IntroductionTraditional pan and zoom techniques pose a challenge when navigating large information spaces on smartphones and other small-form-factor mobile devices. Our most recent project is ZoneZoom. - Divide view into nine segments
- Map each segment to one of the number keys on a cel phone
- Press number key: animate view to show selected segment
- Quickly release key (tapping): view stays on selected segment
- Releases key after holding down for more than a moment: view returns to the original view ("glance" at different areas)
- Redivide current by pressing on the pound # key
We have optimized a specific implementation of the ZoneZoom technique for user as a Seattle area traffic conditions map navigator called SmartPhlow. A comprehensive explanation of the ZoneZoom technique is included in our AVI 2004 paper. SmartPhlow downloads a very small amount of data (250 bytes) from the WSDOT web site. This data is then used to change the color of road segments on a navigable map. We encourage you to download SmartPhlow and install it on your own Microsoft Smartphone! |
