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.
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!
PHYSICAL DESIGN
NOTEBLOXNOTEBLOX 8 colors, 8 notes Connect using
affordances on sides of the blocks
Note name, and staff position
PHYSICAL DESIGN
MAINBLOX Instrument selection
toggle button with default setting
Choose guitar, flute, or piano
Play/stop rocker button
USAGE SCENARIO
Link several noteBlox Link noteBlox chain to
the mainBlox Select instrument Press play/stop Remove mainBlox
and demo composition to parents
USAGE SCENARIO
NoteBlox lights up as they play!
Identify and replace ‘wrong’ notes.
EVOLUTION OF THE INTERFACE
Iterative design method Empirical results from Evaluation Plan at
each stage User-driven changes
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.
EVOLUTION: STAGE 1PAPER PROTOTYPE
Basic concept formation Remove idea of chords
and multiple note lengths
Remove baseBlox Simplifies design for
feasibility
EVOLUTION: STAGE 2EVALUATION PLAN
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
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
EVOLUTION: STAGE 2 SOFTWARE PROTOTYPE
CHANGES
1. Default instrument: Satisfies error prevention
2. Play/stop rocker: Satisfies visibility of system status
Overall criteria satisfied
damn.exe
EVOLUTION: STAGE 3ALPHA PROTOTYPE
CHANGES1. Drawings showing instruments for toggle
selection button: Satisfies Visibility of system status
2. More detailed user diagram: Satisfies Error prevention and recovery
3. Internalize LED’s: Satisfies Aesthetic and minimalist design, safer for children
EVOLUTION: STAGE 3ALPHA PROTOTYPE
POSITIVE USER RESPONSES
1. Physical affordances were clear
2. Staff markings provide good mapping
3. Familiar/“intuitive” language used
4. Buttons clear to use and indicate state
5. Visually appealing bright colors
