Alterix Ltd 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 developed 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 a novel approach for utilising the Bluetooth active stylus developed for Apple devices on Windows 10 computers with large scale interactive multi-touch monitors. The proposed upgrade of our touch electronics will allow us to extend the capabilities of an ordinary multi-touch panel towards those of a fully functional digitiser with support for digital ink capabilities introduced in the most recent Anniversary Update to Windows 10.

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.

Alterix is developing new algorithms for running fast and highly sensitive measurements on a matrix projective capacitive sensing system for unlimited multi-touch detection. This approach uses inexpensive off-the-shelf electronics and achieves a substantial improvement in the signal-to-noise ratio over existing projective capacitive touch systems. By achieving a hundred-fold increase in the measurement speed compared to the touch interfaces commonly used in tablets and mobile phones, our technology scales easily to provide multi-touch functionality for large displays with diagonal sizes up to 250 cm and fully conforms to Windows 8 certification . This technology will enable the company to invade the market for interactive whiteboards (IWB) with a disruptive product and in the medium term has immense potential in consumer electronics in extending the ‘smart pad’ experience to large-scale TV displays. Current feasibility study is needed to develop new radical approaches for accelerating data processing algorithms in order to run all the required calculations in the microcontroller instead of the PC.

None of the existing technical solutions is capable of meeting specification for interactive displays with a diagonal size exceeding 40”. Alterix has developed a new algorithm for running fast and highly sensitive touch measurements. The inherently low cost of the solution make it possible to integrate multi-touch functionality into medium and large scale displays with up to 85” diagonal size for large volume markets. It is of strategic importance for us to develop cheap manufacturing methods for large touch display overlays and to provide new ways for integrating our proprietary electronics with the physical sensor grid structure. With this view we aim to develop novel approaches based on using ultrafine nearly invisible metallic wire grids. Our new design will help to replace the indium material in touch display overlays and will improve recyclability of the final product enabling the recovery of the glass and laminate materials at the end of the product life.
