Beyond usability: the OoBE dynamics of mobile data services markets

With processors imbedded in appliances, cars, books, and other retail products, modern society has entered the world of pervasive computing. Yet few consumers are able to set up new digital devices and integrate them into everyday life. From this perspective, the data-enabled mobile phone leads the way. In many markets, mobile phones have a product life cycle of 12 months or less. Some subscribers are able to put their new phones to immediate and full use. For others, the learning curve is so steep that they move on to a replacement without having learned to exploit the functionality available in the first one. This work applies earlier findings by IMARC researchers in segmenting mobile data services (MDS) markets, interprets recent survey data, and synthesizes a model to guide design of the Out-of-the-Box Experience (OoBE) for mobile data subscribers. This integrative model can be applied across cultures to help service developers, facilitators and operators design, distribute and communicate new MDS to fulfill the demand side requirements of potential adopters, and to guide packaging design to improve user experiences during the early stages of use.

The Relevance of Laboratory Studies to Practical Situations

By their very nature laboratory experiments are at best only rough and approximate models of any real-life situation. First of all the possible independent variables that influence behaviour in any practical situation, a laboratory experiment selects only a. few for test. As a result, hidden or unsuspected interactions in real-life may easily nullify, or even reverse, conclusions arrived at in the laboratory. Second, variables always change when they are brought into the laboratory. Third, the effect of controlling extraneous or irrelevant variables in the laboratory is to increase the precision of an experiment but at the risk of discovering effects so small that they are of no practical importance. Fourth, the dependent variables (or criteria) used in laboratory experiments are variables of convenience. Rarely are they selected for their relevance to some practical situation. Last, the methods used to present variables in the laboratory are sometimes artificial and unrealistic. The safest and most honest conclusion to draw from all these considerations is that one should generalize with extreme caution from the results of laboratory experiments to the solution of practical problems.

Searching for variable-speed motions in long sequences of motion capture data

Motion capture data digitally represent human movements by sequences of body configurations in time. Subsequence searching in long sequences of such spatio-temporal data is difficult as query-relevant motions can vary in execution speeds and styles and can occur anywhere in a very long data sequence. To deal with these problems, we employ a fast and effective similarity measure that is elastic. The property of elasticity enables matching of two overlapping but slightly misaligned subsequences with a high confidence. Based on the elasticity, the long data sequence is partitioned into overlapping segments that are organized in multiple levels. The number of levels and sizes of overlaps are optimized to generate a modest number of segments while being able to trace an arbitrary query. In a retrieval phase, a query is always represented as a single segment and fast matched against segments within a relevant level without any costly post-processing. Moreover, visiting adjacent levels makes possible subsequence searching of time-warped (i.e., faster or slower executed) queries. To efficiently search on a large scale, segment features can be binarized and segmentation levels independently indexed. We experimentally demonstrate effectiveness and efficiency of the proposed approach for subsequence searching on a real-life dataset.

The development and application of CAD/CAM workstations in the GDR

For accomplishing low-attended manufacture, step by step, it is necessary that information handling in technological production planning, management and shop control processes is organized economically. This is especially true with respect to computer-aided product development and production planning, faster order throughput, control of production equipment and delivery of information needed for high equipment utilization with a simultaneous increase in the volume of data processed automatically. These complex requirements call for a new type of approach in information handling technology (CAD/CAM) and corresponding layouts of workstations for the designer and manufacturing engineer. Such CAD/CAM facilities should be user-friendly so that they can be adapted to the user's need and not vice versa.     

The value of storyboards in the product design process

In the realm of product design, communication between designer, client, design team and future users is of great importance. Throughout the design process, ideas and concepts are generated and must be conveyed to these people to evoke comments, judgement or acceptance, depending on the process phase. Storyboards are a valuable aid to the designer in this task by providing a common visual language that people from different backgrounds can ‘read’ and understand. However, the visualisation style of the storyboards influences the reactions. Where open and sketchy storyboards are inviting comments, sleek and detailed presentations can be overwhelming. Storyboards not only help the product designer to get a grip on target groups, context, product use and timing, but also in communicating about these aspects with all people involved. This paper is part of the 3AD design colloquium Creative connections [1].
