Bluetooth low energy watch platform serves as smartphone control

March 18, 2013 // By Julien Happich
Developed by wireless sports & fitness monitoring developer and manufacturer Dayton Industrial, the Portable Control Display Device (PCDD) is designed to be used as a secondary bi-directional smartphone interface using Bluetooth low energy transmission.

Featuring a 240x240 pixel TFT full color active matrix touchscreen LCD display, the production-ready watch and touchscreen display device can control smartphones and installed apps from a user's wrist via Bluetooth low energy as provided by Nordic Semiconductor’s nRF51822 SoC. The unit also comes with auto-activation 3D motion sensing, an auto-dimming ambient light sensor, a 3-meter smartphone range, and support for up to eight ANT+ wireless peripherals.

The nRF51822's class-leading ULP performance and integration enables the Dayton PCDD to deliver up to two days of operating life from a built-in 3.7V lithium-polymer USB or mains rechargeable battery. The PCDD comes in a 13.5mm-thick 48x44mm anodized aluminium watch form-factor casing.

The product platform features a fully customizable proprietary OS powered by a higher performance ARM9-based embedded CPU core with AVDSP video processing engine and 2D graphics processor that will allow OEMs and app developers to display almost any type of information they wish on the PCDD's display, and offer wrist-based control of almost any smartphone or app feature.

This includes features such as caller ID for incoming voice calls, missed call alerts (name and photo), SMS messaging, calenar and appointment reminders, and music control, through to social media (e.g. Facebook, Twitter, Whatsapp, and QQ) updates, local weather information, financial market updates, sports, fitness and wellness monitoring, and advanced security, proximity, and home automation features (e.g. smart utilities).
