Chapter 1. 3DTouchPad Overview

1.1 INTRODUCTION

The 3DTou chPad is a personal computer (PC) peripheral used to extend a 2D touch pad with 3D free space gestures. It u tilizes Microchip’s projected capac itive (PCAP) sensor solutions as well as Microchip’s 3D gesture technology, GestIC 3DT ouchPad offers multi-finger tracking and surface gestures as well as free space 3D gestures above the surface.

The 3DTouchPad offers all features expected from a touch pad (precision, multi-finger tracking, multi-finge r surface gestures, s uch as swi pes and s crolling) to which it adds 3D hand gestures. It enables a more efficient, more productive usage of the touch pad area. For example, the 3D Tou chPad will all ow the user to cont rol the flow of pictur es by a wave of the hand or to control the volume of the speakers with a casual rotation.

No driver installation is needed for the 3DTouchPad; it will simply work out-of-the-box. The 3DT ouchPad is designed to be a comprehensive development platform, offering a

fully documented Software Development Kit (SDK) as well as an Application Programming Interface (API). The SDK contains reference code and enables the development of application s, driv ers and games.

2.1 GETTING STARTED

The 3DTouchPad package contains the 3DTouchPad, a mini USB cable and an information sheet. Please use the mini USB cable to connect the device to the PC.

No driver installation is required for the 3D TouchPa d. It is automatical ly detected by Microsoft Windows (HID). Th e 3DTouchPad is ready for use as soon as the right LED of the 3DTouchPad lights up. Please see Chapter 4. “Hardware” for more details on LED indication.

Note: When the 3DT ouchPad is connected to the PC for the first time, it may take

several seconds (up to several minutes) until it is ready to use. A reboot of the PC may be required if prompted by the Operating System (OS).

4.1 INTRODUCTION

The 3DTouchPad consis ts of a single four-layer PCB enclosed by a plastic hous ing. The mini USB por t provides c onnecti vity to a USB port of a PC. Three LE Ds indicat e the operating modes: 2D, 3D and Debug mode.

4.2 HARDWARE SETUP

The 3DTouchPad PCB contains the 2D touch pad surrounded by the electrodes for 3D gesture recognition. The assembly is placed on the bottom of the PCB. Figure 4-1 and Figure 4-2 show the assembly as well as the electrode structures.

4.3 3D GESTURE RECOGNITION

3D gesture recognition is realized with Microchip’s single-chip gesture solution, MGC3130. The MGC3130 is a gesture recognition, motion tracking and approach detection controller based on Microchip’s patented GestIC technology. It enables user command input with natural hand movements while utilizing the principles of electrical near-field sensing. Please find more detailed information at

www.microchip.com/gestic.

MGC3130 is connected to four Rx frame electrodes (North, East, So uth and West) located at the top of the PCB and one transmit (Tx) electrode which covers a full middle layer of the PCB. The four Rx electrodes define the edges of the 3D sensing space (X and Y direction). The sen sing space reaches a height of up to 70 mm (Z direction). Inside this sensing space, the user can perform free space gestures which are described in Table 3-2.

4.4 2D T OUCH PAD

The 2D touch functionality is reali zed with Microchip’s MTCH63104, a PIC32-based PCAP controller. It handles 12 Rx and 16 Tx nodes, which are located in the center of the PCB (top layer) in between the 3D Ges tIC Rx electrodes. T he edges of the touch pad area are marked by a raised line on the top cover.

In order to ensure system stability and r obustness, the PCAP Tx signal is driven by Microchip’s MTCH652. MTCH652 is a Tx voltage booster solution which drives the Tx signal up to 18V.

The 2D touch pad allows tracki ng of u p to ten finger s sim ultaneous ly. Besides the 2D multi-finger tracking functionality, a variety of surface gestures are implemented. These surface gestures allow for example two-finger scrolling. A complete overview of the 2D gestures is given in Table 3-1.

MGC3130 and MTCH63104 communicate via I2C™ – MTCH63104 as master and MGC3130 as slave. In addition to the I

C lines, there are two handsha ke lines which are used for the handover proces s between 3D and 2D operation. 2D as well as 3D information is sent to the P C by MTCH 63104 v ia the USB. Here by, MTCH 63104 a cts as a HID device.

4.6 OPERATING MODES AND LED INDICATIONS

FIGURE 4-4: LEDS SEEN FROM THE BACK

Three LEDs are plac ed on the bottom of the 3DTouchPad to indicate the operating mode (see Figure 4-4).

• LED 3 (indication for 3D mode): Free space gestures such a s flicks or Airw heel

will be detected.

• LED 2 (indication for 2D mode): If the user touches the surface of the pad, the

mode will change automatical ly from 3D to 2D and this LED will light up. LED 3 will be switched off. Multi-finger tracking as well as surface gestures will be detected in this mode.

• LED 1 (indic a ti o n for Debug mode): If Debug mode is enabled, neither 2D nor 3D

information will be forwarded to the Windows HID interface. Hence, all built-in Windows OS control features are disabled. 2D and 3D information can be monitored in the 3DTouchPad GUI without effects on the OS. The Debug mode can be enabled and disabled in the 3DTouchPad GUI.
