TGC Slides

Jeremiah and I gave a talk at TGC titled Practical Triangle Tessellation last week. I’m still hoping to sit down and record audio here in the office to put online. However, I have put the slides up at this link. Embedding is being a pain, so I haven’t sorted that out yet.



Decreased Postural Stability

Posted in Uncategorized on April 15, 2010 by Dan Amerson

It just never ends. I’m on the record that I don’t think 3D is a particularly good idea. I’ve previously remarked about the goofy glasses. Imagine my lack of surprise when I saw over on CNN that Samsung had issued this warning:

  • Viewing 3D television may also cause motion sickness, perceptual after effects, disorientation, eye strain and decreased postural stability.  It is recommended that users take frequent breaks to lessen the potential of these effects. If your eyes show signs of fatigue or dryness or if you have any of the above symptoms, immediately discontinue use of this device and do not resume using it for at least thirty minutes after the symptoms have subsided.

You can find the full PDF here.

My favorite is “decreased postural stability” a.k.a. you will lose some of your sense of balance. It’s not a lie. I had the same reaction at NVISION a few years ago after playing an FPS for about 15 minutes. I tried to step onto an escalator and almost missed. Seriously, this isn’t a place where we can trick the brain safely. It’s a neat effect to see once a year in a cool movie, but you don’t want it on a daily basis in your house.

Not surprisingly, the PDF also recommends not putting said TV near stairs. dba
