What is Hands-Free Interaction System

As computing equipment become ubiquitous, a new set of interfacing devices need to be developed and properly adapted to the conditions where this equipment is to be used. Interacting with machines might present difficulties relative to the handiness of common interfacing devices, when wearing certain clothes, doing certain dirty jobs, or when they are used by people with accessibility needs. In the last decades a new set of input devices were made available, including 3D sensors, which allow machine interacting without the need of touching any device. This chapter presents two prototype solutions supported by one of this 3D sensors, the Leap Motion, to manage appliances and other devices in a building and for the picking and loading of vehicles in a warehouse. The first case is contextualized in the area of the IoT and load scheduling of appliances, as a decisive factor in reduction of the buildings' electrical costs. The second case is presented as a solution to integrate the distribution of fresh and frozen goods where workers use thick clothes/gloves to carry out their work.
