Emerging ExG-based NUI Inputs in Extended Realities: A Bottom-up Survey

چکیده
Incremental and quantitative improvements of two-way interactions with e x tended realities (XR) are contributing toward a qualitative leap into state XR ecosystems being efficient, user-friendly, widely adopted. However, there multiple barriers on the way omnipresence XR; among them following: computational power limitations portable hardware, social acceptance novel interaction protocols, usability efficiency interfaces. In this article, we overview analyse natural user interfaces based sensing electrical bio-signals that can be leveraged to tackle challenges input interactions. Electroencephalography-based brain-machine enable thought-only hands-free interaction, myoelectric methods track body gestures employing electromyography, gaze-tracking electrooculography examples bio-signal technologies united under collective concept ExG. ExG signal acquisition modalities provide interact computing systems using intuitive actions enriching XR. This survey will bottom-up starting from (i) underlying biological aspects techniques, (ii) hardware solutions, (iii) ExG-enabled applications, (iv) discussion such applications technologies, as well (v) research challenges, application directions, open problems; evidencing benefits ExG-based Natural User Interfaces inputs introduce area

Bottom - Up Query Evaluation in Extended Deductive Databases
Semantics Many concrete semantics have been defined by selecting either a specific model of every logic program (such as the well-founded model) or a set of models (such as the stable models). Furthermore, also semantics which define a program completion comp(P ), simply select a subset of the models of P by adding formulas to P . So it seems that the following definition is very wide: Definiti...
متن کاملMobile augmented reality survey: a bottom-up approach
Augmented Reality (AR) is becoming mobile. Mobile devices have many constraints but also rich new features that traditional desktop computers do not have. There are several survey papers on AR, but none is dedicated to Mobile Augmented Reality (MAR). Our work serves the purpose of closing this gap. The contents are organized with a bottom-up approach. We first present the state-of-the-art in sy...
متن کاملComposition and Decomposition of Extended Multi Bottom-Up Tree Transducers?
Extended multi bottom-up tree transducers are de ned and investigated. They are an extension of multi bottom-up tree transducers by arbitrary, not just shallow, left-hand sides of rules; this includes rules that do not consume input. It is shown that such transducers can compute all transformations that are computed by linear extended top-down tree transducers (which are a theoretical model for...
