Most current e-commerce transactions are conducted by users in fixed locations using workstations and personal computers. Soon, we expect a significant portion of e-commerce will take place via wireless, Internet-enabled devices such as cellular phones and personal digital assistants. Wireless devices provide users mobility to research, communicate, and purchase goods and services from anywhere...

Effective interface design for mobile handheld devices facilitates user adoption of mobile commerce (m-commerce). Current wireless technology poses many constraints for effective interface design. These constraints include limited connectivity and bandwidth, diverse yet simplistic devices, the dominance of proprietary tools and languages, and the absence of common standards for application deve...

As broadband wireless access technologies mature and portable handheld devices including cell phones are equipped with more capabilities, mobile ad hoc networks are easily deployed. Various applications and services including location-based services and mobile advertising provide opportunities for new businesses.

field police officers operating in the district of Groningen North (Netherlands), equipped with PDAs through which they ubiquitously access information while on the move; students of the Massachusetts Institute of Technology (i.e. MIT, USA), equipped with laptops in a campus where wireless Internet connectivity is ubiquitous; all subscribers and roamers using their mobile phones in the Amsterda...

As the name suggests, wireless systems operate by transmission through space rather than through wired connection. There are two major problems to be addressed in a wireless setting that do not arise in the wired case. The first is that the channel over which communication takes place is time varying. The second being interference between multiple users using a common communication medium. Ther...

Mobile phones have been proclaimed as the new service frontier. Nowadays, in addition to traditional mobile services, new mobile commerce services are ready to be used by customers based on 3G-related technologies. However, little is known about the reasons why different groups of customers adopt mobile commerce services. By means of a sample of 542 Dutch consumers, we analyze the acceptance of...

A variety of communication problems is a common phenomenon in the current hospital setting. Physicians need a mobile context-aware communication system in their daily practice. Our approach, based on an initial study performed at the Oncology Department at the University Hospital of North Norway and an extensive collection of user needs according to CSCW and use case methodology, will develop a...

Shoogle is a novel interface for sensing data within a mobile device, such as presence and properties of text messages or remaining resources. It is based around active exploration: devices are shaken, revealing the contents rattling around “inside”. Vibrotactile display and realistic impact sonification create a compelling system. Inertial sensing is used for completely eyes-free, singlehanded...

The Wireless Application Protocol (WAP) is an open, global specification that empowers mobile users with wireless devices (such as mobile phones) to easily access and interact with information and services on the Internet. Although some components of the WAP suite have been developed, it lacks a complete general architecture integrating software components of both the Internet and wireless cont...
