- 1. User Experience : UI Design Principles Hemant Singh @singhhemant
- 2. Objectives of the presentation Explain “User Experience” Explore Common Design Principles Where to go next? Q&A
- 3. This talk is different No Code Very verbose………… “Use what you know. Do what you’ve always imagined”
- 4. Old Software is well old Old ways of developing applications are passé…….. Limited software tools Design took a backseat Limited hardware support.
- 6. What Changed? •Wide array of devices to consume content •Connectivity everywhere •Touch Computing •Cloud Storage (device store minimum data)
- 7. Change?
- 8. Change?
- 9. Payoffs of adapting new ways Higher Productivity Lower training Fewer errors Adoption of technology by wide spectrum. Satisfied users
- 10. What is User Experience? “It’s the cumulative experience of your product that people remember, talk about, love or hate.”
- 11. Design Principle : Archetypes “Universal patterns of theme and form resulting from innate biases or dispositions”
- 12. Design Principle : Archetypes
- 13. Design Principle : Archetypes
- 14. Design Principle : Fitt’s Law “The time required to move to a target is a function of the target size and distance to the target.”
- 15. Design Principle : Fitt’s Law “Consider strategies that constrain movements when possible to improve performance and reduce error.”
- 16. Design Principle : Fitt’s Law
- 17. Design Principle : Inattentive Blindness “The failure to cognitively process a stimuli that is presented in clear view, leaving the observer without any awareness or memory of the stimulus.”
- 18. Design Principle : Inattentive Blindness • Increased cognitive Load decreases user awareness. • Complex data entry should be broken in simple steps. (Multiple screens, Collapsible areas / Wizards) • Errors on a screen, should be displayed at or near the source of error. • Errors should come quickly enough to be relevant. • Errors should be differentiated from screen text
- 19. Design Principle : Inattentive Blindness
- 21. Design Principle : Pareto’s Principle (80/20) “A high percentage of effects in any large system are caused by a low percentage of variables.”
- 22. Design Principle : Pareto’s Principle (80/20) Non critical functions that are part of the less important 80% should be minimized or removed altogether from the design.
- 23. Design Principle : Pareto’s Principle (80/20)
- 24. Design Principle : Hick’s Law The time it takes to decision increases with the number of alternatives. The law applies to the design of software menus, control displays, context menus and emergency response.
- 25. Design Principle : Hick’s Law
- 26. Design Principle : Five Hat Racks •There are five ways to organize information Location Alphabet Time Category Hierarchy
- 27. Design Principle : Five Hat Racks
- 28. Design Principle : Biophilia “Environments rich in nature views and imagery reduce stress and enhance focus and concentration.”
- 29. Design Principle : Biophilia
- 30. Design Principle : Biophilia •Environments rich in nature views and imagery reduce stress and enhance focus and concentration. •Business applications which deal with learning, healing, healthcare, education, concentration …. should consider biophilia design.
- 31. Design Principle : Rule of Thirds An image should be imagined as divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines, and that important compositional elements should be placed along these lines or their intersection.
- 32. Design Principle : Rule of Thirds
- 33. Design Principle : Savanna Principle Tendency to prefer savanna like environments (Open areas, scattered trees, water, lush grass,..) to other environments.
- 34. Design Principle : Savanna Principle
- 35. Design Principle : Gutenberg Diagram “A diagram that describes the general pattern followed by the eyes when looking at evenly distributed, homogenous information.”
- 36. Design Principle : Gutenberg Diagram
- 37. Design Principle : Gutenberg Diagram
- 38. Design Principle : Symmetry •Elements that are similar are perceived to be more related than elements that are dissimilar.
- 39. Design Principle : Symmetry
- 40. Design Principle : Attractiveness Bias "A tendency to see attractive people as more intelligent competent, moral and sociable than unattractive people." Used in images of people in marketing or advertising.
- 41. Design Principle : Attractiveness Bias
- 42. Design Principle : Horror Vaccui A tendency to favor filing blank spaces with objects and elements over leaving spaces blank or empty.
- 43. Design Principle : Horror Vaccui
- 44. Design Principle : Horror Vaccui
- 45. Design Principle : Contour Bias “A tendency to favor objects with contours over objects with sharp angles or points.”
- 46. Design Principle : Contour Bias
- 47. Design Principle : Garbage In Garbage Out "Quality of system output is dependent on the quality of the system input "
- 48. Design Principle : Garbage In Garbage Out
- 49. Design Principle : Garbage In Garbage Out
