Having the touch area limited to the display size is OK for some user interfaces. However, there are many user interfaces that require an active touch area beyond the display area. This is typically fix function buttons or an additional area surrounding the display for gestures. Having the touch sensor elements as part of the display will restrict the type of user interface that can be used in a product.
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.
