1. Memory is a game where you should find a pair that belongs together There could be physical signs that tells you which two parts are matching like a puzzle or two buttons that fit together The clue could be the same sound or vibration parts that match in weight or parts with the same proportion of two tactilly recognizable materials Maybe you should find an object that smells like the task you re given If there are no visual or tactile symbolic traces you have to memorize in other ways which can be interesting in the perspective of learning This also adds to the magic of the experience Collector means that you can feed the dog with the objects you find and collect them in his stomach The collector can be combined with Memory or Treasure Hunt The fattest dog wins The shapes can be felt through the fabric which can be tactilly interesting and create exciting razzling sounds SNIFF Tangible Toy Sara Johansson www sarades no 15 Tangible Interactions spring 2007 AHO Tutors Timo Arnall and Mosse Sjaastad juoasgbeey V NG 7 I Sharing concept the dog has a memory of what he s been fed and only reacts the first time you feed him with a particular piece You have to share what you find with another dog to get a new reaction Another issue to consider was what structures could be made in the room The set up of the nodes can be controlled of a grown up facilitator in advance to create different difficulty lev

SNIFF Tangible Toy for visually impaired children The aim of the project is to bring something extra into situations of social interaction or physical activation amongst kids with a visual handicap Sniff is a toy dog that gives feedback through sounds and vibrations on tagged objects that comes close to his nose The use can be in daily situations as well as in play either alone together with other kids or together with other Sniffs Brief Playful Rfid Rfid offers the opportunity to have action at a distance batteryless and active objects with memory and the use of natural materials without obvious technology on the surface Background Tambartun Kompetansesenter produce stimulation material for kids with visual impairment for training up the senses I have combined this task with the Playful Rfid brief Social interaction and physical activation are the main guidelines for my project It has been important to encourage playfulness and not to help accomplish a specific task or become an exchange for other senses In the design I have explored sound and tactility as feedback Use The two main situations of use is at gatherings at Tambartun centre together with other blind or poorly sighted kids and in the kids natural environment at home or at kindergarten together with seeing kids The last is the most common and also where it s most important to try to make the worlds collide For interaction on same premises
