CHAPTER 13 SUMMARY Chapter 13's goals were to identify and distinguish effective electronic communication.
This chapter dealt w/ different aspects of design and multimedia of online electronic communication. (i.e. websites and electronic resources) The chapter analyzed web page design, described the iterative design process, and explained key aspects of information architecture.
Designers and users both see electronic communication as interactive and non linear, virtual and open, complex and dynamic. People access electronic information services through the internet, online with a PC and a variety of types of software. People use handheld PDA's store adresses, browse headlines, and keep calendars.
Accessibility depends on a users memory, bandwidth, and connectivity. Designers must account for differences in screen size for handheld and wireless devices.
The world wide web is comprised of networks of servers and users computers that exchange resources using internet protocols. Sophisticated interactive environments require the server to share resources with the client the same way designers interact with users. Users can access websites through their URL (Uniform Resource Locator) Design components and elements to consider are
screen/page size: How much text can a reader see at one time? Larger screens see more. reading on a monitor reduces the users spacial awareness of the document.
legibility: How easy is it to read whats on the screen? Font, background, and text color, also visual cues like underline, boldface, and italics.
responsiveness: How quickly should a system respond to a users reactions? If the response time is 0.1 seconds or less it seems instantaneous to suers, and they will stay focused if the response time is no more than 1 second. Typically people become distracted if the response time is longer than 10 seconds.
navigation: How easily can people navigate a website? How easily can readers move through and locate places on the text? Web users are influenced by colors, links, backgrounds, images, and icons, even with navigation aids getting lost is easier electronically than on paper.
equipment and services: How much are readers constrained by phisical realities? Even though fast modems and higher bandwidths are available the modems and lines used by most people are too slow for decent response times.
Consider empowerment of the author through empowerment of the reader. Consideration of link sequences and navigation aids is imporant. Links should have additional links that refine the directions purpose and offer multiple equally productive paths based on the users needs.
Some principals and practices of effective design include information architecture (The framework and structure of the content), page/screen designs, and content. The importance of information architecture is to organize the information. A
site map is like a blueprint of a construction site. It expresses the layout and the design of the entire site and internal relationships. The site map categorizes information available to users. The relationships between categories of information are then established. Pathways to information are created based on judgements and user testing. Points of interaction are established this is why functions and forms are included.
A few generic organization schemes are
Heirarchal structure: The main menu provides access to sections and then sub-sections like a pyramid scheme.
Sequential structure: Sequential structure designers exert more control over paths users can take in a prescribed order. (i.e. take a follow through instructional guide pg.1 -> pg.2 -> pg.3
Interlinked structure: Creates multiple relationships on many pages and allows increased flexibility.
Structure on demand: Structures contain static elements and custom responses to users inputs. Here the designer/user interaction is
incredibly complex and the site forms a response to a user
query or input.
The last point of the chapter is the importance of labeling information. Labeling information is essential, and it must be in a way that best allows users to find the resources they need. Labels include page titles, menu items, links, headings, buttons, and controls.
