Calterah unveiled the Dubhe Ultra-Wideband (UWB) SoCs which makes consumers bid farewell to intricate button pressing on TV remotes and enjoy a whole new way of interaction.
Air mice enabled by Calterah Dubhe UWB chips break the boundaries of traditional button-based remote controls. With just a light move, users can precisely and intuitively control TVs. Built for connectivity and sensing, the chips will unlock more intelligent interaction scenarios for users.
An air mouse system consists of a receiver in the TV and a remote controller, both of which integrate a UWB SoC and an inertial measurement unit (IMU) chip. Air mice for both connectivity and sensing can be developed with Calterah’s latest Dubhe series of UWB SoCs.
The series is not only the world’s first IEEE 802.15.4ab-compliant UWB chips, but also China’s first UWB chips officially certified to FiRa® Core 3.0. The Dubhe series includes two versions: CAL1104 (1T4R) and CAL1106 (2T4R), which feature the optimal receiving path sensitivity in the industry and more powerful ranging and angular measurement and offer an ultra-low power consumption mode.
In the air mouse system, the Dubhe UWB chip determines pointing positions based on accurate ranging and angular measurement, while the IMU chip further improves pointing precision by capturing the physical orientation changes of the remote control in real time.
Together, these two chips achieve complex operations, such as sliding, dragging, pointing and choosing, and even writing and drawing—creating highly-efficient pointing control at your fingertips.
As an added benefit, the high-performance radar sensing function of Dubhe chips can enable detection of human presence and positions in front of the TV, empowering smart air mice for both connectivity and sensing. In the radar mode, if the Dubhe chip detects someone approaching, the TV switches to the art mode automatically, creating a beautiful and relaxing ambiance.
Plus, the Dubhe chip can identify human positions relative to the TV, which enables the TV to smartly adjust its picture quality, volume, and other parameters accordingly, fully optimizing the watching experience for users. After users leave, the Dubhe chip accurately determines that no one is in front of the TV and then enables the TV to turn off automatically to save energy.
From mechanical buttons to intuitive pointing control, from passive response to active sensing, Calterah’s UWB chip technology will bring a brand-new smart experience of human-machine interaction. As smart IoT evolves, Calterah Dubhe UWB SoCs, with outstanding performances, provide reliable and fundamental support for air mouse applications.
Going forward, Calterah will continue optimizing applications of UWB semiconductor technology in smart home, consumer electronics, and other fields, advancing the development of more efficient human-machine interaction, for smart experiences at your fingertips.
