For tablet and smartphone application, Android might have advantage over others since the success of these products are heavily relying on the marketplace. Ubuntu, no doubt, will get some attention. In typical embedded application, memory footprint becomes very critical. The lesser the memory; the better popularity. For this reason, FreeRTOS gets a lot of attention. Commercial OS will likely be around for a while. Defense industry uses might be one of the many primary reason. I am very interested in learning the breakdown of various OS to industries/ applicatons.
The success of Android does not surprise me. The programming is very simple. The development tools are really comfortable to use. I think Android will also make its way in user interfaces in the industrial context.
OOPS, sorry, I switched colors so your comment is right. I wonder however if those figures (all, no only for uC/OS) refer to effective use or are only "intend to use sometime in the future". I remember a few years ago this issue was raised for this or another similar research.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
