Mobile information
for this session we looked at the pros and cons of mobile information services IE context awareness for GPS locations and the limitation of screen and keyboard sizes.
Context awareness, GPS can provide web searches with local results provided by satellites pinpointing the location of the hardware to within 40 meters, most smart phones contain this capability and they also have compass and accelerometer capabilities so will know with direction you are facing which is useful for gaining directions via a piece of mapping software, it also allows you to geotag pictures and also access local information via wikipedia or alike.
how bluetooth can be used to send advertising to people discreetly and also the privacy issues with bluetooth.
the problems of limited screen size, how web sites provide mobile versions of their sites that allow easier navigation by a mobile devise and how servers can throw away information not needed by the user. it also can recognise the OS of the device and could in theory only send compatible information to the device but the technology isn't quite there for that yet.
how Mobile sites should be designed with the Mobile device in mid, keeping the need to scroll to a minimum, keeping graphics low, and all but basic navigation removed.
Keyboard size, the trade off with button numbers and size, the use of virtual keyboards on touchscreen devices how their are different keyboards for different tasks, the use of auto complete and the emergence of gesture control.
we then looked at what people actually use their mobile device for, mostly trivia and local information.
finally we looked at the combination of social media and location services and how this can add rich metadata to photos ect but also allow for serious privacy breaches.
during the lab session we discussed what a city student would want out of a mobile information app. we talked about using augmented reality to help guide someone around the campus, acess to the library catalouge, the inclusion of a social network to discuss lectures and recieve timetable changes.
