At the end of the MULTITOUCH project, we capitalized on all of our diverse scientific findings, resorting from the multiple disciplines and fields of study addressed by the ESRs of MULTITOUCH, to propose an effective informational handbook targeting researchers and practitioners in haptics. We expect the information from the handbook to be useful and informative to new projects, inspire new scientific directions and discoveries in multimodal haptics, but also inform design and development of practical applications spanning from mobile devices to wearables to VR environments. Our handbook is structured in several one-page easy-to-digest chapters that feature main findings, implications, and possible applications. Moreover, the handbook features a selected set of key references to scientific papers that were published within the MULTITOUCH consortium.
