The problem I've seen with LCD glasses is that they are still too heavy.&nbsp; I'm sure those of us that wear glasses can attest to the difference a lighter pair of glasses can make when you were them for a long time ... now imagine a set of LCD glasses that 3-4x heavier than the heaviest glasses you've ever worn.&nbsp; I would get uncomfortable eventually.<br /><br />BTW, You can get 640by 480 LCD glasses now.&nbsp; I think I saw an add for some in one of those airline magazines last time I was on a flight.&nbsp; I'm thinking that ad was around $250-300...<br /><br />Josh<br /><br /><br />

They would be ideal for<br />&gt; unobtrusive data representation in mission-critical situations...<br />&gt; ahhh don't we know that language from somewhere? might THAT be<br />&gt; the reason we don't see such devices: because they are *dual use?<br /><br />on second thought, however, I rather believe we WILL see them, but<br />only when we all have bought the clumsier things they have in that<br />pipeline for years to come. and then we will wait a decade for<br />integration of thought-controllability. image that: not even move<br />your arm to turn a page: reader's coma.<br /><br /><br />ralf<br />_______________________________________________<br />gutvol-d mailing list<br />gutvol-d@lists.pglaf.org<br />http://lists.pglaf.org/mailman/listinfo/gutvol-d<br /></blockquote>
