One-handed keyboard helps mobile and disabled workers
Abstract
FrogPad Inc. has developed a keyboard that can be used with one hand. The keyboard - designed for use with desktop computers, cell phones, or PDAs -could help mobile workers who don't always have both hands free or disabled people who have the use of only one hand. FrogPad works with various techniques to give its 20 keys all of the functionality of a traditional keyboard and even that of a 10-key phone or calculator.
... Some field workers are well skilled in utilizing computer keyboards and use them more efficiently than handwriting. In this area, several improvements regarding user's input capabilities had been suggested in the past, e.g., one-handed keyboards [10], wrist-mounted keyboards [4], or even utilizing an invisible keyboard ([8], [12]). However, the usage of one-handed keyboards require additional training and thus can't be applied in the daily service business. ...
Utilizing mobile applications in the area of industrial field service promises several benefits, especially improved process support providing tailored service information and presenting it in an ad-hoc manner. The suggested approaches up to now are more or less beneficial or can't be applied in this area at all due to some assumptions that can't be perpetuated in most cases. In this paper, we describe the results of our evaluation of current approaches in the development of mobile applications. We discuss inhowfar these approaches can be used in industrial field service arguing their pros and cons. Based on the results of our case studies, we give some advices regarding which of the presented approaches are less suitable for industrial domains and which should be considered for further investigation.
The Sol Genomics Network (SGN, http://solgenomics.net) is a web portal with genomic and phenotypic data, and analysis tools for the Solanaceae family and close relatives. SGN hosts whole genome data for an increasing number of Solanaceae family members including tomato, potato, pepper, eggplant, tobacco and Nicotiana benthamiana. The database also stores loci and phenotype data, which researchers can upload and edit with user-friendly web interfaces. Tools such as BLAST, GBrowse and JBrowse for browsing genomes, expression and map data viewers, a locus community annotation system and a QTL analysis tools are available. A new tool was recently implemented to improve Virus-Induced Gene Silencing (VIGS) constructs called the SGN VIGS tool. With the growing genomic and phenotypic data in the database, SGN is now advancing to develop new web-based breeding tools and implement the code and database structure for other species or clade-specific databases.

Mobile solutions provide the opportunity for seamless integration of mobile field service engineers into the service processes resulting in new form of interaction between them and the dispatcher. In this paper, we describe the results of our study regarding the requirements of utilizing a mobile application in the area of industrial field service. After a brief description of the challenges these kinds of application shave to face and an overview of the utilized mobile service system architecture, we present the results of our usability study followed by a discussion.
We present in this paper the architecture and some implementation details of a web-based version of a Trivial game. Our implementation
achieves such a high degree of interactivity between the players that they perceive the game as being played in real-time.
More importantly, no plug-in or applet is used in the architecture of the system. These properties are achieved by means of
a carefully designed architecture that uses AJAX (Asynchronous JavaScript and XML) for data exchange. Using this approach, it is possible to develop any type of web-based collaborative software with few
load on the web server. In the paper, we analyze traditional architectures for web-based applications and we show how our
approach overcomes their limitations. Furthermore, we proof the efficiency of our approach by means of an empirical comparison.
