One bothersome point ignored in the article is the problem of finger-smudges on the touchscreen.
While this is not much of an issue for user input displays, such as touch-keyboards, -menues, or -icons, it is a serious problem when the touchscreen is used also for output of text or images.
A dirty keyboard or mouse can be ignored; a dirty touch display is very aggravating.
Users will persist in eating while browsing; this almost unavoidably means the use of a pen (or chopstick?) for touchscreen input.
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
