We have developed a novel and affordable way to texture virtual hands from individually taken photographs and integrated the virtual hands into a mixed reality neurorehabilitation system. This mixed reality system allows for serious game play with mirrored and non-mirrored hands, designed for patients with unilateral motor impairments. Before we can ethically have patients use the system, we must show that embodiment can be achieved for healthy users. We compare our approach’s results to previous work in the field and present a study with 48 healthy (non-clinical) participants targeting visual fidelity and self-location. We show that embodiment can be achieved for mirrored and non-mirrored hand representations and that the higher realism of virtual hands achieved by our texturing approach alters perceived embodiment. We further evaluate whether using virtual hands resized to the individual’s hand size affects embodiment. We present a 16-participant study where we could not find a significant difference with personal resized hands. In addition to rehabilitation contexts, our findings have implications for the design and development of applications where embodiment is of high importance, such as surgical training and remote collaboration.

我们已经开发出一种新颖且价格合理的方法，可以从单独拍摄的照片中提取出虚拟手的纹理，并将虚拟手整合到混合现实神经康复系统中。这种混合现实系统允许使用镜像手和非镜像手进行严肃的游戏，专为具有单方面运动障碍的患者而设计。在道德上让患者使用该系统之前，我们必须证明健康的用户可以实现该实施方案。我们将我们的方法的结果与该领域的先前工作进行了比较，并针对48位健康（非临床）参与者进行了研究，这些研究针对视觉保真度和自我定位。我们表明可以为镜像和非镜像的手表示实现实施例，并且通过我们的纹理化方法实现的虚拟手的更高逼真度会改变感知的实施例。我们进一步评估使用大小调整为个人手部大小的虚拟手是否会影响实施方式。我们提出了一项由16人参与的研究，在我们的研究中，我们没有发现个人调整后的手有显着差异。除康复环境外，我们的发现还对实施具有高度重要性的应用程序的设计和开发有影响，例如外科手术培训和远程协作。
