Created with Fabric.js 1.4.5 HOW TO ANALYZE A DIGITAL PRODUCT USABILITY ETHNOGRAPHIC Test the quality of users experience in a digital product with an analitic methodology.3 areas: Effectiveness,Efficiency, Satisfaction ANALITICS 1. Inspection * Cognitive walkthroughs (the expert navigates throught the web page to detect errors) * Heuristic evaluation (analysis of the interface based on basic principles) 2. Inquiry * Field observation (interaction of people with web the page) (Qualitive data collection) * Interviews/focus group. (Qualitative data collection) 3. Testing * Thinking aloud (involve participants to understand cognitive process) (Qualitative data collection) Define whether the access to the website is fast, if it is well-organized. The different components such as web browsing, graphics, colors, text, icons are evaluated with a desing methodology. DESIGN 1. Page design: The most visible part of a website, captures the user attention. (Tool: Eye tracking) 2. Content design: The design should facilitate the access to the content. 3. Web design: The structure is never explicitly represented on the screen. The website design is difficult and, often, more important than the page design. Design should work well with small and big fonts and do not include texts inside the images because... -slow download- problem in case of translation.4. Limit the images and the animations: Animations are unidirectional and not hypertextual like the WWW. The animation movement should not repeat indefinitely and multimedia effects should be used only when they increase the user understanding. · Instrumental approach· Multiple tools to proof the usability. · It hides some things · No narrative dimension * Performance measurement (use of tools to test usability measure interaction time to accomplish a task, number of clicks, views...)Quantitative data collection for the performance measurement:WEB ANALYTICS (Measurement, collection, analysis and reporting of internet data for purposes of understanding and optimizing web usage.) - Objective: tracking/analyzing user navigation. Use of Tools as: Other quantitative Tools: · Alexa · DIGITAL HUMANITIES Compare the use of · SimilarWeb concepts, hidden patterns, styles · Google Analytics · BIG DATA Prediction, patterns and correlations. - Users just take a quick look, we must select the most interesting words, phrases and paragraphs,skipping the less interesting parts.- The web should reflect the vision of the users (user-centred design) and the webpage could have more visits in the future. - Legibility > Avoid the use of new technologies: We cant introduce latest versions of HTML, plug-ins, new formats, etc. at the first time that they appear. Wait one or two years after their official introduction (as a final version, not just beta). - Information architecture and links > Use of a specific structure. Study of the behavior of a group of people over a period of time through data collection. 1. Interview Interviewing, when considered as a method for conducting qualitative research, is a technique used to understand the experiences of others. 2.

Genealogical method Genealogy plays a crucial role in the structure of non- industrial societies, determining both social relations and group relationship to the past. 4. Focus group Form of qualitative research in which a group of people are asked about their perceptions and opinions. (Qualitative data collection) Explore direct interaction of people on the web - Easier reach to difficult groups - Easy to explore sensitive issues - Economic Research - Comfort interviewed answering - Data stays recorded - We miss nonverbal communication, lost orality - Confidentiality and privacy reduced - Reduced Anonymity- Ethics of research- Interpretative Flexibility- Asynchronic communication - De-territorialisation (ethnographer is not present) SEMIOTICS CONTENTS This analysis method concentrates in the study of signs and symbols and their meanings in society. (In this case, related to the semiotic used in a webpage) 1. Semantics Sings and their meaning 2. Syntactic Structure of signs 3. Pragmatics Relation between signs and sign-users. This analysis method tries to analyze if the content of the web is accord to his públic 1. Create a content inventory. 2. Make a comparative between our contents and our competences. 3. Study of the contents - Multimedia: loading time, size, placement, etc. - Written contents: key words, headings and structure, impact. 4. Search for the contents which are more attractive to visitors.
