FingerTPS - Overview
The all-new, redesigned FingerTPS™ (Finger Tactile Pressure Sensing) system utilizes highly sensitive capacitive-based pressure sensors to reliably quantify forces applied by the human hand. It's the only practical and comfortable sensor solution that also connects wirelessly to your PC. With our powerful new Chameleon TVR Software, FingerTPS systems can be easily reconfigured and recalibrated for different uses of the hands on the fly.
FingerTPS systems also include synchronized video recording to match tactile data with actual use. Precise force data and video images can be captured and displayed in real-time via PPS's Chameleon TVR Software, which has Tivo®-like versatility in recording time-series, average and peak force measurements. |

Sensor Types
The FingerTPS consists of the following sensors:
FingerTPS Systems
Each FingerTPS system supports two hands with up to 6 sensors per hand. The main system includes the sensors, wrist-mounted interconnect harness, rechargeable wireless interface module, and USB Bluetooth transceiver. In addition, FingerTPS systems include a high quality webcam for video input and a USB load cell for calibration.
The sensors are made from a soft, conductive Lycra® that conforms to the finger to allow dextrous operations and are fastened with small Velcro® straps. Four FingerTPS sensor shapes are available: finger (available in small, medium, and large sizes), thumb (slightly shorter and available in small and large sizes), palm, and "band-aid" (available in small and large sizes) for measuring loads on inner phalanges.
The wireless interface module can be recharged using a USB port and runs continuously for over 2 hours. |

Chameleon TVRS
 The new Chameleon TVRS™ (Tactile Visualization and Recording Software) offers real-time visualization, analysis, and playback of your FingerTPS data. Chameleon TVRS allows you to collect and view video and FingerTPS data simultaneously.
With Chameleon TVRS, configuration and calibration of your FingerTPS system is a breeze. Simply indicate where the sensors are on the hand and press once on the included electronic reference sensor. There's no need to remember which channels are active or in what order the sensors were connected. Chameleon TVRS tracks it all for you, and you're setup and calibrated in minutes.
Once you are collecting data, you can view selected sensors on the strip chart display. Digital displays show the real-time, time-averaged, or maximum values for all connected sensors, plus the total and peak force for each hand. At any time, you are free to change the units for display and export.
Features & Benefits:
- Auto-detects connected sensors across all available channels
- Simple, one-touch calibration
- Tivo®-like capabilities allow simplified recording & editing
- Video integration synchronizes actions to analytical data
- Supports simultaneous collection from FingerTPS and TactArray systems
