1.3.2 Lack of Focus using barcode encoding for java control to generate, create data matrix 2d barcode image in java applications. isbn 13 The primary focus of the m awt datamatrix 2d barcode obile user is seldom on the computing task (although, obviously, there are exceptions to this, but we are talking about the majority of time when the user has a device and is mobile). This is the primary reason for the necessity of active transactions. While a user is driving from work to home, the task of driving takes the primary focus.

During this time, if the stock price of one of the user s holdings begins to plummet, he or she cannot sell it before it falls too far. The user either does not know of the plummeting price at all or is not focused on checking on the stock price at regular intervals. Mobile users are typically mobile because they are moving between two points with the primary task of reaching the destination.

Another reason for lack of focus is multitasking. Mobile users often multitask. For example, a user may be driving and talking on the phone.

Another example could be a user who is entering some data into a PDA out in the eld (collecting information on power lines as a eld electrician, measuring environmental effects as an environmental engineer, etc.) while doing the primary eld work task at the site (such as climbing a pole and paying attention to power lines, nding the right place to measure, and keeping the environmental conditions stable while measuring, etc.).

Because of this multitasking nature of the mobile user, a variety of user interface input types such as voice may be needed to take advantage of the senses that are not preoccupied by another task. Also, the user interface to the system must be very user friendly and require as few of the user s senses focused on communicating with the machine as ef ciently as possible. For example, voice user interfaces allow users to focus on driving while still getting whatever information they need from the system.

. INTRODUCTION TO MOBILE COMPUTING 1.3.3 Immediacy Mobile users are often in a situation where they need to quickly perform one or more computing tasks, such as retrieving contact information, sending a voice or e-mail message, or triggering some remote process. They don t have the time to go through a long boot sequence or long application setup times. Mobile users normally have higher expectations of performance from their devices than stationary users do.

Performance of mobile applications is not an afterthought as it often is in the development of stationary applications. A short delay in application responsiveness can decrease its usefulness enormously. For example, a user who cannot get the necessary contact information from a mobile contact application will eventually become frustrated and use a directory service to nd the necessary contact information in urgent situations.

It is also important to note that there are different types of immediacy. For example, the user s tolerance, depending on the application, will vary in rst connecting to the network compared to the system response time. The types of immediacy depend on the application.

. 1.3.4 Abrupt Changes in Tasks As we mentioned before, th e mobile user is typically mobile because he or she is focused on something else other than computing. For example, many mobile users will try to use commute time: Whether in a train, in a plane, or in an automobile the user will be distracted by different environmental factors. These factors must be kept in mind in designing and implementing the ow and, once again, the interface of the application.

The mobile user needs to be able to stop performing some computing task abruptly, do something that may be completely unrelated, then return to the application after some unknown period of time, and, without much effort to remember what he or she had been doing, continue the computing task. Mobile users expect applications that ow smoothly and do not require complex navigation despite the abrupt nature of their actions..
