针对现有的电子行走辅助(ETA)系统在普及和应用中的缺陷,自行设计了一种易使用的ETA系统模型AudioMan。该模型结合图像处理和听觉显示技术,给盲人用户提供道路方向和障碍物位置等环境信息。系统提出通过控制乐音的参数来实现可听化,用可听化来传递图像信息。可用性测试和评估结果表明,AudioMan所建立的用户听觉模型比现有的ETA系统更有效。 相似文献

This paper presents a comparative study on common Parameter Mapping Sonifications (PMSons) designed to reduce the perception of instabilities during the real-time interactive exploration of noisy data streams. The objective of this study is to evaluate the capacity of these PMSons in reducing the perceived fluctuations while preserving both efficiency and accuracy of participants’ estimations during the exploration task. Based on the real application of beacon localization for rescue operations, an abstraction of the task was developed which simulates the basic concepts involved, i.e. the estimation of local maxima during the exploration of a 1D data topography. Three different PMSons were selected, based on pitch, pitch averaged over time, and tempo, evaluated for three different noise levels applied to the data. Subjects explored the auditory graph using a pen tablet to define their auditory viewpoint (i.e. position) on the topography. Evaluations were based on subjects’ ability to quickly appraise the underlying data topography along with aesthetic considerations regarding the impact of noise on the exploration task. Results showed that both tempo and pitch averaged PMSon reduced the perceived instabilities compared to pitch, while tempo preserved the response time of the sonification feedback. 相似文献

AbstractThe aim of this study was to explore operator experience and performance for semantically congruent and incongruent auditory icons and abstract alarm sounds. It was expected that performance advantages for congruent sounds would be present initially but would reduce over time for both alarm types. Twenty-four participants (12M/12F) were placed into auditory icon or abstract alarm groupings. For each group both congruent and incongruent alarms were used to represent different driving task scenarios. Once sounded, participants were required to respond to each alarm by selecting a corresponding driving scenario. User performance for all sound types improved over time, however even with experience a decrement in speed of response remained for the incongruent iconic sounds and in accuracy of performance for the abstract warning sounds when compared to the congruent auditory icons. Semantic congruency was found to be of more importance for auditory icons than for abstract sounds.Practitioner Summary: Alarms are used in many operating systems as emergency, alerting, or continuous monitoring signals for instance. This study found that the type and representativeness of an auditory warning will influence operator performance over time. Semantically congruent iconic sounds produced performance advantages over both incongruent iconic sounds and abstract warnings. 相似文献

人类对外界的感知和联系一直是人类活动研究的重点。许多产品和技术都可以结合,如最近非常流行的虚拟现实,就是将虚拟现实和残疾人的健康保障组合在一起。早期的虚拟显示设备都带有传感器,但用这些传感器进行交互对于残疾人来说十分困难。主要原因是当用户使用输入设备(键盘、鼠标、遥控器)控制虚拟现实设备的时候,操作十分复杂,没有外在的帮助,有运动障碍的人无法正常使用。为了解决以上问题,提出了用虚拟鼠标取代传统鼠标,将键盘、鼠标、遥控器的功能三合一,以可穿戴眼镜作为显示的媒介设备,简化交互过程。设计原则是通过使用一个按键,用户就可以与安装在虚拟眼镜上的系统进行交互,同时不需要很大的手指力量和手指活动幅度。我们控制变量的方式设计对比实验来评估该系统。该系统的后期测验证明了提出的系统的有效性和可靠性,而且系统整体设计十分完备。 相似文献

An electrostatic tactile display with a projected capacitive touchscreen integrated into a single panel was demonstrated. Every electrode on the panel is driven for both tactile presentation and the touch sensor. The functions are both time and spatially multiplexed, and a reference–node‐driven high‐pass filter in the touch controller filters out the noise from the tactile driving signals. 相似文献
