Augmented Reality based Mobile Application for Energy Monitoring and IoT Device Control

IoT has become an integrated part of our lives changing ways in which we operate our everyday appliances. In addition to making our home appliances smart, it has become a common trend for companies to adopt industry 4.0, which uses various sensors to monitor the equipment, machinery, and the work environment. We often come across multiple brands which make smart appliances but each brand comes with its separate mobile application for the appliance's operation. This requires us to switch between Apps to control these appliances if we at all remember which App controls which appliance. We intend to solve these two major inconveniences by creating a single mobile application that can control all these appliances using Augmented Reality technology. All we have to do is point our camera at the appliance that we need to operate and the App will display control options in real-time AR. This paper produces five important contributions: 1) An AR-based mobile application to control IoT devices and monitor the environment. 2) Implementing the mobile application using Unity 3D engine and Vuforia SDK. 3) Integrating a commercially available IoT device with the mobile application. 4) Integrating custom-made hardware IoT device with mobile application. 5) Integrating this combination to make our industries and homes smarter Keywords:

Effect of visual elements on Indoor soundscape perception in open-plan office

This study examined the effect of changes in visual elements on spatial comfort and work productivity in the aspect of indoor soundscape perception in the open-plan office (OPO) sound environment. Various OPO visual stimuli were simulated using computer software (Unity 3D engine) to change the visual environment by varying variables such as worker density, window ratio, green ratio, and ceiling height. An interactive virtual reality environment was implemented to perform a specific task while experiencing the audio-visual stimuli combining the general OPO noise stimulus and the simulated OPO visual stimulus. Subjective evaluation was performed on a total of 30 subjects to evaluate indoor soundscape quality and work performance for each stimulus. Based on the results of this study, a pleasant OPO design guideline was proposed. Keywords: Open-plan office, indoor soundscape, interactive VR test, spatial comfort

The Application of Intelligent Algorithms in the Animation Design of 3D Graphics Engines

With the rapid improvement of computer hardware capabilities and the reduction of cost, the quality of game pictures has made a qualitative breakthrough, which has reached or exceeded the picture effect of many dedicated virtual reality engines. On the basis of the design and implementation of the virtual reality 3D engine, the rendering queue management method is proposed to improve the frame rate. Based on the object-oriented design method, emitter regulator particle rendering mode, and traditional bone skin animation technology, the key structure technology in skeletal animation is analyzed, and the animation controller used to control animation playback and key structure interpolation operation is designed, which achieves the ideal animation effect. Finally, a prototype system based on engine is implemented.

Demonstration of a Virtual Reality Driving Simulation Platform

A virtual reality (VR) driving simulation platform has been built for use in addressing multiple research interests. This platform is a VR 3D engine (Unity © ) that provides an immersive driving experience viewed in an HTC Vive © head-mounted display (HMD). To test this platform, we designed a virtual driving scenario based on a real tunnel used by Törnros to perform onroad tests [1] . Data from the platform, including driving speed and lateral lane position, was compared the published on-road tests. The correspondence between the driving simulation and onroad tests is assessed to demonstrate the ability of our platform as a research tool. In addition, the drivers’ eye movement data, such as 3D gaze point of regard (POR), will be collected during the test with an Tobii © eye-tracker integrated in the HMD. The data set will be analyzed offline and examined for correlations with driving behaviors in future study.

The development of Virtual Reality technology is currently being developed even in every field of science, one of which is room mapping. Mapping digital space as a visualization medium has helped provide detailed information through the use of three-dimensional (3D) technology. To build a visualization of the room that is useful for the community, especially in the area of ​​the hospital environment, especially hospital patients so that in fighting the disease patients remain in a state of enthusiasm, safe, comfortable and conducive supported by the environment. With the use of 3D technology, in building an interactive room design VR-Room Patient using the Unity 3D Engine is expected to help patients in choosing treatment rooms for Inpatient Hospital. The planned room description is the Presidential Suite Room, Deluxe Suite, Junior Suite and Class II. The results of this study in the form of visualization illustrated by each area, while the evaluation of the results of this study was conducted by asking respondents to fill in an assessment questionnaire on VR visualization using usability testing using the usability heuristic approach, and the usability test results obtained with an average value of 3.194 taken from the assessment of respondents on a scale of 1 to 4 where this explains that the VR-Room Patient application has a good level of reusability ie the average value is above 3.

Pocket Skate: Prototype of A Mobile Projection-Based Game

Introduction: Exergaming is the activity in which this kind of videogame relies on the technology from the body’s movement or reaction. There are several existing commercial devices that has been used as user interface for an exergaming activity such XBOX Kinnect and Nintendo Wii Fit. However, these games platform are quite expensive and considered as luxury as they are a dedicated device only for games. What we propose here a different kind of exergaming, that is by using a typical mobile phone as the censor/controller and combined it with a display device such as a smart TV or a laptop. Methods: We use prototyping model that involve “communication”, where the problem and/or room for improvement is being identified, then “quick plan”, where various information are being analyzed and all the required components are being recorded and verified, and then “quick design”, where the app design be created, and then “prototype construction” when we create the app, and lastly “deployment and feedback” where we tried the app and check for faults. The cycle repeats for fixing any things that did not work. Results: The researcher was able to construct a proof of concept prototype of the app. First, the player will look the hero, a skater, on smart TV or other wireless projection where will be receive mirror feeds from the smartphone. The smartphone itself was placed on the player hips and to control the skater and user must make a small jump to make the skater jump or face side to side to make the skater change direction. Discussion: While the app is still a prototype, yet it was able to show how a game can use a projected-based interface and mixed it the use of gyroscope and accelerometer censors. Future recommendation would be integrating it with calories counters for it to be fully “exergaming”. Keywords: exergaming, gyroscope, accelerometer, virtual reality, Unity 3D Engine
