  1. MUSICBLOX Flash Prototype Presentation

  2. MUSICBLOX TEAM MEMBERS • Anika Talapatra • Mayank Mehta • Nicolas Gaumond • Zeid Al-Hammami

  3. MUSICBLOX • A music creation toy. • Children ages 5 and up. • Designed to allow children to be creative, without requiring any instrumental aptitude. • MusicBlox is a direct mapping from composition using notes, to composition using blocks. • Explore the process of music composition, learning the sounds in relation to one another and harmonies between notes.

  4. MUSICBLOX USERS Assumptions about users: • Ability to distinguish between colors. • Ability to memorize/associate notes to colors. • Basic motor and listening skills. • Basic comprehension of picture labels. • Creative capability and musical motivation!

  5. PHYSICAL DESIGN NOTEBLOX • 8 colors, 8 notes • Connect using affordances on sides of the blocks • Note name, and staff position

  6. PHYSICAL DESIGN MAINBLOX • Instrument selection toggle button with default setting • Choose guitar, flute, or piano • Play/stop rocker button

  7. USAGE SCENARIO • Link several noteBlox • Link noteBlox chain to the mainBlox • Select instrument • Press play/stop • Remove mainBlox and demo composition to parents

  8. USAGE SCENARIO • NoteBlox lights up as they play! • Identify and replace ‘wrong’ notes.

  9. EVOLUTION OF THE INTERFACE • Iterative design method • Empirical results from Evaluation Plan at each stage • User-driven changes

  10. OVERALL EVALUATION CRITERIA ·  Intuitive connection of noteBlox. · No more than four task-oriented instruction diagrams. ·  Less than five seconds to add each noteBlox; focus on goal, the musical piece. · Easy identification/change of notes within a string of noteBlox. · Natural memorization of different tones using different colors of the noteBlox.

  11. EVOLUTION: STAGE 1PAPER PROTOTYPE • Basic concept formation • Remove idea of chords and multiple note lengths • Remove baseBlox • Simplifies design for feasibility

  12. I – QUANTITATIVE MEASUREMENT Intuitiveness of interface: Time to assemble/play first song Learnability: Time to assemble/play second song Number of mistakes to correct use II – COGNITIVE WALKTHROUGH How does the interface support each step of usage? NoteBlox colors and side affordances Labels on mainBlox Note lights as it plays EVOLUTION: STAGE 2EVALUATION PLAN

  13. EVOLUTION: STAGE 2EVALUATION PLAN • III – HEURISTIC CRITERIA • Visibility of system status • User control and freedom • Error prevention • Aesthetic and minimalist design • Help users recognize, diagnose and recover from errors

  14. EVOLUTION: STAGE 2 SOFTWARE PROTOTYPE CHANGES 1. Default instrument: Satisfies error prevention 2. Play/stop rocker: Satisfies visibility of system status Overall criteria satisfied

  15. EVOLUTION: STAGE 3ALPHA PROTOTYPE CHANGES • Drawings showing instruments for toggle selection button: Satisfies Visibility of system status • More detailed user diagram: Satisfies Error prevention and recovery • Internalize LED’s: Satisfies Aesthetic and minimalist design, safer for children

  16. EVOLUTION: STAGE 3ALPHA PROTOTYPE POSITIVE USER RESPONSES • Physical affordances were clear • Staff markings provide good mapping • Familiar/“intuitive” language used • Buttons clear to use and indicate state • Visually appealing bright colors

  17. EVOLUTION: STAGE 4BETA PROTOTYPE
