Emerging Natural User Interfaces in Mobile Computing: A Bottoms-Up Survey

摘要: Mobile and wearable interfaces interaction paradigms are highly constrained by the available screen real estate, computational power resources. Although there exist many ways of displaying information to mobile users, inputting data a device is, usually, limited conventional touch based interaction, that distracts users from their ongoing activities. Furthermore, emerging applications, like augmented, mixed virtual reality (AR/MR/VR), require new types input methods in order interact with complex worlds, challenging traditional techniques Human-Computer Interaction (HCI). Leveraging Natural User Interfaces (NUIs), as paradigm using natural intuitive actions computing systems, is one meet these challenges its modern applications. Brain-Machine enable thought-only hands-free Myoelectric track body gestures gaze-tracking - examples NUIs applicable interactions. The wide adoption devices penetration technologies, alongside growing market AR/MR/VR, motivates exploration implementation paradigms. concurrent development bio-signal acquisition accompanying ecosystems offers useful toolbox address open challenges. In this survey, we present state-of-the-art methods, summarize evaluate recent developments area outline potential application scenarios. survey will provide bottoms-up overview starting (i) underlying biological aspects signal techniques, (ii) portable NUI hardware solutions, (iii) NUI-enabled well (iv) research problems.
