    概括

    将振动反添加到虚拟现实 (VR) 强力反模拟中,可以提高针头插入的真实性和性能. 这种双模态触觉方法,结合了动感和皮肤线索,比单模态反提供了显著的优势.

    科学领域:

    • 医疗模拟 医疗模拟
    • 触觉技术是一种触觉技术.
    • 虚拟现实 虚拟现实 虚拟现实

    背景情况:

    • 在VR针插入模拟中,力量反可以提高现实性,但也有局限性.
    • 触觉反,特别是振动触觉线索,尚未完全被作为补充物探索.

    研究的目的:

    • 为了研究在VR-Haptic针插入模拟中添加振动反到现有的力反的影响.
    • 设计和整合一个新的可编程触觉反系统.

    主要方法:

    • 开发了一个可编程的触摸反系统,使用直接数字合成 (DDS) 来驱动LRA和皮埃佐执行器.
    • 将系统集成到VR针插入模拟中.
    • 进行了一项用户研究,以测量性能,可用性和现实性.

    主要成果:

    • 与LRA单独相比,组合的振动器 (piezo和LRA) 和力反提高了针头插入性能.
    • 振动感应反增强了现实性,超出了单纯的力反.
    • 参与者更喜欢联合力和振动反.

    结论:
