This project was carried out by one of Wipro's offshore development centre for its North American client. The final product, on which the browser would run, was itself a 'wireless web browser' - a web tablet designed specifically for browsing and emailing.

The requirements for this project were in line with a VOIP telephone which had a LCD panel, on which the browser was running. This was given as a reference for our requirements.

A broad list of functions of the embedded browser, were derived by Wipro's development team from the information provided by the customer.

	2D browser
	Monochrome
	SSL support would be present
	Runs on VxWorks
	Should be able to support Java in future

The system used a client - server model, wherein any query would be sent using a proprietary protocol to the server which would be sitting at the ISP's place. The server, a faster machine would access the site, translate it to simple data and send it back to the dumb embedded system which would simply display the data on the screen. The below diagram gives an idea of this approach.

Design of embedded browser for hand held device.

Because of the non availability of hardware it was decided to simulate the product on a PC based target. This decision turned into an advantage since, the PC target gave the assurance of time tested hardware.

	Floppy disc simulating flash to store bookmarks, contact details and mail ids in files.
	Touch screen simulation.
	Proprietary protocol for interacting with web server.
