Cognitive Aspects

According to the Oxford dictionary, cognition is “the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses” (Oxford University Press, n.d.). There are two general modes of cognition are experiential and reflective. Experiential mode is an active state of acquiring information, whereas reflective mode is a state of retrieving that information. Cognition can be broken down into specific processes such as attention, perception, memory, and reasoning (Rogers, Sharp, & Preece, 2012, pp. 66-67). Reflections Cognition allows users to interact with computer systems and learn how to use them effectively. It also allows users to troubleshoot problems. Working in the IT department I take calls from users around the hospital I work at complaining about various problems. I am able to utilize cognition through analysis, reasoning, and problem solving to come up with solutions to the problems. Thoughts Taking cognitive processes into ...

Interaction Types

Interaction types are the ways a person interacts with a product (Rogers, Sharp, & Preece, 2012, p. 46). There are four different types of interactions: instructing, conversing, manipulating, and exploring. Instructing is how users carry out tasks in a system by giving it commands to follow (Rogers, Sharp, & Preece, 2012, p. 47). Reflections I use instructing interactions almost constantly. As an IT analyst for a pharmacy it is my job to maintain pharmacy specific software and data. Right now, I am working on data collection, transferring it from our current health information system to excel spreadsheets to be uploaded into our new information system. As I use Microsoft Excel I often add rules to highlight certain cells only if I have edited the data in them so other users can see what needs to be updated. Adding such a rule is instructing the program to perform a task based on conditions. Utilizing this allows me to highlight data without having to do it manually. Thoug...

Prototype Thoughts

“A prototype is one manifestation of a design that allows stakeholders to interact with it an explore its suitability; it is limited in that a prototype will usually emphasize one set of product characteristics and de-emphasize others. When you hear the term prototype, you may imagine something like a scale model of a building or a bridge, or maybe a piece of software that crashes every few minutes. But a prototype can also be a paper-based outline of a screen or set of screens, an electronic picture, a video simulation of a task, or a three-dimensional paper and cardboard mockup of a whole workstation” (Rogers, Sharp, & Preece, 2012). Reflections A new product can be the most innovative one of its kind, but if the user finds it to be frustrating to use, they will not use it. Allowing potential users to experience the use of product as it is developed allows engineers and designers to develop products that will be both innovative and user friendly. Prototypes are used to help acc...
