Virtual reality applications in manufacturing system

Nur Suraya Sahol Hamid; Faieza Abdul Aziz; Amir Azizi

Virtual reality (VR) is a high-end human computer interface that strives to immerse the designers and users completely in a virtual interactive environment for a simulation of real world. In order to meet the requirements of market competition, VR technologies can not only reduce effectively the time and cost, but also optimize complex products in the design process. Virtual reality is a rapidly developing computer interface that strives to immerse the user completely within an experimental simulation, thereby enhancing the overall impact and providing a much more intuitive link between the computer and the human participants. Virtual reality has been applied successfully to hundreds of scenarios in diverse areas including prototyping, manufacturing, scientific visualisation, engineering, and education. This paper discusses the applications of virtual reality in the manufacturing industry.

Simulation of "time-based" versus "sensor-based" traffic light system

Abdul-Yasser Abd-Fatah; Rosnah Mohd Yusuff; Faieza Abdul Aziz; Norzima Zulkifli

Simulation of time-based and sensor-based traffic light control system at four-way intersection using Arena simulation software was studied. Introduction of sensors in traffic light system has been developed to reduce waiting time of vehicles at intersection. Simulation with Arena is done to observe if the improvement of sensor-based system is significant over the current system (fixed-time) and to evaluate the effects of implementing sensor-based system in busy and normal road condition. Algorithm of traffic light sequence is done first prior to development of simulation. Then, the simulation of traffic light system is developed for both normal and busy traffic condition and the data obtained is analyzed using statistical process control. From the result, average waiting time for sensor-based system was 62.5% less than time-based system for each vehicle in the normal traffic condition, and 15% less for busy traffic condition. This shows significant improvement based on the paired T-test done.

Taravatsadat Nehzati; Napsiah Ismail; Faieza Abdul Aziz; Seyed Ali Hosseini

This paper presents a research project carry out at Faculty of Engineering, University Putra Malaysia in the area of fuzzy scheduling. The fuzzy based scheduling model, in this paper, will only deal with the job assignment problem in Reconfigurable Manufacturing System (RMS). The model will select the best alternative machine with multi-criteria scheduling through an approach based on a fuzzy logic. This paper aim to show the framework of research and methodology, which aspire to be constructing based on.

Particle Reduction at Metal Deposition Process in Wafer Fabrication

Faieza Abdul Aziz; Izham Hazizi Ahmad; Norzima Zulkifli; Rosnah Mohd Yusuff

Metal Deposition or metallization process is one of the processes in fabricating a wafer. A wafer is a thin slice of semiconductor material, such as a silicon crystal, used in the fabrication of integrated circuits and other micro-devices. Due to the nature on the process, it creates lot of particles, which would impact the next process if it were not removed. Particle deposition on the wafer surface can cause the circuit to malfunction; leading to a loss of yield. Cleaning process needs to be done after metal deposition process in order to remove the particles

Virtual Reality Framework Development in Malaysian Automotive Manufacturing Industry

Maryam Mousavi; Faieza Abdul Aziz; Napsiah Ismail; Shahryar Sorooshian

Virtual reality (VR) provides a new opportunity to improve productivity and enhance quality of manufacturing. Malaysian automotive industry also adopted VR and three-dimensional (3D) modelling at different stages. It is always difficult to choose the right technology at the right time and at the right place. There is no clear guideline among automotive companies about technological causes behind their success and failure. Most of the time, automotive industry is confused to decide which technology is most appropriate for their technology-based industrialisation and improvement. Six car companies in Malaysia have been chosen for this study. Forty questionnaires were randomly distributed at each company. More than 62% of the questionnaires received from the respondents. To analyse respondents’ answers, t-Test and Pearson chi-square test were conducted followed by frequency analysis and a conceptual method has also been used for developing a framework. This research provides a framework for automotive industry adoption with VR technology. This framework recommends the VR technology adoption to the industry based on its remarkable points in each segments of the industry. The framework will help policy makers, managers, designers, engineers, and researchers to make their decision more easily and efficiently for VR technology implementation. Results of framework implementation have also been described in the results section of the paper.

A study on real-time auditory feedback technique in manipulation task

Lai Jian Ming; Faieza Abdul Aziz; Barkawi Sahari

The material presented in this project has illustrated that auditory interfaces are versatile and efficient means of establishing a communication between a computer system and the user. Listening is perhaps the communication channel with the highest bandwidth after visual perception, and certainly a channel whose characteristics are so different from visual perception.

Real-Time Visual Feedback Enhances Tower of Hanoi Manipulation Task

Faieza Abdul Aziz; On Chee Leong

This paper investigates the effect of real-time visual feedback to enhance user performance in manipulation of 3 discs “Tower Of Hanoi” task by using Microsoft Visual C++ and OpenGL as a graphic library. This study measures the effectiveness of time taken to complete the task between simulation with real-time visual feedback and without feedback. To do this, a group of respondent have been chosen and tested on the “Tower of Hanoi” manipulation task, in which they received real-time visual feedback and without feedback. Result for time to complete the task has been plotted and analyzed. This work also evaluates the best method of real-time visual feedback in simulation task. Respondents have been given different type of visual feedback such as “colour” or “text” feedback and the time to complete the task has been plotted and analyzed. Three different methods have been investigated and the results showed that the shortest time taken to complete the task was obtained through the experiment with text feedback method while the minimum average number of steps to solve the Tower of Hanoi was also achieved via text feedback method.

Utilising Virtual Environments To Research Ways To Improve Manipulation Task

Faieza Abdul Aziz; On Chee Leong; Lai Jian Ming

Real-time feedback systems has been widely used and become very important in many fields. In this project Microsoft Visual C++ together with OpenGL programming software were employed to create a Tower of Hanoi which was used as the experiment task. The realtime system has been studied by adding a real-time visual feedback into a simulation task. Two types of real-time visual feedback were discussed in this work, which were colour feedback and text feedback. Visual feedback techniques were design to give the cues to the users about the reasons for errors occurrence. Four different methods were compared and contrasted which are no feedback, with feedback, with text feedback and with colour feedback. The Tower of Hanoi is also programmed to provide different feedback in real time for the purpose of investigating the effect of auditory feedback to the user. Moreover, the Tower of Hanoi is programmed in stereoscopic for virtual reality manipulation task. Three types of feedback were evaluated. It consists of non-speech, speech auditory feedback and without feedback. The goals of this study were to explore real-time visual feedback technique and compare the effectiveness of different types of real-time visual feedback technique. For the purpose of investigating the effect of auditory feedback to the user, the result of the project showed the participant performance in solving the Tower of Hanoi is better in the non-speech auditory feedback. Beside that, speech auditory feedback provides greatest understanding to the user throughout the experiment, but the drawback is the participant cannot complete the task in shorter time.
