    Vintage vacuum fluorescent display controlled with Arduino Due

    Vacuum fluorescent displays (VFDs) have a distinct cool blue-greenish glow, and were once used in a wide range of devices, from VCRs to microwave ovens and even car dashboards. Although extremely popular way back when, they can be more difficult to source today. In the video below, Scotty Allen of the Strange Parts YouTube channel takes on the challenge of getting a $600 ISE (now Noritake) display up and running with an Arduino Due.

    The process starts with examining the datasheet to find that the Due’s 3.3V logic can indeed drive the 20×2 character display, then he constructs a custom adapter board to do just that. After more datasheet lurking, head scratching and hacking, he finally got it to show “Hello world!” toward the end of the clip, along with some simple animations. 

    The VFD control is part of a larger build that will be revealed in the future, and a good reminder of just how much trial and error is needed to succeed in making something awesome.

    Single-handed smartwatch text entry with WrisText

    Arduino Team — July 26th, 2018

    Smartwatches can keep us informed of incoming information at a glance, but responding still takes the use of another hand, potentially occupied by other tasks. Researchers at Dartmouth College are trying to change that with their new WrisText system.

    The device divides the outside of a Ticwatch 2 into six sections of letters, selected by the movement of one’s wrist. As letters are chosen, possible words are displayed on the screen, which are then selected automatically, or by rubbing and tapping gestures between one’s finger and thumb. 

    The prototype employs an Arduino DUE to pass information to a computer, along with proximity and piezo sensors to detect hand and finger movements. 

    We present WrisText – a one-handed text entry technique for smartwatches using the joystick-like motion of the wrist. A user enters text by whirling the wrist of the watch hand, towards six directions which each represent a key in a circular keyboard, and where the letters are distributed in an alphabetical order. The design of WrisText was an iterative process, where we first conducted a study to investigate optimal key size, and found that keys needed to be 55o or wider to achieve over 90% striking accuracy. We then computed an optimal keyboard layout, considering a joint optimization problem of striking accuracy, striking comfort, word disambiguation. We evaluated the performance of WrisText through a five-day study with 10 participants in two text entry scenarios: hand-up and hand- down. On average, participants achieved a text entry speed of 9.9 WPM across all sessions, and were able to type as fast as 15.2 WPM by the end of the last day.

    More information can be found in the project’s research paper, or you can see it demonstrated in the video below.

  • Integrating a Nintendo Power Glove with today’s VR technology

    Integrating a Nintendo Power Glove with today’s VR technology

    Arduino Team — October 19th, 2017

    When the Power Glove was released in the early 1990s, the idea that you could control games with hand motions was incredible, but like the Virtual Boy that followed years later, the hardware of the day just couldn’t keep up. Today, hardware has finally gotten to the point where this type of interface could be very useful, so Teague Labs decided to integrate a Power Glove with an HTC Vive VR headset.

    While still under development, the glove’s finger sensors have shown great promise for interactions with virtual touchscreen devices, and they’ve even come up with a game where you have to counter rocks, paper, and scissors with the correct gesture.

    Making this all possible is the Arduino Due, which supports the library for communicating with the Vive tracker.

    We took a Power Glove apart, 3D scanned the interfacing plastic parts and built modified parts that hold the Vive Tracker and an Arduino Due on the glove. After some prototyping on a breadboard, we designed a shield for the Due and etched it using the laser-cutter transfer technique. We then soldered all components and spray-painted the whole shield to protect the bare copper. After mounting the tracker and tweaking the code by matzmann666, we had the glove work.

    If you’d like to see the details of what has been accomplished so far, check out the Teague Labs team’s design files and code on GitHub.
