Hemispatial neglect is a common disorder that can occur after a lesion in the right hemisphere. Its main characterization is the difficulty in processing visual stimuli emanating from the space contralateral to the lesion. Pencil and paper tests (such as target cancellation, line bisection, or drawing copy) are used to diagnose neglect. We propose using virtual reality technology and haptic force feedback to enhance pencil and paper tests. Our system can track the patients' eye-gaze and their hand movements. Also, the efficiency of several techniques used to decrease the neglect in different sensory spaces are investigated.
半侧空间忽视是一种常见的疾病，可发生于右半球病变后。其主要特征是难以处理来自病变对侧空间的视觉刺激。纸笔测试（如目标取消、直线二等分或临摹绘图）用于诊断忽视。我们建议使用虚拟现实技术和触觉力反馈来增强纸笔测试。我们的系统可以跟踪患者的目光和手部动作。此外，还研究了几种用于减少不同感觉空间忽视的技术的有效性。
