一种用于图形设备接口的笔画模型方法

视频监控的在屏交互过程中,需要快速地对交互控件、感兴趣区域、活动标记等图形和图像进行绘制,为避免画面的停滞感,要求图形设备接口能快速进行绘制.为此,提出了一种笔画模型方法.利用 DirectX的原始绘制能力,该方法将绘制任务转换成笔画对象,使视频系统在实时运行过程中,只需将已转换的笔画对象的绘制数据提交给 DirectX 进行渲染和显示即可,降低重复绘制时间,满足系统的快速绘制要求.基于笔画模型方法,开发了一种可快速绘制的图形设备接口.

认知语言康复系统的设计与实现

随着现代医学技术的飞速发展,脑卒中患者的死亡率相对下降,但脑卒中以其高致残率的特点,仍然是困扰我国医护人员跟患者的难题。针对我国认知语言障碍患者特点,结合MoCA(Montreal Cognitive Assessment蒙特利尔认知评估量表)、MMSE(mini-mental state examination简易智能精神状态检查量表)、NCSE(Neurobehavioral Cognitive Status Examination神经行为认知状况测试)等认知评定量表,设计了一套集数据管理分析及训练为一体的认知语言功能康复软件系统。该系统的研发和应用以虚拟环境技术结合临床实践经验作为基础,能够对不同方面的认知语言功能进行治疗和训练。此外,与系统配套使用的符合人体工学的触屏式操作台的设计,使患者训练操控更为简单。     

Affective computing vs. affective placebo: Study of a biofeedback-controlled game for relaxation training

Relaxation training is an application of affective computing with important implications for health and wellness. After detecting user׳s affective state through physiological sensors, a relaxation training application can provide the user with explicit feedback about his/her detected affective state. This process (biofeedback) can enable an individual to learn over time how to change his/her physiological activity for the purposes of improving health and performance. In this paper, we provide three contributions to the field of affective computing for health and wellness. First, we propose a novel application for relaxation training that combines ideas from affective computing and games. The game detects user׳s level of stress and uses it to influence the affective state and the behavior of a 3D virtual character as a form of embodied feedback. Second, we compare two algorithms for stress detection which follow two different approaches in the affective computing literature: a more practical and less costly approach that uses a single physiological sensor (skin conductance), and a potentially more accurate approach that uses four sensors (skin conductance, heart rate, muscle activity of corrugator supercilii and zygomaticus major). Third, as the central motivation of our research, we aim to improve the traditional methodology employed for comparisons in affective computing studies. To do so, we add to the study a placebo condition in which user׳s stress level, unbeknown to him/her, is determined pseudo-randomly instead of taking into account his/her physiological sensor readings. The obtained results show that only the feedback presented by the single-sensor algorithm was perceived as significantly more accurate than the placebo. If the placebo condition was not included in the study, the effectiveness of the two algorithms would have instead appeared similar. This outcome highlights the importance of using more thorough methodologies in future affective computing studies.
