2 Sep 3, 2008NVOSS 20082 Introduction The iPortal is a web-app for the iPhone / iPod Touch providing a mini portal to VO data and services. Standard CGI-based web-app using VOClient tools on the server-side, and CSS to fit the iPhone screen size. Fully functional prototype to demonstrate capabilities.

3 Sep 3, 2008NVOSS 20083 Screenshots Single textbox entry –Object Name –Coordinates –Search Terms Modifiers used to restrict search (e.g.i:m51 to search only images services)

4 Sep 3, 2008NVOSS 20084 Screenshots Tapping the textbox brings up the built-in keyboard interface automatically

5 Sep 3, 2008NVOSS 20085 Screenshots Task tries to resolve term either via Sesame or the Registry If object, an image is displayed and the coordinates printed The i button brings up additional image controls

6 Sep 3, 2008NVOSS 20086 Screenshots Image controls allow Pan / Zoom Controls done using JavaScript Images in SDSS footprint are in color, otherwise DSS, but all-sky coverage

7 Sep 3, 2008NVOSS 20087 Screenshots Search terms bring up summary of results Selecting a type shows resources only of that type

8 Sep 3, 2008NVOSS 20088 Screenshots Titles of services displayed in list The Q button is a shortcut to a query form of that service

9 Sep 3, 2008NVOSS 20089 Screenshots Selecting a title shows the full Registry record Again an option to query the service, this case a VizieR table

10 Sep 3, 2008NVOSS 200810 Screenshots Full access to the table is allowed by 2- fingered scrolling Result is a simple HTML table

11 Sep 3, 2008NVOSS 200811 Screenshots Sample of a query form for an image service Input can be position or object name

12 Sep 3, 2008NVOSS 200812 Screenshots SIAP results will show preview images as links A service to render FITS images could be written

15 Sep 3, 2008NVOSS 200815 What About Normal Cell Phones? Usually come w/ smaller screens (e.g. 160x128). Recently 320x200 is common. MVO is a web-app for these small screens. Emphasis on basic query, no data access allowed

16 Sep 3, 2008NVOSS 200816 MVO on Cell Phones Resolver mode output pretty basic. Just enough to point a telescope if youre in a field with your telescope but no internet connection.

17 Sep 3, 2008NVOSS 200817 MVO on Cell Phones Registry search prints ShortName owing to small screen size Each item is a link that clicks thru to the full Registry record.

18 Sep 3, 2008NVOSS 200818 MVO on Cell Phones Registry records prints essential fields. Enough information to know what the resource is, but we restrict printing (e.g. long descriptions) to minimize data transfer.

19 Sep 3, 2008NVOSS 200819 MVO on Cell Phones Inventory mode prints a simple count of matched resources and records found in a 10 radius. Result is the resource Title since these are typically Vizier tables. Cluck thru to full resource record
