I don't think you two have looked at the video that the original post linked to. This is a truly innovative way to achieve the effect, although it might also be innapropriate for children's visual systems.

They have already started doing something that they did with their previous 3-D failure, the mid-1990s Virtual Boy. They have begun advising parents NOT to allow children under 6 years old to play the system because of vague-and-unspecified possible damage to developing visual systems. Both the new system and the older Virtual Boy work in a similar fashion. They are binocular stereogram systems. The Virtual Boy worked like an old Viewmaster, presenting different images to each eye simultanously. The new system has an adjustable masking screen in front of the game screen such that alternating columns of the game screen will be presented to only the left or right eye *if and only if* [IFF] you hold the device at the right distance and don't change that distance from the eyes. This will require a rigid viewing stance. How rigid? How uncomfortable? That remains to be seen. The old Virtual Boy and the new DS 3-D provide a slider switch to adjust for inter-pupil differences. My guess on the scare language is that pretesting has shown that under-6-years-old kids won't hold the device in a steady location and the 3-D effect for them is very intermittent and unsatisfactory. One problem with the old Virtual Boy was that they used only red LEDs to produce images (because blue and green LEDs were very pricy at that point). The consequence was eye strain and opponent-color after images. Ken --------------------------------------------------------------- Kenneth M.
