“…In later experiments, the researchers found the same mechanism in humans and "it includes Broca's area" [226]. Mirrors neurons nicely fill the gap predicted by Chomsky and explain the fact that we extract meaning from the other person's embodied behavior and not only by speech ( [152] pp [131][132][133][134][135][136][137][138][139][140][141]. Very frequently, a gesture can convey information not present in speech [98,38].…”

“…What is the impact of such delay in the user's response time is one of the questions we will try to answer in throughout this document. For now, we must acknowledge our concern on this matter due to the finding of Jay and colleagues [136]: feedback delays as short as 50ms are sufficient to impact task performance. We posit, however, that the greater risk of task performance problems is related to how soon the user can distinguish the signal and not how fast the motor can reach full spinning speed.…”

(ABSTRACT)Mathematics instruction and discourse typically involve two modes of communication: speech and graphical presentation. For the communication to remain situated, dynamic synchrony must be maintained between the speech and dynamic focus in the graphics. Sighted students use vision for two purposes: access to graphical material and awareness of embodied behavior. This embodiment awareness keeps communication situated with visual material and speech. Our goal is to assist students who are blind or visually impaired (SBVI) in the access to such instruction/communication. We employ the typical approach of sensory replacement for the missing visual sense. Haptic fingertip reading can replace visual material. We want to make the SBVI aware of the deictic gestures performed by the teacher over the graphic in conjunction with speech. We employ a haptic glove interface to facilitate this embodiment awareness. In this research, we address issues from the conception through the design, implementation, evaluation to the effective and successful use of our Haptic Deictic System (HDS) in inclusive classrooms.

Abstract-Latency is detrimental to interactive systems, especially pseudo-physical systems that emulate real-world behaviour. It prevents users from making quick corrections to their movement, and causes their experience to deviate from their expectations. Latency is a result of the processing and transport delays inherent in current computer systems. As such, while a number of studies have hypothesized that any latency will have a degrading effect, few have been able to test this for latencies less than ∼50 ms. In this study we investigate the effects of latency on pointing and steering tasks. We design an apparatus with a latency lower than typical interactive systems, using it to perform interaction tasks based on Fitts's law and the Steering law. We find evidence that latency begins to affect performance at ∼16 ms, and that the effect is non-linear. Further, we find latency does not affect the various components of an aiming motion equally. We propose a three stage characterisation of pointing movements with each stage affected independently by latency. We suggest that understanding how users execute movement is essential for studying latency at low levels, as high level metrics such as total movement time may be misleading.

“…Afterwards, studies involving tactile sense system, motion platform, and flight simulation followed aiming at the delivery of physical responses in virtual worlds to users [4,5]. For the purpose of overcoming the restrictions of limited space depending on HMD, CAVE (Cave automatic virtual environment) has been studied, which enhances immersion by manufacturing a cube space of a certain size and projecting image information that corresponds to the previously computed users' sight on the wall by a projector [6].…”

This study proposes a method of effectively creating mobile virtual reality scenes centered at events for the purpose of providing new experiences in virtual reality environment to users. For this purpose, this paper uses Prim's maze generation algorithm to automatically create maze environments that have different patterns every time and to compute mazes with finite paths. This paper designs a scheme of creating virtual reality scenes based on event-centered mazes to maximize users' tension and immersion. Here, event components that are appropriate for the maze environment are defined and maze patterns are created centered at the event point where events that are appropriate for the maze pattern are automatically created. Finally, the paper analyzes whether the proposed virtual reality scene based on event-centered mazes is helpful in enhancing users' immersion and arousing their interest through diverse experiments.
