Experimenting with Gesture Sensors

Table of contents ...  

For many years, computers have been controlled by “touched” devices such as mouses, keyboards, and touchscreen displays. But today there is a growing trend for using touch-free gesture control. A good example of touch-free gesture control is in the automotive cockpit, where gesture recognition technology can enable the control of infotainment systems, thereby ensuring safety by allowing the driver to keep his eyes on the road. While gesture control seems like something out of the distant future (i.e., Star Trek), it is now being successfully integrated into smart appliances, touch-free smart home hubs and thermostats, gaming controllers, virtual reality systems, and more. To that end, let's take a closer look at the use of gesture sensing.

Using a gesture sensing evaluation kit by Maxim Integrated, this competition focuses on experimenting with gesture sensing. Participants will have an opportunity to experiment, test, or build a gesture sensor project. Before we talk about what the participants will receive in the Challenger's kit, and the great prizes they are competing for, let's talk about how to enter this competition, the timeline, and some FAQs.

The MAX25405 Optical IR Sensor Evaluation Kit (EV kit) is a complete system for demonstrating the MAX25405 optical IR sensor in a typical gesture and proximity-sensing application. The MAX25405 enables recognition of the following gestures:
  • Hand Swipe Left, Right, Up, and Down
  • Finger/Hand Rotation Clockwise and Counter-Clockwise
  • Air Click
  • Proximity Detection and Linger-to-Click

The application circuit operates by illuminating the user’s hand with a precision-controlled IR light source and measuring the reflected signal with the MAX25405’s 6x10 (60 pixel) IR sensor array. The four-LED IR light source is PWM controlled with external FETs from the MAX25405’s onboard FET driver. The return signal is analyzed with an embedded microcontroller that interprets the gestures.
