Your Way Your Missions: A Location-Aware Pervasive Game Exploiting the Routes of Players

With the development of pervasive computing, location-aware pervasive games have proliferated quickly. To counter the inefficiency of information adaptation based on a location and a radius, this article presents the design and implementation of Your Way Your Missions (YWYM), which is a location-aware pervasive game exploiting the routes of players. YWYM provides a Google Maps–based tool for players to predefine routes, and utilizes self-reporting method to obtain the planned routes of players. By such a design, missions are returned to players in terms of the location properties of missions and the planned routes of players. A field study was conducted to investigate the usage of YWYM, and the results indicate that route predefining and self-reporting methods are an effective approach to obtain the planned routes of players, and information adaptation based on the planned routes of players could help them find missions at any place and any time.     

Pervasive Computing Helps Fans Get Into the Game

Pervasive computing devices give fans more control over their experience and more information about the games they love, even when they're miles away. Mobile devices have put sports into the pocket of the fan. Mobile content and messaging deals let consumers access their sports when and where they want to. Prior to the use of the wireless caddie, the application provider, set up a Wi-Fi network around each course. with the new devices, the existing network offers more ubiquitous coverage with less set-up time. Extraction relies on an image-processing technique that can pull out information and decode the barcodes. According to IBM, when this system is in place, any mobile device can be used with a blacklight-LED-enabled camera as the reader.     

Modeling and Rendering of the Atmosphere Using Mie-Scattering

This paper presents a method for rendering of the atmosphere by means of Mie-scattering. The method is based on a concentric atmospheric model, which is divided into four submodels: for clear air, aerosol, ozone, and rain. In order to simulate and visualize the various atmospheric effects, each of these submodels can be parameterized by the user as desired. The process of rendering an outdoor scene requires an enormous amount of computing power. In order to make this method suitable for efficient implementation, some simplifications and approximations are discussed. In addition, a selection of the rendering results are presented, and our further activities in the field of atmospheric rendering are discussed.

Educating the Next Generation of Mobile Game Developers

Mobile gaming is one of the fastest growing segments in the video game industry. Through a partnership between Motorola Laboratories and GamePipe Laboratory at the University of Southern California, we are exploring Linux's capabilities for mobile gaming and to provide developers with an alternative to what is predominantly a Java-based medium. Moving beyond Java lets game developers fully leverage the hardware advances and software capabilities of high-end smart phones

Influence of Vibration Modes and Human Operator on the Stability of Haptic Rendering

Developing stable controllers, which are able to display virtual objects with high stiffness, is a persistent challenge in the field of haptics. This paper addresses the effect of internal vibration modes and the human operator on the maximum achievable virtual stiffness. An 11-parameter mechanical model is used to adequately characterize the overall system dynamics. Experiments that are carried out on LHIfAM and PHANToM haptic interfaces demonstrate the importance of vibration modes to determine the critical stiffness when the user grasps the device.      

Image Space Rendering of Point Clouds Using the HPR Operator

The hidden point removal (HPR) operator introduced by Katz et al. [KTB07] provides an elegant solution for the problem of estimating the visibility of points in point samplings of surfaces. Since the method requires computing the three‐dimensional convex hull of a set with the same cardinality as the original cloud, the method has been largely viewed as impractical for real‐time rendering of medium to large clouds. In this paper we examine how the HPR operator can be used more efficiently by combining several image space techniques, including an approximate convex hull algorithm, cloud sampling, and GPU programming. Experiments show that this combination permits faster renderings without overly compromising the accuracy.     

The Cooperative Work of Gaming: Orchestrating a Mobile SMS Game

This paper focuses on orchestration work in the first iteration of a mobile game called Day Of The Figurines, which explores the potential to exploit text messaging as a means of creating an engaging gaming experience. By focusing on orchestration we are especially concerned with the ‘cooperative work that makes the game work’. While the assemblage or family of orchestration practices uncovered by our ethnographic study are specific to the game – including the ways in which behind the scenes staff make sense of messages, craft appropriate responses, and manage and track the production of gameplay narratives as the game unfolds – orchestration work is of general significance to our understanding of new gaming experiences. The focus on orchestration work reveals that behind the scenes staff are co-producers of the game and that the playing of games is, therefore, inseparably intertwined with their orchestration. Furthermore, orchestration work is ‘ordinary’ work that relies upon the taken for granted skills and competences of behind the scenes staff; ‘operators’ and ‘authors’ in this case. While we remain focused on the specifics of this game, explication of the ordinary work of orchestration highlights challenges and opportunities for the continued development of gaming experiences more generally. Indeed, understanding the specificities of orchestration work might be said to be a key ingredient of future development.

Disaster Warnings in Your Pocket: How Audiences Interpret Mobile Alerts for an Unfamiliar Hazard

This study investigates how people interpret Wireless Emergency Alerts (WEAs) and Twitter‐length messages (‘tweets’) delivered over mobile devices for an unfamiliar hazard. Specifically, through four (N = 31) focus groups and 31 think‐out‐loud interviews, participants’ understanding of, belief in and personalisation of WEAs and tweets were assessed for a mock improvised nuclear device detonation in a major U.S. metropolitan area. While participants offered a wide variety of interpretations, WEAs and tweets were often deemed confusing, difficult to believe and impersonal. Participants also consistently found WEAs and tweets to be fear inducing and uninformative. The findings compel improvements in the way that WEAs and tweets are currently written, as well as indicate future directions for applied risk and crisis communication theory development.
