Advanced multi-touch tracking with user palm rejection

Alterix开发了低成本电子产品，与平板电脑中使用的普通触摸界面相比，测量速度提高了100倍。我们的解决方案可以轻松扩展到对角线高达85英寸的大型传感器，并与平板电视兼容，而平板电视是交互式显示的未来所在。我们已经演示了精确跟踪来自多个手指或触控笔的触摸事件，同时拒绝来自手掌等大型物体的大多数触摸事件。市场迫切需要提供一种多点触控技术，能够始终完全拒绝用户的手掌，以便为内容创作者提供舒适的用户体验——他们经常需要使用虚拟键盘或触控笔输入数字墨水。该项目将提供一个机会来测试新算法的可行性，以彻底改进由Alterix开发的触摸识别软件，旨在确保没有来自大型物体的触摸事件报告给计算机。我们的技术将允许用户将手掌直接放在触摸屏的玻璃上，从而消除“大猩猩手臂”综合症。

Alterix has developed low-cost electronics capable of achieving a hundred-fold increase in measurement speed compared to the common touch interfaces used in tablet PCs. Our solution scales easily to large sensors with diagonals up to 85” and is compatible with the flat-panel TVs with which the future of interactive displays lies. We have already demonstrated the precise tracking of touch events from multiple fingers or a touch stylus while simultaneously rejecting most touch events from large objects like palms. There is an urgent market need to provide multi-touch technology capable of consistently and completely rejecting the palm of the user in order to achieve a comfortable user experience for the creators of content – who often need to use virtual keyboard or stylus input for digital inking. This project will provide an opportunity to test the feasibility of novel algorithms for the radical improvement of the touch recognition software developed by Alterix aiming to ensure that no touch events from large objects are reported to the computer. Our technology will allow users to rest their palms directly on the glass of the touch display thus eliminating ‘Gorilla arm’ syndrome.
