If you’ve ever piloted a drone, you’ll know that utilizing a joystick-style controller takes some getting used to. MIT scientists have developed what they claim is a more intuitive control system, that reads the operator’s muscle signals.Continue Readi… Continue reading MIT tech uses muscle signals to control a drone
If we really want wearable computing to take off as a concept, we’re going to need lightweight input devices that can do some heavy lifting. Sure, split ergo keyboards are awesome. But it seems silly to restrict the possibilities of cyberdecks by limiting the horizons to imitations of desk-bound computing …read more
Gesture control is a technology that has floated around for quite a while, but never quite reached mainstream acceptance. Wii Bowling was fun for a while, but we’re not regularly using gestures to open doors or order pizza just yet. Doing it yourself can be quite easy, however, as [RC …read more
It’s hard to beat the fidelity and durability of printed text on paper. But the e-paper display gets pretty close, and if you couple it will great design and dependable features, you might just prefer an e-reader over a bookshelf full of paperbacks. What if the deal is sweetened by …read more

It’s generally understood that most vehicles that humans interact with on a daily basis are used with some kind of hand controlled interface. However, this build from [Avisha Kumar] and [Leul Tesfaye] showcases a rather different take. A single motion input provides both steer and foward/reverse throttle control.
The project consists of a small car, driven with electric motors at the rear, with a servo-controlled caster at the front for steering. Controlled is provided through PIC32 microcontroller receiving signals via Bluetooth. The car is commanded with a hand controller, quite literally — consisting of an accelerometer measuring pitch and roll …read more

[Dennis] aims to make robotic control a more intuitive affair by ditching joysticks and buttons, and using wireless gesture controls in their place. What’s curious is that there isn’t an accelerometer or gyro anywhere to be seen in his Palm Power! project.
The gesture sensing consists not of a fancy IMU, but of two potentiometers (one for each axis) with offset weights attached to the shafts. When the hand tilts, the weights turn the shafts of the pots, and the resulting readings are turned into motion commands and sent over Bluetooth. The design certainly has a what-you-see-is-what-you-get aspect to it, …read more

[Dimitris Platis] wanted to add gesture control to his PC. You’d think that would be expensive, but by combining a diminutive Arduino, a breakout board with a gesture controller, and an interconnect PCB, he managed to pull it off for about $7. That doesn’t include the optional 3D-printed case and we think you could omit the interconnect board if you don’t mind some wires and further cut costs. [Dimitris] calls it Nevma, and you can see how the device works in the video below.
The heart of the project is a sensor that measures light and motion. The chip and …read more
Movies love to show technology they can’t really build yet. Even in 2001: A Space Oddessy (released in 1968), for example, the computer screens were actually projected film. The tablet they used to watch the news looks like something you could pick up at Best Buy this afternoon. [CircuitDigest] saw Iron Man and that inspired him to see if he could control his PC through gestures as they do on that film and so many others (including Minority Report). Although he calls it “virtual reality,” we think of VR as being visually immersed and this is really just the glove, …read more

If we believe science fiction — from Minority Report to Iron Man, to TekWar — the future of computer interfaces belongs to gestures. There are many ways to read gestures, although often they require some sort of glove or IR emitter, which makes them less handy (no pun intended).
Some, like the Leap Motion, have not proved popular for a variety of reasons. Soli (From Google’s Advanced Technology and Projects group) is a gesture sensor that uses millimeter-wave RADAR. The device emits a broad radio beam and then collects information including return time, energy, and frequency shift to gain …read more
