Comments on: DSI - Diffused Surface Illumination http://iad.projects.zhdk.ch/multitouch/?p=90 Wed, 08 Sep 2010 01:37:44 +0000 http://wordpress.org/?v=2.7 hourly 1 By: Nick Clarke http://iad.projects.zhdk.ch/multitouch/?p=90&cpage=1#comment-1325 Nick Clarke Fri, 13 Jun 2008 14:22:28 +0000 http://iad.projects.zhdk.ch/multitouch/?p=90#comment-1325 This is what I was thinking: Frost/Film on the glass Glass -A Gap- Endlighten This way the projected image would hit the frost which is directly under your finger. You could be right with the touch sensation of the material as I guess glass or plexi could feel quite odd. Not felt any frosting yet Was Endlighten what you used in your previous examples you blogged about? as the light does look very even. Home: Vista, Firefox 2.0.0.14 Work: XP Sp2, Firefox 2.0.0.14 At home I don’t have QuickTime but at work I do (I get a upgrade popup). Wonder if it could it be a verion thing. This is what I was thinking:

Frost/Film on the glass
Glass
-A Gap-
Endlighten

I put the projection material directly onto the plexi, so you touch the projection surface with your fingers. Putting the projection material under the plexi does not work, becuase then the IR Light does not get diffused properly. Putting a sheet of glass or transparent "normal" plexi over the projection surface works... but I prefer touching the projection material, just feels better:) The XXL just includes more of those deflecting thingies, not sure how this effects the image... What firefoy are you using and what OS? Works fine on my mac (safari/Firefox)..

I check out the Endlighten product website and it looks quite promising. At the bottom of page 5 (English pdf) it mentions that there should be a gap in between the Plexiglas and the motif (image/picture). I guess you could remove the need for the tracing paper and use some frosted glass which would act as protection (not touching the Endlighten directly) and projection screen. As the glass would not be flexible the gap would remain constant. It’s a shame that it does not appear to be possible to send the IR one way without stopping camera from seeing the blobs. Would the XXL version make any difference or would that just reflect more light? Your site dies when viewed in Firefox, don’t think it likes the QuickTime plug in :) Great write up as usual.
