Smartphone Factor

Smartphones Users

[Smith, A., Smartphone Adop+on and Usage, Pew Research Center's Internet & American Life Project, Pew Internet & American Life Project, July 2011]

•  6 billion mobile phone subscribers •  83% US adults have a cell phone of some kind: 42% - smartphone

–  87% of smartphone owners access Internet/email on phone, 68% - daily

Smartphones Users

•  How far is your phone? •  53% arm & 88% room level

•  What factors in#uence your smartphone experience?

AAL: Example Technical Challenges

•  Performance –  ‘Best-effort’ network

infrastructures –  Delays: one way or round-

trip delays –  Throughput: consumer-

producer paradigm •  Mobility: horizontal and

vertical handovers –  Intra- and inter-operator

•  Scalability

•  Data priority over voice •  Communication costs

–  Per MByte vs. ‘#at-rate’ •  Security and Privacy

–  Data encryption •  Power consumption •  Miniaturization of sensors/actuators •  Service personalization

–  Individual user’s needs •  Standardization and interoperability

[Papers: Wac et al., IEEE COMMAG‘12, IEEE TMC‘12, ACM UBICOMP’11, IEEE JSAC’09]


22

Recommendations

•  Challenges Ahead –  User acceptance –  Privacy, trust –  Interoperability, standardization –  Evaluation methods vs RCT –  Organizational issues, pathways –  Legalization, liability –  Financial aspects,

reimbursements

•  Recommendations –  mobile solutions technologically

feasible for non-critical cases –  Inter/trans-disciplinary approach

needed •  User-centered design

–  Bridge the gap via an open, trustworthy dialogue

–  Encode implicit expectations & requirements

–  Innovation: “who’s turn is now”? •  Innovating the intervention

content vs the IT infra.
