The use of miniaturized optical sensors as input devices based on speckle phenomena will be discussed alongside with some considerations on the path to industrial implementation. Based on two examples from the field of cursor control systems, the future opportunities for dissemination into industrial applications will be discussed, in particular, optically based systems for monitoring dynamics of solid structures, e.g. rotational speed, torsional vibrations and velocity. Here, the commonly restrictions for a successful implementation, i.e. reliability, miniaturization, accuracy and especially price will be dealt with. Besides, some general remarks on my observations on bringing ideas from the lab into commercial products will be offered.
