    Emerging Linguistic Functions in Early Infancy

    This paper presents results from experimental studies on early language acquisition in infants and attempts to interpret the experimental results within the framework of the Ecological Theory of Language Acquisition (ETLA) recently proposed by (Lacerda et al., 2004a). From this perspective, the infant’s first steps in the acquisition of the ambient language are seen as a consequence of the infant’s general capacity to represent sensory input and the infant’s interaction with other actors in its immediate ecological environment. On the basis of available experimental evidence, it will be argued that ETLA offers a productive alternative to traditional descriptive views of the language acquisition process by presenting an operative model of how early linguistic function may emerge through interaction

    ARTIFICIAL REALITY INTERACTION MODELS

    In some implementations, the technology can render a dense layout of interactive mechanisms (e.g., selectable text and/or graphics) that are responsive to low accuracy input methods on the XR device. In some implementations, an XR device can associate a shortcut with the physical object (e.g., an action relative to the physical object, an option to perform an action relative to the physical object, etc.). In some implementations, a workload manager can select an augmentation workload using one or more of captured environment data (e.g., captured visual frames, audio, etc.), output from the initial stage model(s), any other suitable data

    The Effects of Sharing Awareness Cues in Collaborative Mixed Reality

    Augmented and Virtual Reality provide unique capabilities for Mixed Reality collaboration. This paper explores how different combinations of virtual awareness cues can provide users with valuable information about their collaborator's attention and actions. In a user study (n = 32, 16 pairs), we compared different combinations of three cues: Field-of-View (FoV) frustum, Eye-gaze ray, and Head-gaze ray against a baseline condition showing only virtual representations of each collaborator's head and hands. Through a collaborative object finding and placing task, the results showed that awareness cues significantly improved user performance, usability, and subjective preferences, with the combination of the FoV frustum and the Head-gaze ray being best. This work establishes the feasibility of room-scale MR collaboration and the utility of providing virtual awareness cues

    The purpose of the research was to develop an innovative human-computer interface based on eye movement and voice control. By eliminating a manual interface (keyboard, joystick, etc.), OASIS provides a control mechanism that is natural, efficient, accurate, and low in workload
