The Idea

• Mobile• Pen instead of keyboard or mouse• Describe why your idea is original • Natural form of input• Accessibility/Sharing

Importance of HCI

• Why HCIUsability, usability, usability!

• Designing usable applicationsMany versions and updates

User Testing

• Friends – college students• HCI Ph.D student

Heuristics

• Visibility of system status – Real time score update

• Match between system and the real world – Use user’s language, design cards like real index cards– Correct = green, incorrect = red

• Consistency and standards – Standard windows format and color, consistent buttons.

• Recognition rather than recall – Users don’t have to type in any commands. All the options are

visible. • Flexibility and efficiency of use

– Can be used for any subject (languages, math, science, music, etc).

• Aesthetic and minimalist design – Avoid clutter. Fewest buttons. Big panels.
