VTQA: Behavioral Data from Studies on Compression Ratios in Vibrotactile Signal Processing

Objectives: This dataset collection aims to facilitate research on the transmission of digitized vibrotactile signals over communication networks, emphasizing the importance of minimizing delay and bandwidth requirements while preserving perceptual quality in human sensory experiences.Data description: The dataset includes perceptual ratings derived from two user studies evaluating the quality of vibrotactile signals compressed using various single-point tactile codecs. Participants provided subjective quality ratings for a range of compression ratios to assess data fidelity and the extent to which compression algorithms may compromise quality in favor of file size reduction.

研究目标：本数据集合集旨在推动数字化振动触觉信号（digitized vibrotactile signals）在通信网络中的传输相关研究，重点强调在保障人类感官体验感知质量的前提下，尽可能降低传输延迟与带宽需求的重要性。
数据集说明：本数据集包含两项用户研究所得到的感知评分（perceptual ratings），用于评估采用各类单点触觉编解码器（single-point tactile codecs）压缩后的振动触觉信号质量。研究人员针对一系列压缩比设置，邀请受试者给出主观质量评分（subjective quality ratings），以评估数据保真度，以及压缩算法为缩减文件体积而可能牺牲信号质量的程度。
