Mobile Accessibility for Android is a combination of a suite of accessible apps and a screen reader which provide accessibility on Android devices for blind and visually impaired users. Main functionality of Android devices is made available to the user through Mobile Accessibility's voice and Braille based UI. This paper describes the process of integrating this commercial product with GPII/Cl...

Mobile phones are increasingly able to read auto-id labels, such as barcodes or RFID tags. As virtually all consumer products sold today are equipped with such a label, this opens the possibility for a wide range of novel digital services building on physical products. In this paper, we discuss the problems that arise when such novel applications are deployed and present a Browser for the Inter...

1 This work is partly supported by the German Ministry of Education and Research under IPonAir Project Abstract : This paper describes the system design and implementation of a testbed, running at TSystems in Darmstadt. In this testbed the interworking between mobile wireless ad hoc networks (MANETs) and infrastructure based networks, based on the IPv6 protocol is investigated. This means, acce...

Wearable computing along with advanced mobile communication has the potential to revolutionise the working environment and working processes of the mobile worker of the AEC industry. While wearable computing allows the mobile worker to execute his/her work and tasks more efficiently and safer with the support of information provided by novel user interfaces, like augmented reality glasses and v...

We are pursuing a bottom-up exploration of the evolution of behaviours involving collective locomotion of numerous miniature autonomous mobile robots. Collective locomotion is a subset of collective robotics [Bonabeau & Theraulaz 94] which focuses on the specific tasks required to move a group of autonomous agents (e.g. mobile virtual or physical robots) from an origin to a destination. It deal...

The rapid development of mobile commerce (m-commerce) has profound influence on logistics industry. Firstly, through analysis that combines m-commerce and the logistics industry, the paper draws a conclusion that main m-commerce applications in logistics industry include cargo tracking, mobile inventory management, vehicle positioning and M2M (machine to machine) mobile services. Then, we think...

I estimate demand for auto insurance in the presence of two types of market frictions: search and switching costs. I develop an integrated utility-maximizing model in which consumers decide over which and how many companies to search and from which company to purchase. My modelling approach rationalizes observed consideration sets as being the outcomes of consumers’ search processes. I find sea...
