekto establish whether the users have positive attitudes towards using the mobile device.Satisfaction, according to Scriven (2012, p. 6), is an important success factor for any system or device with discretionary use.ii.Intuitive design: an almost effortless understanding of the navigation and architecture of the mobile device.iii.Efficiency of use of the mobile device: How speedy experienced users could accomplish tasks with the tablet (Zhang & Adipat 2005, p. 294).iv.Ease of learning: how quickly users who have never seen or used the user interface of the mobile device before could accomplish basic tasks.
