This between-group study investigated participants' experiences of tactile feedback patterns when asked to hug a virtual character. Five experimental conditions were developed, one with no tactile feedback and four with tactile feedback. The participants were placed in a virtual city and informed they would be meeting a virtual friend, who they were instructed to hug once the character came close to them. During the virtual hug, one of the five experimental conditions was examined. Immediately after the hug, participants were asked to complete a questionnaire to capture their experiences. The results obtained from this study indicated that: (1) even if the tactile feedback is not considered to be highly accurate in terms of timing, duration, and position, as long as it is perceived as less persistent, it provides a more positive experience; (2) the perceived realism of the virtual hug is strongly correlated with the perceived realism of the tactile feedback; and (3) the female participants had a more intense interaction with the virtual character (friend) compared with the male participants. Limitations and future study directions are discussed.

通过虚拟和触觉拥抱来理解体现人与虚拟角色的交互

这项组间研究调查了参与者在被要求拥抱虚拟角色时的触觉反馈模式体验。开发了五种实验条件，一种没有触觉反馈，四种有触觉反馈。参与者被放置在一个虚拟城市中，并被告知他们将遇到一个虚拟朋友，一旦角色靠近他们，他们就会被指示拥抱他。在虚拟拥抱期间，检查了五个实验条件之一。在拥抱之后，参与者立即被要求完成一份问卷以记录他们的经历。从这项研究中获得的结果表明：（1）即使触觉反馈在时间、持续时间和位置方面不被认为是高度准确的，只要它被认为不那么持久，它就提供了更积极的体验; (2)虚拟拥抱的感知真实感与触觉反馈的感知真实感强相关；(3) 与男性参与者相比，女性参与者与虚拟角色（朋友）的互动更为强烈。讨论了局限性和未来的研究方向。
