1. PRoC-UI Solution for Wireless Touch Human Interface Devices (HID)
Single-Chip Solution for Capacitive Touch Sensing and 2.4 GHz Proprietary Wireless Communication

2. Wireless Touch HID Market is Booming
Windows 8 launched with new Modern UI supporting touch gestures
Windows 8 supports indirect touch through a PC’s Trackpad
Gestures can be applied to the surface of the Trackpad to achieve Windows 8 touch-based actions
Total market size is expected to increase from $0.5B in 2013 to approximately $1B in 2017
Wireless Keyboard with Trackpad
Windows 8 was designed with touch in mind
All upcoming OS would incorporate Touch Gestures
60 Million Windows 8 licenses sold in the first 10 weeks of launch
Enterprises will be deploying this Windows platform as service packs become available
Multi-touch interfaces similar to the ones on touch screens are being deployed on mice and keyboards to create touch enabled wireless HID
The era of touch interfaces on HID has begun with introduction of touch gestures on Windows 8
Wireless Touch Mouse

3. Terms You May Hear from Engineers
Report Rate (Hz)
The polling rate that determines how often the mouse sends information to your computer. Measured in Hz, this setting equates to lag time (in ms). By default, the USB polling rate is set at 125hz
Receive Sensitivity (dB)
Receive sensitivity indicates how faint an RF signal can be successfully received by the receiver. The lower the power level that the receiver can successfully process, the better the receive sensitivity
Modern UI
Modern UI Style refers to the new Windows 8 Start Screen
Modern UI design is used in reference to Windows 8 apps
System Tuning
The manual process of setting capacitive button chip parameters for optimal touch performance
Compensates for system, manufacturing, and environmental conditions and changes
Signal-to-Noise Ratio (SNR)
The ratio of the signal from the sensor, when touched, to the noise signal on an untouched sensor
High-reliability operation requires high SNR

4. PRoC-UI Terms PRoC™-UI SmartSenseTM Auto-tuning Gesture Library
Programmable Radio-on-a-Chip–User Interface solution combines 2.4-GHz proprietary WirelessUSB™-NL Radio with Cypress' CapSense® and TrueTouch® capacitive touch technologies
SmartSenseTM Auto-tuning
CapSense algorithm that continuously compensates for system, manufacturing, and environmental changes
Gesture Library
PRoC-TT, the TrueTouch variant of PRoC-UI supports Windows 8 specific gestures (See Appendix)
CapSense®
Cypress’s solution for capacitive sensing of buttons and sliders
Industry’s No. 1 solution in sales by 4x over No. 2 supplier

5. Design Problems Engineers Face
1. Battery operated devices require low power consumption
Target end applications are battery operated, HID-touch mice, wireless Trackpads, remote controllers, toys, etc.
Low active and sleep mode power consumption is required for extended battery life
2. Minimal Board Space Requirements
Current trend is to make the end equipment (keyboard, mice etc) as small as possible
New sleek designs for keyboards and mice have resulted in lower PCB space
3. Manual Tuning
Manual Tuning process is iterative and time-consuming
Leads to additional programming efforts and increases overall production cost
4. Cost Considerations – Touch for the Masses
Discreet ICs for MCU, capacitive touch controller and radio lead to a high overall BOM (Bill of Materials)
Reducing the number of ICs reduces BOM in the price sensitive wireless HID market
PRoC-UI solves these problems
Low power consumption of 1 μA in Sleep mode and 7 μA in Active mode per sensor at 500 ms scan rate
Single-Chip solution for radio, MCU and touch leading to additional board space savings
SmartSense Auto-Tuning optimizes performance by continuously compensating for system, manufacturing and environmental changes
PRoC-UI can replace 3 ICs (MCU, capacitive touch controller and radio) with one leading to significant overall BOM cost savings
