Hi, I’m writing from a small market research firm in Bath. We’ve been commissioned by the Open University to conduct market research into the commercial potential for an educational astronomy-related product that’s under development.There's not that much information about it at the moment, although it's an interesting idea if the large-scale versions are anything to go by. I can imagine that it might be a useful prop of you're the sort of person who gives tours of the night sky to groups of people, but I'm struggling to think of a personal use (other than the gadget-value anyway).
The product is called ‘Space Signpost’, and it’s a desktop gadget that will physically turn and point to the exact location of any astronomical body. Here’s a link to the Space Signpost web site, which shows some of the educational prototypes to date; I can also post a sketch of some of the thinking for potential design of the commercial product, which is a much smaller desktop version, with specific features as yet undetermined.
My response to the questions can be found here.
