UI in smart phones: new finger print sensor and Ultra sonic touch interface
The smartphone user interface still has a lot to improve with huge challenges to pack such interfaces in already compacted space. Smart phone developers are now seeing market-growth opportunity in interfacing fingerprint sensors in their phones. Synaptics has unveiled a new optical-based fingerprint sensors which can be placed under the cover glass including 2.5D glass located in the front, bottom bezel of Smart phones. This new fingerprint sensor eliminates the need of button cutouts and glass thinning processes.
Synaptics FS9100 optical fingerprint sensor can support high-resolution scanning through 1mm of full cover glass and enables clean, button-free industrial designs. Synaptics is partnering with China based OXi Technology, who has developed patented optical fingerprint technology.
FS9100 supports wet fingers and is durable, scratchproof, waterproof, and no ESD issues.
Based on Synaptics’ SentryPoint technology FS9100 supports secure authentication features including Quantum Matcher with PurePrint anti-spoof technology. PurePrint examines fingerprint images using unique artificial intelligence technology to distinguish between fake and actual fingers.
This new fingerprint sensors are expected to be sampled in the first quarter of year 2017 the production to be followed a quarter later.
Sentons licensed the Cadence Tensilica ConnX BB32EP DSP for a new ultrasound technology that is dramatically changing the human interface landscape for mobile and touch-enabled devices.
On the whole touch interface innovation, the smart phone manufacturers can look forward for ultrasound-based sensing technology which allows touch sensing not only on glass but also on metal and curved surfaces. It also allows force and pressure sensing with zero deformation of the touch surface. Sentons is the company which is developing such touch interface using advanced digital signal processors with vector processing abilities.
Sentons also developed digital pen technology called SonaPen to write on its touchscreen technology just like ink pen.
