Deb, Here are some to add to your list, they are specific examples, but you can adapt regional/species information to fit your exhibit topic: Fiber optic map (of the Chesapeake Bay) which shows the development and travels of the blue crab from it's early stages through adulthood. The fiber optics on the map are synchronized to back-lit transparencies with pictures of the various stages of development. The centerpiece of the exhibit is an aquarium with live blue crabs. (Virginia Marine Science Museum - permanent exhibit) Fully-articulated, exercise bicycle powered shark and dolphin tails. To operate this exhibit, the visitor actually rides a modified exer-cycle. The pedal/chain drive was modified to operate cables which moved a tail. One bike for the shark, the other for the dolphin. The purpose was to illustrate how the shark tail moves side-to-side and the dolphin tail moves up and down. Ancillary graphic panels explain that since the dolphin is a mammal, it's tail evolved to make it easier for it to surface for air... (Virginia Marine Science Museum - Dolphins, temporary exhibit) A story telling booth with narrations of various local folklore operated by push-button. The tales are narrated "in-character" and sound effects are used to draw visitors into the story. (Jockey's Ridge Visitors Center - permanent exhibit, under development) An exhibit on sportfishing where a touch-screen computer is interfaced to a scale which, among other things, displays the visitors weight in fish. ex. If the visitor is viewing information on red drum, they would see a display which compares their weight to the fish by displaying the number of red drum that add up to their weight. If they weight 100lbs. and a red drum weighs 10lbs., then they would see a scale with 10 red drum on it. (project proposal) Decoy painting, on a touch-screen computer. Visitors can select one of 5 decoy templates and they can paint the decoy with their finger. Various palettes, brushes and pencils are offered in this simplified version of a standard paint program. A retail/home version of this program was also developed which allows saving and printing of decoy masterpieces. The retail/home version also allows the museum to generate revenue from the exhibit. (Atlantic Wildfowl Heritage Museum - permanent exhibit) Tower camera system which allows visitors to view ships in the shipping lane. The current camera angle is shown on a map overlay of the Chesapeake Bay/Atlantic Ocean. A touch-screen computer allows simplified control of the camera directional, zoom and iris controls, and presents the visitors with icons of ship silhouettes. The visitor can select an icon which resembles the ship viewed via camera video (which is presented on a 27" color monitor). Additional information including a color photograph or video of the ship is presented. (The Old Coast Guard Station - in production, opens July '98) These are just a few examples. I was personally involved in all of these exhibits where my duties were the development and construction of electrical/electronic control systems, power transmission systems, software design, programming, system integration and even narrative services. I would be glad to discuss details of these projects or others on this list, via e-mail or on the Exhibit Technology Discussion Group at www.freyaventures.com I would also be interested in working with your firm to develop and produce interactives and touch-screen computer software for your clients.
