Path Planning for Two-Link Navigation in an Unknown Environment using webcam

In this article, we used image processing by a webcam connected on top of the arm robot. The robot navigation is in an unknown environment. Then start point and target point were determined for the robot, so the robot needs to have a program for path planning using Voronoi diagrams to find the path. After the possible path for moving the robot was found, the route information obtained was sent to the arm robot. The arm robot moves in the workspace and any time new information was processed via the webcam. The program was written using MATLAB software which at controls the robot’s movement the unknown environment

Co-creation Tourism Experience in Perceived Usability of Interactive Multimedia Features on Mobile Travel Application

The aim of this paper is to explore the use of interactive multimedia features on mobile travel services to improve touristic experiences. This study delivered a workable prototype with visiting Sarawak as a case study by integrating locality/authenticity design and interactive multimedia features content. User-testing was carried out to identify whether the mobile application usability can improve visitor experiences. A total of 40 visitors (18 male and 22 female) were recruited to participate in the user-testing study. The results indicated a positive SUS score 81 out of 100 and that multimedia interactivity on mobile travel application could enrich tourist’s co-creation experiences compared to just static navigation and limited interaction. The outcome also significantly enhanced tourism experiences through authenticity design attractions such as iconicity and heritage elements value of a destination region. Overall, the findings provide perception of how tourists perceived usability of interactive mobile travel application and the impact of interface motif. Implications and suggestion are further discussed in this paper

An Investigation on the Usability of Mobile Travel Guide Application: A Comparison Study

The sophistication of interactive travel guide mobile application technologies has increased rapidly over the years. A dynamic travel app-user interaction during traveling is an important part of user experience (UX). However, in regular travel application settings, essential user interface (UI) design for easy navigation can be a challenged for some user. In this paper, a study of three different travel guide applications available on the market was carefully chosen to further experiment and measure the user experience through System Usability Scale (SUS). The method of 1-Way Within Subjects ANOVA (or repeated measure design) was conducted to determine the significant differences between the three travel guide applications design on a sample size of 30 participants. Findings show that there was a significant effect of travel guide type, with reading of Wilks’ Lambda = 0.35, F(2,28) = 25.23, p = 0.00. Hence, Paired Samples T -Tests were conducted to compare the three post hoc tests. Results indicated that interface design type does have an effect on user experience. Consequently, the application with the most familiar function and the simplest, straight forward visual display were thought to be the most effective, efficient, and satisfied from participants

Integrating Interactive Multimedia Objects in Mobile Augmented Reality for Sarawak Tourism

Augmented Reality (AR) is a form of technology that superimpose virtual object or content in a real-world environment to create a mixture of reality. This research studies ARToolKitPlus tracking and developed an Android based AR system which integrate mobile graphics and interaction modules, such as audio, video and 3D objects. The development of multimedia based mobile AR system involved video capturing, image processing, mobile graphics and interactive multimedia features. Android camera Application Programming Interface (API) was implemented for video capturing purposes. In order to perform image processing tasks, an image library was built such as greyscale transformation and thresholding. The graphics module for this system was built using OpenGLES and PowerVR graphics API. Whereas, audio and video API for Android platform were used to build multimedia based audio and video module. As for interaction module, technique of color picking algorithm was applied. Henceforth, a prototype of mobile Sarawak Tourism system was developed to evaluate the multimedia based modules functionalities testing; text, animations, audio, video, 2D/3D object interactions. A preliminary survey was conducted to measure the interaction performance and usability of multimedia based modules AR on Sarawak Tourism application

Interactive based secured online organizational culture audit system

Organization culture represents the set of values, beliefs, underlying assumptions, expectations and norms that define how employees think, decide and perform. The focal issue associated with organizational culture is its association with organizational performance. This proposed online organizational culture audit system should be further secured using a facial recognition element where the system could recognize the human face using the camera and only then allows the authorize user to operate the system. The system will be developed using the Human Factors and Human Computer Interactions (HCI) approach to ensure usability and user friendliness of user when interacting with the system. The combination of recognition and interactions in augmented way will give birth to a new type of system that conforms to Human Factors need and provides user with a new computing experience that contains text and graphical information

Objects tracking from natural features in mobile augmented reality

Real world objects are recognized by tracking less and tracking based techniques. Mobile augmented reality browsers are tracking less systems, which acquires location data using global positioning system and provide information in the form of maps or web links. Tracking based techniques recognize objects through markers or directly real world objects without markers. Marker based systems actually track the markers not the real objects and therefore, these approaches hides the reality. Markerless (direct real object tracking) systems use client-server architecture. However, these are affected by network latency. The Smartphone is capable to recognize and track real world objects without any server and marker. It can guide the users about their location and also provide information in a convenient way. Therefore, an improved algorithm for tracking real world objects through natural features was formulated. The modified version of speed up robust features (SURF) was used for features extraction from live mobile camera image and recognition. The pose matrix from extracted features was calculated by Homography. The adapted algorithm was tested in a mobile AR-prototype application using iPhone. It was found from the results that the formulated algorithm recognized and tracked the real world objects from natural features in speedy, easy and convenient wa

Graphics, Audio-visuals and Interaction (GAI) based Handheld Augmented Reality System

Augmented Reality is considered as one of the highly sophisticated technologies in research field of virtual reality. It generates the virtual information to the real world to the user's perception and interaction to perform the tasks. Graphics, Audio-visual and Interaction (GAI) based mobile Augmented Reality is a Human Computer Interaction technology where user can view the multimedia content (like video, 2D, 3D, text, animation) with audio visuals in augmented environment. GAI based mobile AR system allows user to develop their own Augmented Reality applications and games. This system based on Symbian and Android Smartphone where the users can use their Smartphone's camera for real time video capturing and rendering virtual object augmented environments. Users can interact and control the virtual objects by touch in touch enable phone or by button in non touch phone. The general purpose of this technology is to introduce multimedia base Mobile Augmented Reality to user. This paper describes the potential of AR in mobiles and how the various useful features like 2D/3D object, audio, video can be implemented in Mobile AR
