Many recent games, such as racing and flight open their game telemetry data to users by storing them in the local memory. Such can provide useful information for haptic rendering, this advantage has been exploited industry. This approach applies any applications that export run time. The rendering module operates a separate process accesses parallel with application. It is simple, efficient, modular while retaining application intact. We examine approach's viability user experience...

It is required to simulate the tactical moving objects such as combat plane, naval vessels, and submarine for performing performance functional testing of target management system. not possible collect data various circumstances due military security. To solve this problem, in paper, we have proposed a generator test set objects. The method classify three types submarine, generate elevation, velocity, movement different pattern by types.

On a battlefield, tactical moving objects, such as airplanes and tanks, need to track monitor. It is crucial for headquarters know the event occurrence, especially complex events, of objects in real time, jet fighter invading ship collision. However, radars or other sensors are only able detect primitive simple events objects. challenge manage large amounts incoming analyze their relationships infer time. In this paper, we provide clear solution dealing with challenges by using processing...

A motion effect, the vestibular stimulus generated by a moving chair, is crucial in improving user experiences many virtual reality (VR) and entertainment applications. However, perceptual characteristics of effects remain unexplored to great extent. This paper constructs space that accounts for based on their distances then demonstrates smooth–rough irregular–regular as its two primary dimensions. An authoring constructed with these pairs axes. We also present methods synthesizing new...

In this paper, we report both absolute and differential thresholds for motion in the six cardinal directions as comprehensively possible. As with general 4D effects, used sinusoidal motions low intensity large frequency stimuli. Hence, could also compare effectiveness of types delivering effects. We found that z-axis (up-down) were higher than those x-axis (front-back) y-axis (left-right) kinds type significantly affected thresholds. Further, between reference intensities, a strong linear...

In this paper, we proposed an algorithm for the identification of relieving or worsening current traffic congestion using historic patterns. Historical patterns were placed in adjacency list. The constructed to represent spatial and temporal length status a congested road. Then, found information about historical congestions that similar today's will use show how change future. most pattern among corresponded starting section congestion. One our experiment results had average error when...

This demo is about automatic authoring of various motion effects that are provided with audiovisual content to improve user experiences. Traditionally, have been used for simulators, e.g., flight simulators pilots and astronauts, present physically accurate vestibular feedback. At present, we greatly wider use entertainment purposes, such as 4D rides in amusement parks even shopping malls, films theaters, relative new virtual reality games head-mounted displays personal platforms. However,...

This paper proposes a simulator to generate real tactical moving objects and provide their patterns as well trajectories over time. Due some security standards policies it is not possible collect objects. Considering this problem, in order make experiments related combat management systems we need data set for In the proposed approach, first classify target into three main categories according environment: Air, land water. Secondly, perform generation using an efficient function that...

Complex Event Processing (CEP) over tactical moving objects would detect threats in real time and response defense timely. The input data are stream collected by radar, sonar or other sensors. From the beginning of preprocessing to end threat detection defense, system CEP goes through a series complicated procedures, working based on rules be defined dynamically users. In this paper, we design implement rule-based that allows users insert, update delete rule specifications without code programming.
