This paper reports the effectiveness of a tactile stimulus in a virtual environment to increase people's motivations during a monotonous task by comparing a touch with only visual stimuli and another with both visual and tactile stimuli. Although touch interaction with robots showed various positive effects such as improved motivation, visual and haptic stimuli were not separated due to the form of the touch in physical environments. Virtual environments enable us to investigate such effects by separating the modality of touch: a visual-only-touch and a visual-tactile touch. We experimented in a virtual environment where participants did a monotonous task after experiencing either a visual-only-touch or a visual-tactile-touch by an agent to compare them in the context of motivation improvements and the perceived impressions. The experimental results showed that a visual-tactile touch significantly increases the motivations of the participants for monotonous tasks. On the other hand, their likability of the agents is not significantly changed by the touch modalities.

本文通过比较仅具有视觉刺激的触摸和同时具有视觉和触觉刺激的触摸，报告了在虚拟环境中触觉刺激在单调任务中增加人们动机的有效性。尽管与机器人的触摸交互显示出各种积极效果，例如提高动机，但由于物理环境中的触摸形式，视觉和触觉刺激并未分开。虚拟环境使我们能够通过分离触摸模式来研究这种效果：仅视觉触摸和视觉触觉触摸。我们在虚拟环境中进行了实验，参与者在体验了代理的仅视觉触摸或视觉触觉触摸后执行了一项单调的任务，以在动机改进和感知印象的背景下比较它们。实验结果表明，视觉-触觉触摸显着增加了参与者对单调任务的动机。另一方面，他们对代理的喜爱程度不会因触摸方式而显着改变。
