Week18 : Applications and implications

Final project

Protolight lets you literally “touch” the light in housings by bypassing ordinary light switch.

What will it do?

Specific functions

• Indicator (projected 5x5 pixel image) appears when users get close.

• Sense user interaction with ToF range sensor and sonar sensor.

• Distributes light (total 18W)

• Automatically calibrates focal length when projecting indicator

Who’s done what beforehand?

In terms of “interactive light for living” this is the most similar project I found.

There are some projects tackling to make various kinds of projectors.

Other light related interesting projects (not necessary relevant to my final project)

http://fab.cba.mit.edu/classes/863.13/people/Hasier/Week14.html

What will you design?

• Enclosure

• Electronic PCB boards and, layout and placement of components

• Mechanism for self calibration movement (rack and pinion)

• Light - human interface

What materials and components will be used?

Where will they come from?

How much will they cost?

• Refer to BOM(bill of materials) at the bottom of this page

What parts and systems will be made?

• Enclosure

• LED board : consists of power LED and its driving module, and 5x5 LED matrix

• Controller board : Satshakit

• Self calibration system : works with ToF range sensor and the slider to actuate LED board with in the fitting.

What processes will be used?

• Enclosure : outer frames will be laser cutted MDF, fittings for fixing frames will be 3D

• Circuit boards : PCB design (Eagle) / milling(SRM) / soldering

• Gears and most of the fittings for fixing parts will be 3D printed

• 3DCAD (Fusion360) is used to design whole stuff

What questions need to be answered?

• How can I use light itself to make better interaction for house lightings and users.
  How should indicator look like on 5x5 led matrix? /
  What are the action could be used to interact with light?

• How can I actuate LED board smoothly within the enclosure.

• How can I fix it to lighting duct rail.

• How I use sensors to continuously adjust focal length.

How will it be evaluated?

Whether it addresses to following “light switch issues”:

• Mapping issue (the confusion on which switch corresponds to which light fixture)

• Accessibility issue (how fast can you turn on your desired light)

• Discoverability issue (how easy is it to find out and understand the usage of space)

Test with a person who has never been in our lab before.
