Ambient Light Sensing

Mobile phones with in-built ambient light sensor is capable of detecting ambient brightness level and auto-adjusting the screen backlight accordingly. This application not only provides a better reading experience, but helps to protects users’ eyes by promptly reduce the difference between their mobile backlight and ambient lighting. PixArt's Gesture SoC Chip comes with a built-in filter to eliminate light interference and is able to accurately reflect the brightness level of users’ surroundings.

The ambient light sensing module is highly integrated and also comes with proximity sensing capability. If you are interested with the applications or related products, please browse the product pages below.

Touch-on-Keyboard Application on Mobile Phones

Mobile phones with Touch-on-Keyboard (TOK) technology allow users to perform cursory-like navigation from a keyboard surface, providing convenient options to users who wishes to utilize multiple input methods according to their needs.

PixArt's TOK solution, derived from the CFN (Capacitive Finger Navigation) technology, could detect various types of on-keyboard finger movements including hovering, swiping, scrolling, and is also capable to identify two-finger and three-finger commands such as zooming, dragging items across the screen or show desktop/home.

PixArt’s TOK sensor supports ultimately high report rate of over 100Hz with dynamic resolution from 150 to 1200cpi, and is low in power consumption (5mA in tracking mode, 100μA in sleep mode and 7μA in shutdown mode). The in-built algorithm is so powerful that it could support the keyboard with thickness up to 3mm.

Gesture Commands on Mobile Interfaces

Be reminded of how inconvenient it was when you tried to switch songs on your smart phone while doing dishes last time. The good news is, with PixArt’s Gesture sensor and the suitable implementation, it is no longer a dream to operate your phone without touching the screen.

PixArt’s Gesture chips comes with small form factor and a built-in ambient light filter to enhance gesture recognition under strong or low lights (also known as sunlight resistance function). Through our special power saving design, the overall power consumption of these chips are effectively lowered.

Mini Navigation Pad

Navigation Pads, also known as optical touch pads, are aimed to deliver users with fast and cursory-like navigation control interface on space-constrained devices. Before touchscreen became a norm in mobile phone applications, the navigation pad was once a featured and important control method for some high-end business mobile phones.

Today, the highly integrated navigation pads are still found in computer, medical, automotive and aeronautic industries, which continues to provide convenient operating interfaces via its 2/4/8-direction or free navigation controls.
