    Motivational game design patterns of ’ville games

    The phenomenal growth of social network games in the last five years has left many game designers, game scholars, and long-time game players wondering how these games so effectively engage their audiences. Without a strong understanding of the sources of appeal of social network games, and how they relate to the appeal of past games and other human activities, it has proven difficult to interpret the phenomenon accurately or build upon its successes. In this paper we propose and employ a particular approach to this challenge, analyzing the motivational game design patterns in the popular ‘Ville style of game using the lenses of behavioral economics and behavioral psychology, explaining ways these games engage and retain players. We show how such games employ strategies in central, visible ways that are also present (if perhaps harder to perceive) in games with very different mechanics and audiences. Our conclusions point to lessons for game design, game interpretation, and the design of engaging software of any type

    Procedural Generation of Complex Roundabouts for Autonomous Vehicle Testing

    Full text link
    High-definition roads are an essential component of realistic driving scenario simulation for autonomous vehicle testing. Roundabouts are one of the key road segments that have not been thoroughly investigated. Based on the geometric constraints of the nearby road structure, this work presents a novel method for procedurally building roundabouts. The suggested method can result in roundabout lanes that are not perfectly circular and resemble real-world roundabouts by allowing approaching roadways to be connected to a roundabout at any angle. One can easily incorporate the roundabout in their HD road generation process or use the standalone roundabouts in scenario-based testing of autonomous driving

    Enemy NPC Design Patterns in Shooter Games

    Get PDF
    Gameplay in single-player shooter games primarily consists of combat with Non-player Characters (NPCs). However, there has been little research done to study how enemy NPCs affect player behavior in shooter games. As a consequence, there is no formal language for designers to discuss how NPCs are used in shooter games. This paper presents design patterns for NPCs in shooter games and explores their effects on gameplay. These patterns help designers communicate about and explore new ideas for enemy NPCs and further our understanding about how NPC types can be implemented, enabling more engaging experiences

    SCISAT-1 ACE Mission C&DH Unit Development

    The SCISAT-1 Atmospheric Chemistry Experiment (ACE) Mission is a part of the Canadian Space Agency’s (CSA’s) space science program, to support ongoing research in the areas of solarterrestrial relations, atmospheric sciences and space astronomy. Bristol Aerospace Limited is the CSA’s Spacecraft Prime Contractor for the ACE Mission. The ACE spacecraft will be launched on a Pegasus XL vehicle in mid-2002, co-manifested with a NASA spacecraft. A Control and Data Handling (C&DH) Unit is being developed by Bristol for the ACE Mission. This C&DH Unit will be responsible for all onboard command, control, monitoring and science data recording. This unit is being developed to support a range of Canadian small science missions, from Smallsats to Microsats. The unit is low power and light weight, and features a rad-tolerant core to assure reliable operation in a single string architecture. The C&DH Unit is comprised of a Controller Card (CC), Data Handling Card (DHC), Input/Output Card (IOC) and a Power Supply Card (PSC). Each card is housed in its own aluminum frame, and the frames are integrated into a vertical stack. The unit is expected to operate with 7 Watts orbit average power and uses a UTMC 80C196 16-bit processor running at 16 MHz to manage the satellite operations and perform attitude control. Mass storage of 1.5 Gbytes and CCSDS variable-rate telemetry up to 5 Mbits/sec are provided. This paper will present an overview of the ACE Mission and a description of the C&DH Unit, describing its architecture, hardware/software partitioning, FPGA functionality and key performance specifications

    The rapid developments in technology have brought increased convenience, but at the price of loss of privacy.  Consumers should be aware of the potential threat to their personal information and should learn the facts and take steps to protect themselves.

    Computer-Generated Music for Tabletop Role-Playing Games

    Full text link
    In this paper we present Bardo Composer, a system to generate background music for tabletop role-playing games. Bardo Composer uses a speech recognition system to translate player speech into text, which is classified according to a model of emotion. Bardo Composer then uses Stochastic Bi-Objective Beam Search, a variant of Stochastic Beam Search that we introduce in this paper, with a neural model to generate musical pieces conveying the desired emotion. We performed a user study with 116 participants to evaluate whether people are able to correctly identify the emotion conveyed in the pieces generated by the system. In our study we used pieces generated for Call of the Wild, a Dungeons and Dragons campaign available on YouTube. Our results show that human subjects could correctly identify the emotion of the generated music pieces as accurately as they were able to identify the emotion of pieces written by humans.Comment: To be published in the 16th AAAI Conference ON Artificial Intelligence and Interactive Digital Entertainmen

    Challenges of End-to-End Testing with Selenium WebDriver and How to Face Them: A Survey

    Get PDF
    Proceeding of 2023 IEEE 16th International Conference on Software Testing, Verification and Validation (ICST 2023), 16-20 April 2023, Dublin, Ireland.Modern web applications are complex and used for tasks of primary importance, so their quality must be guaranteed at the highest levels. For this reason, testing techniques (e.g., end-to-end) are required to validate the overall behavior of web applications. One of the most popular tools for testing web applications is Selenium WebDriver. Selenium WebDriver automates the browser to mimic real user actions on the web.While Selenium has made testing easier for many Teams worldwide, it still has its share of challenges. To better understand the challenges and the corresponding solutions adopted we decided to undertake a personal opinion survey from the industry (in total with 78 highly skilled participants) with a focus on the Selenium ecosystem.The results allow understanding which challenges are consid-ered more relevant by professionals in their daily practice and which are the techniques, approaches, and tools they adopt to face them. Therefore, this study is useful to (1) practitioners interested in understanding how to solve the problems they face every day and (2) researchers interested in proposing innovative solutions to problems having a solid industrial impact.This work was partially supported in part by the Ministerio de Ciencia e Innovación-Agencia Estatal de Investigación (10.13039/501100011033) through the H2O Learn project under Grant PID2020-112584RB-C31, and in part by the Madrid Regional Government through the e-Madrid-CM Project under Grant S2018/TCS-4307
