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

MVO on Cell Phones
• Resolver mode output pretty basic.
• Just enough to point a telescope if you’re in a field with your telescope but no internet connection.

MVO on Cell Phones

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.

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.
