Years ago we had a computer game joystick with significant tactile feedback. While the effect was surprising and novel, it wasn't engaging enough to spawn a wide following nor to motivate us to upgrade the software on subsequent computers. Since then, the "wii" personal game controllers have tactile feedback which is very convincing. One challenge that Disney will likely face is that of cleaning and maintaining the haptic devices for public venues. Movies are remotely sensed so the sound and image displays don't need to be cleaned after use. Tactile devices will need a nice easy to clean interface - as well as a compelling user experience.
There are any number of applications like videogames for this technology, but the real elephant in the room is the adult video industry (tell the truth: Did any of you reading this article not think of porn?). That means that there is a legitimate business case for it, as well as cover provided by the other applications. Maybe it's just me being cynical (again), but that sounds like the recipe for a successful technology.
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.
