Methods for new mobile experiences, from concept creation to prototyping to commercialization.The mobile device is changing the ways we interact with each other and with the world. The mobile experience is distinct from the desktop or laptop experience; mobile apps require a significantly different design philosophy as well as design methods that reflect the unique experience of computing in the world. This book presents an approach to designing mobile media that takes advantage of the Internet-connected, context-aware, and media-sharing capabilities of mobile devices. It introduces tools that can be used at every stage of building a mobile application, from concept creation to commercialization, as well as real-world examples from industry and academia.The methods outlined apply user-centered design processes to mobile devices in a way that makes these methods relevant to the mobile experience—which involves the use of systems in the complex spatial and social world rather than at a desk. The book shows how each project begins with generative research into the practices and desires of a diverse set of potential users, which grounds research and design in the real world. It then describes methods for rapid prototyping, usability evaluation, field testing, and scaling up solutions in order to bring a product to market. Building Mobile Experiences grew out of an MIT course in communicating with mobile technology; it is appropriate for classroom use and as a reference for mobile app designers.
Assembly Instructions for Nucleic Acid Models describes the step-by-step instructions in building a single nucleotide using the Academic Press/Molecular Design Inc. (AP/MDI) models. This booklet also provides instructions for constructing models of the DNA-B (Watson-Crick), DNA-A, and the DNA-Z forms. This text illustrates the chemical composition and atom numbering system of the nucleotide unit, the fundamental building block of all nucleic acids. The framework components include the atomic pieces for phosphorous, oxygen, carbon, nitrogen, and the fused pieces that represent two bases and two furanose rings. Building models of the different nucleic acid structure involves adjustments of seven torsion angles; in the AP/MDI Molecular Model System, only six angles are adjusted. In constructing larger DNA structures, the operator assembles a series of nucleotide units. He should also be familiar with the seven torsion angles of these structures which are composed of six adjustable angles and the correct ring conformation. This guide also contains a table listing the torsion angles for several forms of DNA. This booklet is suitable for students in chemistry, new chemist practioners, professors in chemistry, as well as other researchers whose works involve some chemical investigations and experiments.
