力反馈通过允许用户分享非语言方面（如节奏、姿势等）来增强数字触摸。为了实现这一点，界面驱动用户不自觉地触摸（使用外骨骼或电肌肉刺激）；我们称之为电脑驱动触摸。不幸的是，强迫用户触摸会导致他们丧失代理感。虽然研究人员发现延迟电脑驱动触摸的时间可以保留代理，但他们只考虑了用户驱动触摸与电脑驱动触摸一致的naïve情况。我们认为这是不可能的，因为它假设我们可以完美地预测用户触摸。但是，当触觉强迫用户进入他们不想要的结果或帮助用户获得他们无法单独获得的结果时，其余的情况又如何呢？我们通过一个实验来揭示在这些新奇的情况下会发生什么。根据我们的发现，我们综合了一个框架，使数字触摸系统的研究人员能够在触觉辅助与代理感之间进行权衡。
Force-feedback enhances digital touch by enabling users to share non-verbal aspects such as rhythm, poses, and so on. To achieve this, interfaces actuate the user’s to touch involuntarily (using exoskeletons or electrical-muscle-stimulation); we refer to this as computer-driven touch. Unfortunately, forcing users to touch causes a loss of their sense of agency. While researchers found that delaying the timing of computer-driven touch preserves agency, they only considered the naïve case when user-driven touch is aligned with computer-driven touch. We argue this is unlikely as it assumes we can perfectly predict user-touches. But, what about all the remainder situations: when the haptics forces the user into an outcome they did not intend or assists the user in an outcome they would not achieve alone? We unveil, via an experiment, what happens in these novel situations. From our findings, we synthesize a framework that enables researchers of digital-touch systems to trade-off between haptic-assistance vs. sense-of-agency.
