IT systems for mobile work It is often important that information is available at exactly the right place and time Mobile systems can support work that is mobile Mobile systems can make work more mobile Usability in mobile systems is problematic Mobile usability Different technology different possibilities and problems! Examples of this? Mobile usability Environmental aspects Temperature, precipitation and lighting conditions might affect performance of mobile hardware. Noise make mobile system hard to fully interact with. Users move from place to place and mobile systems must be usable on the move. Competition for attention in multitask mobile settings Users might need to manipulate other physical objects during interaction with mobile systems. 3
Mobile usability Hardware Limitations When mobile devices are to be carried the device itself has to be small enough and easy to bring along. Speed of network traffic and connection is still relatively slow and unreliable. CPUs are slow in advantage of being inexpensive, small and less power consuming. Memory size is limited as well as its speed. Battery times are short Network connections are today unpredictable and far from geographically complete. Screen size is small and information presented is hard to read for people with bad vision. This results in bad readability and is one of the most commonly treated issues about usability in mobile systems, the design for mobile graphical user interfaces. Usability Interaction with Mobile Devices Input Write directly on the screen Mobile and smart phones also uses buttons 0-9*# for input of text. Devices with a stylus can provide a virtual keyboard Some devices offer a small hardware keyboard Technology to control IT systems with the voice IT in home care Home care Home health care, can be advanced Care for the elderly Communication E-health 4
