SkyMouse: A light-weight information collector

• Not like some VO efforts on uniformed access systems, for example, NVO DataScope, SkyMouse tries to show a comprehensive overview for a specific object, but not to snatch as much data as possible.

Characteristics

• Easy of Use. Access to world wide astronomical references, catalogs, images, and maybe more, by a simple “MouseOver” action.– Traditional query system: Copy your words->Open Web

Browser>Visit Astronomical Database website->Select service->Paste->Custom Options->Submit

Technic Highlights

• “Screen character capture” technic developed independently.

• Web 2.0 technologies:– AJAX, provides smoothly response and better us

er experience.– .Net framework, the backend system is based o

How the SkyMouse works?

• Characters on the screen are captured by the client, then will be sent to SkyMouse server after simple analyse. SkyMouse server accepts item from the client and then sends it to name resolving service of SIMBAD or NED for further information, esp. coordinate. Different databases will be queried using the coordinate and object name. SkyMouse server collects results and displays them in user’s default web browser. – (without cash)
