mobile search “Students are results – oriented and value convenience. This emphasis coupled with the design constraints on some devices promotes a need to get to relevance quickly. Socialization, personalization and location awareness become very important” Lorcan Dempsey, Vice President and Chief Strategist, OCLC “We conjecture that new breakthroughs in information retrieval will not come from smarter algorithms that better exploit existing information sources, but from new retrieval algorithms that can intelligently use and combine new sources of contextual metadata.” Bennett et al., 2012 (SIGIR 2011 Conference) "Mobile devices will be most individuals’ primary electronic device used for their calendar, voice and e-mail, small scale video, learning, surfing, search, GIS, etc – basically most everything. This moves the virtual world from home or office-based computing to truly personal computing." Stephen Abram, Vice President of Innovation, SirsiDynix Abbott, J. (2012).

Information Physical Space growing demand for the ability to use mobile devices in the workplace raises concerns about data loss and information security CSA Mobile Working Group (2012) Mobile Networks surging demand for mobile access to high-bandwidth multimedia (Youtube videos, etc.) may soon outstrip the capacity of existing mobile networks BBC News (2012a) barriers to internet access:
(1) service gaps in rural and remote areas
(2) financial cost of obtaining access
(3) lack of computer literacy cloud computing services provide a way of outsourcing computational resources, which helps to compensate for the performance limitations of mobile devices Cloud Computing mobile cloud computing = major research area bodes well for the creation of more efficient (and affordable?) devices, but raises concerns about privacy and the protection of personal information Privacy “big data” = mining data to support highly personalized advertising and a streamlined consumer experience
widely regarded as the future of advertising, but at what cost to privacy? Houpt (2012) recent IBM survey found that people are increasingly willing to trade personal information for a more personalized consumer experience
user education about privacy concerns remains a significant challenge Skariachan (2012) Information Security • greater integration with work and business = greater need to control access
• if authentication is awkward or confusing, then users will go elsewhere
• balance between ease-of-access and appropriate level of information security Zhou, Broussard, & Lease (2011) mobile devices
