Originally getting their start in the early 1980s as membrane or screen-printed switches for keyboards and keypads, these types of switches were initially met with resistance due to their poor performance and lack of tactile feedback.

The problem is that motion sensing can require expensive digital sensors that are difficult to interface with. In addition, once the data is received, algorithms still need to be developed to detect the motion, which is a non-trivial endeavor.
