Ubiquitous Computing
• Extent of social adoption of Location-based Services (LBS), Volunteered Geographic Information (VGI) and digital globes has been unprecedented
• This phenomenon is rapidly being adopted, therefore we aim to study and test apps to

Dynamic Static
Type LBS Real time updated location-based information provided to the user.
Static location-based information is provided. The information does not change in real time based on events.
Example Bus real-time location from GPS signal on bus, New sales or promotions, current temperature
Bus schedule, Restaurant Menu, weather averages for that location

Classifications of LBS
Active/Manual Passive/Automated
Type of VGI Real time information (qualitative or quantitative) provided by the user actively and consciously.
The volunteer’s device is contributing the geographic information running in the background using the tools associated with the device (ex. GPS, Accelerometer), possibly unknowingly by the user
Example Live Twitter, Checking-in via Yelp, Facebook, Foursquare, business review
GPS tracking of an individual, geotagged photos

VGI Interface: Check-in, or Add Information
“Ubiquitous electronics rarely contribute to our sense of group identity or resonate with us like a physical place” (Burke, 2008).

The Geoweb is turning into aNegotiated Environmental Topology (NET)
Not about the technology itself but what it facilitates…
Negotiation between• Individuals• Automated Sensors • User networks
(applications)• Geocoders
LBS mediated experiences
<� L � hã KU
Perhaps LBS mediate spatial
experiences resulting in a
limited mental map of the world
Good Bad
•Students are excited to use mobile computers.
•Ability to access and disseminate large amounts and diverse data.
•Exposing large populations to ideas related to GIScience! (Crampton,
2009; Haklay & Singleton, 2009 ; Goodchild, 2007; Lake & Farley, 2007; Turner, 2006).
•Fragmented attention (Spence and Feng, 2010; Montello and Freundschuh, 2005; Willis et al., 2009).
•Passive interaction
•Poor memory for distance •Disconnect between LBS and real environment (Willis et al., 2009).

Mobile Mapping: Good and Bad
<•L��ã��
There is hope!
• Willis et al.; 2009 Offers following suggestions for mobile mapping application design– Design a pre-task
– Self report to encourage active engagement
– Short tasks that can be reviewed later
– Cue-match from LBS to real world
