1 CHI What I Saw… Tutorials Contextual Design: Using Customer Work Models to Drive Systems Design Design and Rapid Evaluation of Usable Web Sites SIGs A "Bag of Tricks" for Web Usability Panels Interactionary: An Interaction Design Competition Scaling for the Masses: Usability Practices of the Web's Most Popular Sites Papers User Experience in E-Commerce 3D Environments Tools for Design

2 CHI Tutorial 1 Subject: Contextual Design: Using Customer Work Models to Drive Systems Design Authors: Hugh Beyer & Karen Holtzblatt InContext Enterprises Summary: Authors presented methodologies and representational models for capturing work practices. Once gathered across user groups, these models can be consolidated in order to drive the (re)design of systems to aid those work practices. Contextual Design

3 CHI Contextual Design Process Contextual Design Beyer, H. and Holtsblatt, K., “Contextual Design: Using Customer Work Models to Drive System Design” in Tutorial notes for CHI 2000, April , the Hague, Netherlands.

4 CHI Contextual Design Process Contextual Design Beyer, H. and Holtsblatt, K., “Contextual Design: Using Customer Work Models to Drive System Design” in Tutorial notes for CHI 2000, April , the Hague, Netherlands.

5 CHI Work Models Flow – the communication and coordination between people and roles performed in service of the intent irrespective of time Sequence – the detailed work steps in time to accomplish a task Cultural – the overall climate and cultural forces present in the environment of the customer Physical – the layout and structure of an individual work space or site showing how it supports the work Artifact – the structure and usage of a work artifact Contextual Design

6 CHI Flow Model Contextual Design Beyer, H. and Holtsblatt, K., “Contextual Design: Using Customer Work Models to Drive System Design” in Tutorial notes for CHI 2000, April , the Hague, Netherlands.

7 CHI Sequence Model Contextual Design time Beyer, H. and Holtsblatt, K., “Contextual Design: Using Customer Work Models to Drive System Design” in Tutorial notes for CHI 2000, April , the Hague, Netherlands.

8 CHI Cultural Model Contextual Design

9 CHI Physical Model Contextual Design Beyer, H. and Holtsblatt, K., “Contextual Design: Using Customer Work Models to Drive System Design” in Tutorial notes for CHI 2000, April , the Hague, Netherlands.

10 CHI Artifact Model Contextual Design Beyer, H. and Holtsblatt, K., “Contextual Design: Using Customer Work Models to Drive System Design” in Tutorial notes for CHI 2000, April , the Hague, Netherlands.

11 CHI Consolidation Once all work models have been gathered, each model is consolidated in order to represent the superset of the work process Reveals common underlying pattern: Intent – the purpose or motive for a task Strategy – a pattern for doing work Structure – an organization of the physical or social environment to support work Concepts – distinctions that help people think about their work and how to do it Mindset – values and identity Incorporates variations Contextual Design

12 CHI Consolidated Flow Contextual Design Beyer, H. and Holtsblatt, K., “Contextual Design: Using Customer Work Models to Drive System Design” in Tutorial notes for CHI 2000, April , the Hague, Netherlands.

13 CHI Redesigning the Work Contextual Design Beyer, H. and Holtsblatt, K., “Contextual Design: Using Customer Work Models to Drive System Design” in Tutorial notes for CHI 2000, April , the Hague, Netherlands.

14 CHI Take-aways Positive Employing Contextual Design methods can be useful in the creation of new tools for the web but primarily within a known audience of users when functionality of site is driven directly around supporting specific tasks Limitations in approach Presented as an end-all for design Must stay objective while collecting data and (re)designing application Time consuming Multiple people (group) needed to properly collect, consolidate and extract models and new work processes Contextual Design

16 CHI Tutorial 2 Subject: Design and Rapid Evaluation of Usable Web Sites Authors: Gene Lynch Design Technologies, Inc. Summary: Presentation was primarily a fast- paced overview of successful, main- stream, user-centered principles to employ during web site. Evaluation of Usable Web Sites

17 CHI Topics Web Site Usability User and web site purpose Web site classification and functionality Design plan, process and issues Card sorts for web site function and structure Scenario-based design User personas Scenarios for design and evaluation Web site design guidelines 4 graphic principles and examples Design principles, heuristics and examples Methods for evaluating web site usability A rapid evaluation process Heuristic reviews Team usability walkthroughs Evaluation of Usable Web Sites

18 CHI Take-aways Positive Incredible amount of reference material and follow up directions for further, more in-depth exploration Good over view of the variety of aspects employed in user centered design and evalution. Session notebook good reference for new employees/internal education. Negative Too much for one day (this was a 2 or 3 day seminar compressed pages of slides within 6hr session!) Geared to the novice web person Crowd often took away from richness of information discovery because of level of understanding of domain (web) (i.e.. Questions out of sync with topic) Evaluation of Usable Web Sites

23 CHI Web Site Usability (references) 7 Debilitating Diseases of Business Web Sites – Dr. Ralph F. Wilson, Web Marketing Today Background Blemish Complex slow and distracting Button Bloat Sites that make you wait while many individual buttons download, rather than a single navigation bar or clickable map Navigation Neuralgia Too many or too few top-level choices. Structures not related to customer needs Evaluation of Usable Web Sites

24 CHI Web Site Usability (references) Top Ten Mistakes in Web Design Jakob Nielsen Frames Over-use of “leading-edge” technology Scrolling text, marquees and animations Complex URLs Orphan pages Long scrolling pages No navigation support Non-standard link colors Outdated information Long download times Evaluation of Usable Web Sites

28 CHI Panel Subject: Scaling for the Masses: Usability Practices of the Web’s Most Popular Sites Organizer:Jared Spool User Interface Engineering Summary: Open round-table of usability professionals from eBay, CNET, Yahoo!, Intuit and Fidelity. Each discussed specific aspects of their site and all answered questions generated by audience. Scaling for the Masses
