Mobile user experience conference 2009 - The rise of the mobile context
Improving user experienceby leveraging the contextThe rise of the mobile sensors Florent Stroppa Product Director
About me• studied electronics, optics, computer science, network architecture and MEMS• joined the mobile scene 10 years ago and still passionate about it• not a graphic designer but a UX fanatic• work with UX designers, software engineers, product managers on projects ranging from Voice, SMS services to iPhone and Web apps
Which elements deﬁne the device user experience? An engineer perspective
What form it is?Mobile phones come in verydifferent form factors.While manufacturers arecontinually coming up with newdesigns, there are severalcommon categories which canbe identiﬁed. http://www.phonescoop.com/glossary/term.php?gid=4
How does it feel?• Is it heavy or light?• Is it cold or warm?• Does it have curves or straight lines?• Does it look expensive or cheap?• How does it sound?
Which input? • Does it have a keypad? • Does it have a keyboard? • Does it have a touch screen? • Does it have a trackball?
How fast it is?• How long does it take to start an app?• How long does it take to make a call, take a picture?• How does it respond to user’s input?• How fast does it change screens?• How fast does it connect to the network?• What about network latency?
How smart it is?• Does it predict my input?• Does it predict my intent?• Does it know where I am and act upon it?• Does it do what I want to do?
While there have been strongimprovements in device design,operating systems, user interfaces,application development and networksit seems that...
Phones need to be aware of the context date, time, location, ambiance, our agenda and our relationship with others.
What is the context? Context Situation Personal Data PatternsDate and time Contacts Location Calendar Short-term Long-term Ambiance User Proﬁle New contact Call logs Proximity Photos Search Messaging New locations Previous app uses Crowd pattern Crowd pattern Physical Social context Position Social networks Activity Local news State Global news
date and time• Date : day of week, week-end, holidays, seasons• Time : day or night, alarm clock• Mash-up with Calendar data
Future is bright for sensors• In2010, about 1 in 3 smart-phones will have accelerometers.• Pressure sensors and gyroscope will follow.• The market for MEMS will top $1 Billion.
Background process• To understand environment and context, apps need to run in the background• No smart context-aware apps without background process• Android, the best platform for background process management. iPhone does not provide support for developers.

Some Apple patents... Motion sensitive UI The ﬁling, entitled Variable Device Graphical User Interface, describes a self-adjusting user interface "For example, if the user wishes to view the contact information for John Adams, the user touches the display over the area of the row for the contact John Adams," Apple says. "While the device is moving, the motion of the device can be detected. The device can change the size of the rows of the contacts in the contact list application to give the user a larger target area for each contact. For example, the height of a row can be increased. This gives the user a larger touch area with which to select a contact. In some implementations, the height of the toolbar can be increased as well."
UX work will be harder• We are going from digital to analog, from binary logic to fuzzy logic• The input is not only the user. There are also the environment, the context and the user’s data• New tools will need to be found to formalise those new aspects
Agile methodology• Agiledevelopment• Cross-functional team (ux, ui, tech, marketing)• Prototyping• Rapid and iterative process
Our experience withfuture mobile phones will be radically different
