    • 1. Requirements Definition Of the Geospatial Web
    • 2. Review <ul><li>Last week we looked at different tools and technology used in the geospatial web </li></ul><ul><li>This next phase will look at implementing these tools into the design flow of website </li></ul>
    • 3. What makes a website Good? <ul><li>Intuitive </li></ul><ul><li>Transparent </li></ul><ul><li>Efficient </li></ul><ul><li>Well organized </li></ul><ul><li>Relevant Timely Content </li></ul><ul><li>A website that is good is usable. </li></ul>
    • 4. Usability <ul><li>Can be defined as “the degree to which people can perform a set of required tasks.” - Usability for the Web Brinck et al. (2002) </li></ul><ul><li>A good website is a product of good design and careful consideration of every user interaction and the users expectations at every step in their interaction. </li></ul>
    • 5. Design Goals <ul><li>Functionally correct </li></ul><ul><li>Efficient to Use </li></ul><ul><li>Easy to learn </li></ul><ul><li>Easy to remember </li></ul><ul><li>Error tolerant </li></ul><ul><li>Subjectively pleasing </li></ul>
    • 6. Why is it important? <ul><li>Competition for users </li></ul><ul><li>Increased productivity </li></ul><ul><li>Saving Money </li></ul><ul><li>High usability is a key factor in achieving maximum return on information technology investment. </li></ul>
    • 7. 5 Planes <ul><li>A Highly usable website is a result of careful consideration on many different levels. When peeled away we see layers of this user experience. </li></ul><ul><ul><li>The Surface Plane </li></ul></ul><ul><ul><li>The Skeleton Plane </li></ul></ul><ul><ul><li>The Structure Plane </li></ul></ul><ul><ul><li>The Scope Plane </li></ul></ul><ul><ul><li>The Strategy Plane </li></ul></ul>

    • 9. Duality of Web Design Application Design Information Distribution and Retrieval Human Computer Interaction Information Architecture Interaction Design ? Knowledge Management
    • 10.  
    • 11. Design Tools <ul><li>At each stage of the design process we utilize different tools to help us find the information we need to know. </li></ul>
    • 12. Strategy Plane <ul><li>We are concerned with Defining the Requirements and therefore focus on </li></ul><ul><ul><li>The target Audience </li></ul></ul><ul><ul><li>The Site Goals </li></ul></ul><ul><ul><li>The User Needs </li></ul></ul><ul><ul><li>The Business Goals </li></ul></ul>
    • 13. Requirements Definition <ul><li>This helps us ask several key questions: </li></ul><ul><ul><li>Who are we designing for? </li></ul></ul><ul><ul><li>What is the purpose of the project? </li></ul></ul><ul><ul><li>How will it be useful to our user audience? </li></ul></ul>
    • 14. Tools of Requirements Definition <ul><li>Use Cases </li></ul><ul><li>Personas </li></ul><ul><li>Competitive Analysis </li></ul><ul><li>Defining Business Goals </li></ul>
    • 15. Persona Example
    • 16. A persona usually includes: <ul><li>a name and picture </li></ul><ul><li>Demographics (age, education, ethnicity, family status) </li></ul><ul><li>Job title and major responsibilities </li></ul><ul><li>goals and tasks in relation to your site </li></ul><ul><li>environment (physical, social, technological) </li></ul><ul><li>a quote that sums up what matters most to the persona with relevance for your site </li></ul>
    • 17. Use cases <ul><li>Describe how a particular user will perform a given task on your website </li></ul><ul><li>These are usually narrative in format and define through the story the steps a user must take to perform the task </li></ul><ul><li>Each use case captures </li></ul><ul><ul><li>The Actor (who is using the Website) </li></ul></ul><ul><ul><li>The Interaction (what the user does) </li></ul></ul><ul><ul><li>The Goal (the user’s purpose) </li></ul></ul>
    • 18. The Scope Plane <ul><li>The focus becomes less abstract as we look at the functional specifications </li></ul><ul><ul><li>Technical Specifications </li></ul></ul><ul><ul><li>Content Requirements </li></ul></ul>
    • 19. Tools <ul><li>Often Creative briefs are used in this phase </li></ul><ul><li>This defines the conceptual approach, genres, metaphors, and imagery is to be used. </li></ul><ul><li>Ie. Comic approach - fun or serious </li></ul><ul><li>These are often used for strategy to make something memorable to the user audience. </li></ul>
    • 20. Structure Phase <ul><li>Conceptual design begins as designers begin to determine how information is organized and the system behaves </li></ul><ul><li>Typically this is called Interaction Design and Information Architecture </li></ul>
    • 21. Tools <ul><li>Information architecture is concerned largely with taxonomies </li></ul><ul><li>Interaction design is concerned with User flows </li></ul>
    • 22.  
    • 23.  
    • 24. The Skeleton Plane <ul><li>Elaborates on the information Architecture and Interaction Design through Wireframing </li></ul><ul><li>Wireframing concerns itself with the placement of content pieces without concern for the look </li></ul><ul><li>Can be done in a variety of applications including Photoshop, Visio, Illustrator, OmniGraffle etc </li></ul>
