认知负荷下触觉特性有效性的探索性研究
The Effectiveness of Haptic Properties Under Cognitive Load: An Exploratory Study
摘要：
随着可穿戴设备的兴起，触觉接口越来越倾向于以环境方式传达信息。尽管有这种期望，现有的指导方针是在研究中制定的，参与者的重点完全是触觉任务。在这项工作中，我们系统地研究了触觉信号的属性所施加的认知负荷。参与者在前臂上佩戴触觉设备，并被要求执行1-back任务。每个实验条件隔离触觉信号的个体属性（例如，振幅、波形、节律），并且要求参与者识别数据的梯度。我们评估了16名参与者的每种情况，测量参与者的响应时间、出错率，以及定性和定量调查（例如，NASA TLX）。我们的研究结果表明，性别和语言差异可能会影响偏好的一些属性，参与者更喜欢的属性，可以快速识别，幅度施加最低的认知负荷。
英文摘要：
With the rise of wearables, haptic interfaces are increasingly favored to communicate information in an ambient manner. Despite this expectation, existing guidelines are developed in studies where the participant's focus is entirely on the haptic task. In this work, we systematically study the cognitive load imposed by properties of a haptic signal. Participants wear a haptic device on their forearm, and are asked to perform a 1-back task. Each experimental condition isolates an individual property of the haptic signal (e.g., amplitude, waveform, rhythm) and participants are asked to identify the gradient of the data. We evaluate each condition across 16 participants, measuring participants' response times, error rates, and qualitative and quantitative surveys (e.g., NASA TLX). Our results indicate that gender and language differences may impact preference for some properties, that participants prefer properties that can be rapidly identified, and that amplitude imposes the lowest cognitive load.
