Design a real-time data visualization experience
Athletes and fitness enthusiasts who are serious about improving often have complex workout routines and need to keep track of their progress. This means memorizing everything or carrying around a notebook and pencil, cellphone, tablet, or other device. Pair this with a handheld stopwatch or wrist watch and an iPod with headphones and you’re left with distractions that impair the quality of a workout.
Sketches
My sketches helped visualize where on the arm the tattoo would be best located for easy interaction and visibility. I also explored some gestured-based controls for hands-free interaction.
Research
- 1sp (skin pixel) = 0.25mm = 0.94px = 0.71pt
- Smallest average forearm size: 220 x 70mm = 880 x 280sp
- Thinnest tattoo needle: #6 needle at 0.20mm = 0.8sp
- Minimum line weight: 0.25mm = 1sp
- Minimum type size: 3.53mm = 10pt = 14sp
- Touch target size: 7-10mm = 28-40sp
- Information zones: Least important to most important
- Responsive mode: Horizontal to vertical, inside to outside
- Alternate display: Outside wrist, hand
- Alternate interactions: Gesture based
- Skin color: All supported
