Goals for The New ComputingGoals for The New Computing
1) Usable: Reliable& comprehensible
2) Universal: Diverse users & varied equipment
3) Useful: In harmony with human needs
1) Usable: Ending User Frustration 1) Usable: Ending User Frustration
• Goal - make computer usage less frustrating• Identify top ten frustrations • Measure severity & frequency in lost time• Determine if the situation is improving
• Related areas • Errors• Time delays• Emotional reactions
& testing methods• Web producers: Develop UU statements• Managers: Provide responsible leadership• Journalists: Raise public expectations• Policy makers: Raise & clarify requirements• Funders: Expand research on usability• Educators: Disseminate scientific results • Researchers: Explore bold new visions
