论文摘要
随着可穿戴设备的兴起，触觉界面越来越喜欢以环境方式传达信息。尽管有这样的预期，但在参与者的重点完全放在触觉任务上的研究中还是制定了现有指南。在这项工作中，我们系统地研究了触觉信号的性质施加的认知负荷。参与者在前臂上戴上触觉设备，并被要求执行1回外任务。每个实验条件都会隔离触觉信号的单个特性（例如振幅，波形，节奏），并要求参与者识别数据的梯度。我们评估16名参与者的每种状况，测量参与者的响应时间，错误率以及定性和定量调查（例如NASA TLX）。我们的结果表明，性别和语言差异可能会影响对某些特性的偏好，参与者偏爱可以快速识别的特性，并且幅度施加了最低的认知负荷。
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.
