Immersive Feedback Using Inertial Sensors

Zero Point Motion是一家将一种新型颠覆性惯性传感器商业化的初创公司，该传感器利用光子学实现超低噪音的运动跟踪，与智能手机、汽车或游戏控制器中的现有传感器相比，定位精度提高了100倍以上。凭借额外的灵敏度，我们的传感器增强了跟踪手指运动等复杂精细运动的能力，从而实现了用户和AR/VR应用程序之间的新交互。我们的加速度计的灵敏度带来了一个令人兴奋和深刻的结果，那就是探索检测身体运动的能力，因为它从心脏喷射血液中反弹。这就是众所周知的弹道心动图，提供心率和心脏功能的测量。通过我们的传感器提供的灵敏度提高，该项目通过简单的初始演示来跟踪单个手指的运动，同时使用臂带或鞋垫进行ballocardiography。例如，测量对屏幕或虚拟现实中呈现的不同选择的反应，通过手指手势来同步选择选项。涉及手指追踪的基本谜题可以与ballo -心动图一起使用，以理解游戏玩法和兴奋感。通过向我们的合作伙伴UWE和x-io提供我们的传感器原型的早期访问，我们通过访问嵌入式系统传感器应用，VR/AR，生物力学运动捕捉和无线数据记录方面的深厚专业知识，加强了我们的概念验证。UWE在智能系统，机器视觉和生物传感方面拥有世界一流的记录，在AR/VR领域拥有最先进的设施。这是一个成为新兴生物工程市场领导者的独特机会，该市场已经生产出用于手部互动的超声波传感器，以推断情绪健康。与超声波设备不同，我们的传感器更有能力跟踪3D运动，并通过额外的分辨率通过弹道心动图添加未开发的信息。在完成这项初步的工业研究后，我们可以启动或激发与行业最终用户（如内容创作者）进行更深入的研究，并邀请生物工程和心理学方面的关键专家，他们可以量化我们通过ballo心动图检测到的生理行为与人类情感和沉浸感之间的联系。

Zero Point Motion is a start-up commercialising a new disruptive type of inertial sensor that uses photonics to achieve ultra-low noise tracking of motion, improving positioning accuracy by over 100x compared to existing sensors inside smartphones, cars or game controllers.With additional sensitivity, our sensors enhance the ability to track complex and fine motion such as finger motion, enabling new interactions between user and AR/VR applications. An exciting and profound outcome of the sensitivity of our accelerometers is exploring the ability to detect the motion of the body as it recoils from the heart ejecting blood. This is known as ballistocardiography and provides measurements of both heart rate, as well as heart function.With the improved sensitivity offered by our sensors, this project looks at tracking the motion of a single finger whilst simultaneously performing ballistocardiography with an armband or insole through simple initial demonstrations. For example, measuring the response to different choices presented on a screen or in VR, synchronised by the selected options through finger gestures. Basic puzzles that involve finger tracing can be used alongside the ballistocardiogram to understand game play and excitement. By providing early access of our sensor prototypes to our collaborators UWE and x-io, we strengthen our proof-of-concept by accessing deep expertise in the application of sensors for embedded systems, VR/AR, motion capture for biomechanics and wireless data logging. UWE has a world-class track record in intelligent systems, machine vision, and bio-sensing, with state of the art facilities in the AR/VR domain. This is a unique opportunity to become leaders in an emerging bioengineering market that has already produced ultrasonic sensors for hand-based interactions to infer emotional wellbeing. Unlike ultrasonic devices, our sensors are more capable of tracking 3D motions, and adding untapped information through ballistocardiography with additional resolution.Upon completion of this initial industrial research, we can then initiate or inspire deeper studies with industry end-users such as content creators, and invite critical experts in bioengineering and psychology who can quantify the link between the physiological behaviour we detect through ballistocardiography with human emotion and immersion.
