Speeding innovation for industry
CES 2019 : CEA Tech to exhibit at CES Las Vegas on January 8–11
PIXCURVE : Lighter and more compact optical systems without compromising image quality.LOTUS : Richer touch interaction through hyper-localized feedback.
Pixcurve is an innovative solution for the imaging market. This new technology makes it possible to manufacture optical components that are curved like the human retina. The result? Fewer lens elements arerequired in devices like digital cameras, smartphones, microdisplays, and virtual-reality glasses. With Pixcurve, camera manufacturers can finally get the cost effective, compact, easy-to-assemble optical components they need to bring their products to new levels of performance.
In recent years, touch interfaces have multiplied, becoming the new standard for human-machine interaction. However, the narrow range of expression offered by touch interfaces limits the features that these devices can deliver. LOTUS, which stands for LOcalized Tactile Feedbackon smart sUrfaceS, is a novel solution that enhances the user experience with an interactive touch surface that is both tactile and haptic. Previous touch interfaces—if they were able to detect the positions of several fingers—could only provide haptic feedback in the form of vibration over the entire surface.The technology developed by researchers at List, a CEA Tech Institute,offers two advantages: It makes it possible to detect the positionof multiple fingers and the pressure exerted by each of them; and it alsodelivers individual haptic feedback to each finger. Coupled with a visualinterface, Lotus enables the user to interact with digital content and offersunparalleled tactile rendering of texture and relief. This haptic-feedbacktechnology leverages piezoelectric transducers that control vibration,enabling rich, realistic, and detailed multi-user interaction.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
