Interact with the nearby device through a webpage

We have a unique challenge with our web application. We need to be able to communicate with physical devices and have the ability to install necessary software on our clients' computers. The burning question is: Is there a way to achieve this without relying on ActiveX controls?

One potential solution I've considered is installing a tailor-made webserver on each client's machine, allowing JavaScript on our webpage to interact with that server. A similar concept can be seen in how uses JavaScript to access subdomains linked to 127.0.0.1 like . However, this approach presents challenges such as conflicts over port 80 or an undesirable reliance on nonstandard ports for our web application.

Are there any alternative strategies we should consider to address this issue?

Just to clarify, our clients will utilize standard PCs running Windows. Our goal is to establish communication between these PCs and physical devices, including a signature pad. Ultimately, we want users to sign the pad and see their signature displayed on the web page.

Answer №1

In my opinion, relying on browser-based solutions may not be the most suitable option due to numerous security concerns. Instead, developing a desktop application that integrates certain web features could be a more secure alternative.

Answer №2

Utilizing web servers and possibly embracing comet technology seems like the most promising path to take.

Web servers have the flexibility to operate on a variety of ports, assuming there are no restrictions from firewalls or configurations preventing http traffic flow. However, sticking with port 80 is always a safe choice.

In order to communicate with the mini web server, integrating with the device will be necessary. Considering your .net background, incorporating linux, apache, and mono on these devices could present some challenges - feasibility is uncertain.

This project sounds incredibly exciting and full of potential.
