T-REX is an atmospheric light that can only be turned on by other light sources through the use of human-computer interaction and embodied design techniques. It was developed in two parts - the design used analysis, metaphor definition, and form-making to convey the idea that the light activates like a candle being lit. The engineering part used an Arduino controller and programming to make the light respond to different light intensities and turn off automatically or through clapping. The goal was to create a new lighting experience that activates through light-based interaction rather than switches.

1. T-REX
Light up the light

2. T-REX is a atmosphere light which can only be turned
on by lights, with HCI and embodied design
techniques, we are able to set up the system and run
programs to bring a new and special experience to
household illumination area.
T-RE

3. Introduction
T-REX is a atmosphere light which can only be turned on by lights, with HCI
and embodied design techniques, we are able to set up the system and run
programs to bring a new and special experience to household illumination
area.

4. Concept Building
Several concepts, metaphors and movements had
been tried. And finally we finish the discussion by
clear annotation.

5. Metaphor
“Ignite the deep perception about connections between light and
fire”.
Since human knew how to use fire, the feature of light were connected with heat,
radiation and transitive of energy.
❏ Once we woke up the user’s instinct to operate T-REX, they can follow their
intuition as same as they deal with candles, or other light sources using fire.
❏ Features and pattern can be duplicated on this system with logic and
predictable factors.

6. Annotation
❏ Light will extinguish like candle or fire
❏ Light up T-REX with light source
❏ Enhance the awareness of using light
❏ Increase the interaction by use light to activate light
❏ The light will affect by different lighting qualities

7. Rules
Turn on
light
source
Use light
to
light up
Clapping
hands to
turn off
Auto
Extinguish
The longer user Irradiate,
the brighter T-REX become
The light source should be
bright enough
The light will turned off
in random.
Like candles, the light
will extinguish after a
period of time.

8. Design Approach
T-REX was developed in two main parts,The design part went through analysis,
metaphor definition, function and appearance organization.
The engineer part we use arduino as our intel controller, and program editing
tool. The process mainly were coding, testing and welding.

9. Form Making
How to convey the idea through Form?

11. Laban Movements
Turn on the light: Moving the light source
Time
Sudden Sustained
Space Direct Indirect
Weight Light Strong
Flow Flow Bound

12. Laban Movements
Turn of the light: Clapping hands

13. Model Making
Build up by Rhino, 3D printer and welding

14. Arduino Programming
The engineer part we use arduino as our intel controller, and
program editing tool.

15. Usage Scenario
Reading in the living room

16. Conclusion
Create the spaces in the interaction, there are free
possibilities to let users try their own way lighting up the
light, flash light, another lamp, or a even a real candle.
