Application of augmented reality and robotic technology in broadcasting: A survey

As an innovation technique, Augmented Reality (AR) has been gradually deployed in the broadcast, videography and cinematography industries. Virtual graphics generated by AR are dynamic and overlap on the surface of the environment so that the original appearance can be greatly enhanced in comparison with traditional broadcasting. In addition, AR enables broadcasters to interact with augmented virtual 3D models on a broadcasting scene in order to enhance the performance of broadcasting. Recently, advanced robotic technologies have been deployed in a camera shooting system to create a robotic cameraman so that the performance of AR broadcasting could be further improved, which is highlighted in the paper

Development of computer vision algorithms using J2ME for mobile phone applications.

This thesis describes research on the use of Java to develop cross-platform computer vision applications for mobile phones with integrated cameras. The particular area of research that we are interested in is Mobile Augmented Reality (AR). Currently there is no computer vision library which can be used for mobile Augmented Reality using the J2ME platform. This thesis introduces the structure of our J2ME computer vision library and describes the implementation of algorithms in our library. We also present several sample applications on J2ME enabled mobile phones and report on experiments conducted to evaluate the compatibility, portability and efficiency of the implemented algorithms

Marker-Based Embodied Interaction for Handheld Augmented Reality Games

This article deals with embodied user interfaces for handheld augmented reality games, which consist of both physical and virtual components. We have developed a number of spatial interaction techniques that optically capture the device's movement and orientation relative to a visual marker. Such physical interactions in 3-D space enable manipulative control of mobile games. In addition to acting as a physical controller that recognizes multiple game-dependent gestures, the mobile device augments the camera view with graphical overlays. We describe three game prototypes that use ubiquitous product packaging and other passive media as backgrounds for handheld augmentation. The prototypes can be realized on widely available off-the-shelf hardware and require only minimal setup and infrastructure support

Marker-Based Embodied Interaction for Handheld Augmented Reality Games

Abstract This paper proposes embodied and manipulative interaction for handheld augmented reality games. We use camera-equipped mobile devices and marker-based interaction as a means for gesture-based control of games that incorporate physical and virtual aspects. In addition to being a controller that recognizes multiple game-dependent gestures, the mobile device displays the camera image and augments it with graphical overlays. The overlays are registered with objects and areas in the camera image. We have developed marker-based interaction techniques that capture the posture and movement of a device relative to a marker and thus enable manipulative control. We describe game prototypes that use ubiquitous product packaging and other passive media as backgrounds for handheld augmented reality games.

Development of augmented reality software and QR codes for the academic support of students in the fifth grade of primary school in the mathematical subject

En su informe sobre el avance en los objetivos del milenio fijados por los países inscritos por la ONU, se evidencia la gran brecha que existe entre instituciones urbanas y rurales, al no contar con recursos económicos, tecnológicos y oportunidades como el acceso a contenidos virtuales por medio de internet. Por este motivo surge la necesidad de desarrollar una aplicación que permita y apoye el proceso de enseñanza de los estudiantes combinando la tecnología realidad aumentada, apoyada por un tipo de código de barras QR que cuente no solo con las mismas características de los marcadores tradicionales, sino que pueda almacenar información y ser identificado desde cualquier sentido por la aplicación. Este documento presenta la evolución de la realidad aumentada, la metodología y los resultados obtenidos a través del estudio comparativo de los códigos de barras bidimensionales más usados; el proceso del desarrollo del software y su aplicación en un grupo experimental con el propósito de conocer el grado de aceptación de los estudiantes hacia este tipo de aplicaciones, dejando un propuesta y vistazo sobre la importancia de esta aplicación como herramienta educativa.INTRODUCCIÓN 7 1.

Analyzing the Impact of Spatio-Temporal Sensor Resolution on Player Experience in Augmented Reality Games

Along with automating everyday tasks of human life, smartphones have become one of the most popular devices to play video games on due to their interactivity. Smartphones are embedded with various sensors which enhance their ability to adopt new new interaction techniques for video games. These integrated sen- sors, such as motion sensors or location sensors, make the device able to adopt new interaction techniques that enhance usability. However, despite their mobility and embedded sensor capacity, smartphones are limited in processing power and display area compared to desktop computer consoles. When it comes to evaluat- ing Player Experience (PX), players might not have as compelling an experience because the rich graphics environments that a desktop computer can provide are absent on a smartphone. A plausible alternative in this regard can be substituting the virtual game world with a real world game board, perceived through the device camera by rendering the digital artifacts over the camera view. This technology is widely known as Augmented Reality (AR). Smartphone sensors (e.g. GPS, accelerometer, gyro-meter, compass) have enhanced the capability for deploying Augmented Reality technology. AR has been applied to a large number of smartphone games including shooters, casual games, or puzzles. Because AR play environments are viewed through the camera, rendering the digital artifacts consistently and accurately is crucial because the digital characters need to move with respect to sensed orientation, then the accelerometer and gyroscope need to provide su ciently accurate and precise readings to make the game playable. In particular, determining the pose of the camera in space is vital as the appropriate angle to view the rendered digital characters are determined by the pose of the camera. This defines how well the players will be able interact with the digital game characters. Depending in the Quality of Service (QoS) of these sensors, the Player Experience (PX) may vary as the rendering of digital characters are affected by noisy sensors causing a loss of registration. Confronting such problem while developing AR games is di cult in general as it requires creating wide variety of game types, narratives, input modalities as well as user-testing. Moreover, current AR games developers do not have any specific guidelines for developing AR games, and concrete guidelines outlining the tradeoffs between QoS and PX for different genres and interaction techniques are required. My dissertation provides a complete view (a taxonomy) of the spatio-temporal sensor resolution depen- dency of the existing AR games. Four user experiments have been conducted and one experiment is proposed to validate the taxonomy and demonstrate the differential impact of sensor noise on gameplay of different genres of AR games in different aspect of PX. This analysis is performed in the context of a novel instru- mentation technology, which allows the controlled manipulation of QoS on position and orientation sensors. The experimental outcome demonstrated how the QoS of input sensor noise impacts the PX differently while playing AR game of different genre and the key elements creating this differential impact are - the input modality, narrative and game mechanics. Later, concrete guidelines are derived to regulate the sensor QoS as complete set of instructions to develop different genres or AR games
