Volcano: An interactive sword generator

In this work, we introduce Volcano, a tool for the procedural generation of 3D models of swords. Unlike common procedural content generation tools, it exploits interactive evolution to reduce as much as possible the effort of the users during the generation process. Indeed, Volcano allows to forge the desired type of swords through a rather simple visual exploration of the design space. The 3D models generated with the tool can be directly used as game assets or further developed with a standard modeling software. A prototype of Volcano was tested by 30 users, including both students and game developers. The feedbacks received are very positive: tools like Volcano might be useful both for players, to create user contents, and for developers, to speed-up the design of game contents

An intelligent game engine for the at-home rehabilitation of stroke patients

The recent availability of advanced video game interfaces (such as the Microsoft Kinect, the Nintendo WiiMote and Balance Board) is creating interesting opportunities to provide low-cost rehabilitation at-home for patients. In this context, video games are rising as promising tools to guide patients through their recovery experience and to increase their motivation throughout the rehabilitation path. However, to be applied to clinical scenarios, video games must be designed to adhere to the clinical requirements and to meet doctors/patients expectations. They also need to be integrated within multi-level platforms that can allow different levels of monitoring, e.g., at a personal level by the therapist, at the hospital level by the doctors, and at the regional level by the government agencies. In this paper, we overview an intelligent game engine for the at-home rehabilitation of stroke patients The engine provides several games that implement actual rehabilitation exercises and have been developed in strict collaboration with therapists. It is integrated in a patient station that provides several types of monitoring and feedback using virtual and/ or human therapists

The design of a comprehensive game engine for rehabilitation

Physical and cognitive rehabilitation under the form of therapeutic videogames has been growing in popularity over the last years. Many rehabilitation games (or exergames) have been created with the intent to promote functional rehabilitation in a highly motivational environment. However, such exergames are often created as standalone products typically designed to target a specific exercise. Accordingly, they are usually difficult to integrate in a more structured therapy and also have very different and varied features. There is therefore a need in this area for a more holistic approach with game engines specifically designed for rehabilitation that would represent the next step in this field to guarantee efficacy, accessibility and motivational factors of exergames. In this paper, we present our Intelligent Game Engine for Rehabilitation (IGER) that tries to address these issues; we highlight the features it supports, we present some of the games we created with it, and the initial results we achieved so far

IGER: A Game Engine Specifically Tailored to Rehabilitation

Exergames for rehabilitation, both in the physical and cognitive fields, have been the target of much research in the last years. Such exergames, however, are often created for a specific impairment and cannot be generalized to other domains. More generally speaking, the lack of shared design and development guidelines for rehabilitation games can be highlighted. The Intelligent Game Engine for Rehabilitation (IGER) described here has been developed with the intent to provide a framework for building rehabilitation exergames that are functional, accessible and entertaining. Several features, mandatory for rehabilitation, have been incorporated: configuration, adaptation, monitoring, data logging and feedback through a virtual therapist. Besides describing how these features have been implemented in IGER, we describe here also a few games we created with it and their rationale

IGER: An Intelligent Game Engine for Rehabilitation

We present here a novel game engine, designed specifically to guide rehabilitation at home. Besides the classical functionalities: animation, rendering, collision detection and so forth, adaptation to the patient status and monitoring are embedded inside the engine. Moreover, a virtual therapist is also provided that can advice and support the patient throughout the rehabilitation sessions. Some game examples built on this engine are described

Exergaming and rehabilitation: A methodology for the design of effective and safe therapeutic exergames

We present here a comprehensive definition of therapeutic exergames from which a methodology to create safe exergames for real therapy pathways is derived. Three main steps are identified. (I) A clear identification of all the exercise requirements, not only in terms of goals of the therapy, but also in terms of additional constraints. Characteristic parameters for determining the challenge level and to assess progression are also defined in this phase. (II) The exercise is transformed into a Virtual Exercise, in which all the exercise elements are implemented inside a simple virtual environment. In this step the discussion between clinical and ICT teams allows maximizing the effectiveness of exergames implementation. (III) The final exergame is realized by introducing on top of the exercise all the game elements suggested by good game design to maximize entertainment. A clear line between exercises and games is drawn here. We illustrate the methodology with exergames designed for (1) balance and posture and (2) neglect rehabilitation, implemented and tested with post-stroke patients training autonomously at home. The methodology can have a broader impact as it can be applied also in other gaming fields in which the requirements go beyond entertainment

Intelligent Game Engine for Rehabilitation (IGER)

Computer games are a promising tool to support intensive rehabilitation. However, at present, they do not incorporate the supervision provided by a real therapist and do not allow safe and effective use at a patient's home. We show how specifically tailored computational intelligence based techniques allow extending exergames with functionalities that make rehabilitation at home effective and safe. The main function is in monitoring the correctness of motion, which is fundamental in avoiding developing wrong motion patterns, making rehabilitation more harmful than effective. Fuzzy systems enable us to capture the knowledge of the therapist and to provide real-time feedback of the patient's motion quality with a novel informative color coding applied to the patient's avatar. This feedback is complemented with a therapist avatar that, in extreme cases, explains the correct way to carry out the movements required by the exergames. The avatar also welcomes the patient and summarizes the therapy results to him/her. Text to speech and simple animation improve the engagement. Another important element is adaptation. Only the proper level of challenge exercises can be both effective and safe. For this reason exergames can be fully configured by therapists in terms of speed, range of motion, or accuracy. These parameters are then tuned during exercise to the patient's performance through a Bayesian framework that also takes into account input from the therapist. A log of all the interaction data is stored for clinicians to assess and tune the therapy, and to advise patients. All this functionality has been added to a classical game engine that is extended to embody a virtual therapist aimed at supervising the motion, which is the final goal of the exergames for rehabilitation. This approach can be of broad interest in the serious games domain. Preliminary results with patients and therapists suggest that the approach can maintain a proper challenge level while keeping the patient motivated, safe, and supervised

Self-adaptive games for rehabilitation at home

Computer games are a promising tool to support rehabilitation at home. It is widely recognized that rehabilitation games should (i) be nicely integrated in generalpurpose rehabilitation stations, (ii) adhere to the constraints posed by the clinical protocols, (iii) involve movements that are functional to reach the rehabilitation goal, and (iv) adapt to the patients\u2019 current status and progress. However, the vast majority of existing rehabilitation games are stand-alone applications (not integrated in a patient station), that rarely adapt to the patients\u2019 condition. In this paper, we present the first prototype of the patient rehabilitation station we developed that integrates video games for rehabilitation with methods of computational intelligence both for on-line monitoring the movements execution during the games and for adapting the gameplay to the patients\u2019 status. The station employs a fuzzy system to monitor the exercises execution, on-line, according to the clinical constraints defined by the therapist at configuration time, and to provide direct feedback to the patients. At the same time, it applies real-time adaptation (using the Quest Bayesian adaptive approach) to modify the game play according both (i) to the patient current performance and progress and (ii) to the exercises plan specified by the therapist. Finally, we present one of the games available in our patient stations (designed in tight cooperation with therapists) that integrates monitoring functionalities with in-game self-adaptation to provide the best support possible to patients during their routine
