The document describes two input devices: 1) A tangible articulation device that uses magnets and sensors to accurately control 3D character movements. 2) LightBundle, which uses plant-inspired interactions like grasping, peeling, twisting bundles of light to convey information through properties like location, awareness and energy transfer. Both aim to improve on traditional mouse/keyboard by matching perceptual and control spaces.

1. Tangible and Modular
Input Device for
Character Articulation

2. Introduction
Traditional Skeleton operation with Mouse
and keyboard interfaces fall short because
their control spaces do not match the
perceptual space of the 3D interaction.

3. How it works?
Pairs of permanent magnets and Hall-effect sensors embedded in each joint measure
rotations

4. Control principles
1. Joint
2. Splitter
3. Extension segment
4. Endcap
5. Controller

10. Review
 Reduce the eye hurt.
 Reduce the skeleton Recording time.
 Accurate control to skeleton.

11. LightBundle: Grasping
Light through Plant-
Inspired Interactions

12. Introduction
• Inspired by our daily interactions with bundles
of vegetables
• LightBundle affords grabbing, peeling and
twisting of bundle and strands
• The metaphoric plant properties lend
themselves to interaction scenarios ranging
from timing, location, social awareness to
energy transfer

13. How it work?

14. Bundling
Explore the direct manipulation of the grasping and releasing a bundle

15. Peeling
By peeling open an outer layer an inner layer is revealed

16. Pointing
Take the growth directionality of plants as a metaphor and enable the strands
in the bundle to point in different directions to indicate information

17. Twisting
Use this action of twisting together strands as a metaphor for binding
and connecting two different sources of information

18. Grasping
By grasping light the light in the room dims down

19. Social
In the social aspect, the LightBundle enables one
to keep up to date with what is happening
with their friends without having to spend
countless hours on social networking sites.

20. Pointing
With the pointing metaphor, one can imagine a scenario during a dinner party
where the host wants to keep track of when his guests are arriving .

21. Review
 How plant-inspired metaphors open interaction opportunities in
bundles and strands of optical fibers.
 LightBundle as a Radical Atom that changes color, light, and sensing
properties based on user manipulation.
 In the future where material properties become malleable and
seamlessly engage our full sensory.
