Since Matt started quoting Alan Kay I feel free to continue. ;) The distinction Alan draws here is between hard fun and soft fun. Soft fun is enjoyable, but you aren't challenged at all. Hard fun pushes you beyond your boundaries and makes you think/learn/work. Smalltalk was all about hard fun. >Alan Kay said that point of view was worth 80 IQ points. >Some have proposed an inverse law for VR: > >The IQ Law of VR: > An HMD will cut the wearer's IQ either by half or by 80 points, >whichever is greater. Don't forget Pausch's IQ Law of VR: An HMD lowers the wearer's IQ by 80 points, which for some people in my research group takes them below zero. Any way Randy can screw up a quote... > How many times have you seen this converstation? > > HMD-wearer: "okay, what do I do now?" > VR-researcher: "just point over there.

Another phenomenon similar to this (for those who've played the Lightsaber Game in VR) is when the VR-researcher holds the lightsaber _behind his back_ so that immersed person can't see it while orienting to the space. *sigh* Jeff
