"Give me a dollar or I'll spit on you."..Meet Bradley Chalkers. He's the oldest child in the class. He tells ENORMOUS lies. He picks fights with girls. The teachers say he has 'serious behaviour problems'. And no one likes him Except Carla, the new school counsellor. She thinks Bradley is sensitive and generous, and she even enjoys his far-fetched stories. Carla knows that Bradley could change, if only he weren't afraid to try. Sometimes the hardest thing in the world is believing in yourself...A heartwarming story of isolation, bravery and acceptance from the bestselling author of Holes, Louis Sachar.
This monograph originates from my work on the HAPTEX project. In - cember 2004 Prof. Franz-Erich Wolter, the head of the Institute of Man- Machine Communication of the Leibniz Universit. at Hannover, o?ered me the opportunity to participate in that EU funded project. Being a mat- matician I had only very little experience in the ?eld of haptic simulation in those days, but Prof. Wolter trusted in my ability to become acquainted with new ?elds of research in a very short time. I am still thankful for the con?dence he has shown me. Since then I indeed learned and found out a lot. With this monograph I try to pass on the knowledge I gained. Having a reader in mind who-like me at the beginning of the project-has no background in psychophysics, neurophysiologyortextileengineeringIwillprovidethenecessarybasics.The skilled reader may safely skip these parts. Nevertheless I presume some basic knowledge in mathematics. I hope that this thesis might help a newcomer to discover the fascinating ?eld of tactile simulation. This workwouldnot havebeen possible without the funding of the project "HAPtic sensing of virtual TEXtiles" (HAPTEX) under the Sixth Fra- work Programme (FP6) of the European Union (Contract No. IST-6549).
