Scan Room, Explore Virtually

December 16, 2009 by Caleb Kraft 6 Comments

[Patrick] directed us to his project for alternate realism. The final goal is to be able to walk around in a space wearing a head mounted display, exploring a virtual representation of that space. This virtual representation could be altered, stylized, augmented and modified in countless ways. It is an exploration in perception, similar to enjoying different styles of painting, we could enjoy different styles of viewing a real space. Currently, it isn’t quite real time. He has to scan a room with a somewhat bulky device, then plug into his display to explore it. Being able to scan quickly and reliably enough shouldn’t be far off. [Patrick] notes that others have done almost real time scans at home already.

Tiny Keyboard/touchpad Has “hack” Written All Over It

November 26, 2009 by Phil Burgess 27 Comments

Yes, we know, this is not a hack, yet it just has the vibe of something we’ll likely be seeing in many small form-factor systems and wearable hacks in the future.

The USB Wireless Handheld Keyboard is a diminutive keyboard and mouse replacement with a passing resemblance to a BlackBerry PDA — where the screen has been replaced with a laptop-style trackpad sensor. This seems a shoo-in for home theater PC use; it’s unobtrusive and won’t look out of place on the coffee table alongside the universal remote. But any tiny system requiring only occasional input could likely benefit.

The keyboard layout is funky as heck, though likely adequate for its intended use of couch web-surfing and interactive messaging (or whatever wild applications our readers will surely come up with). A USB wireless receiver and a charging cable are included in the $62 package. Video after the break…

Make Any Gloves Work With A Touch Screen

November 25, 2009 by Phil Burgess 16 Comments

The chill of autumn is upon us, and with it comes the awkward sport of trying to work touch-sensitive phones and gadgets with gloved fingers. One can try toughing it out with fingerless gloves, or we’ve seen some costly solutions in the forms of specialized gloves and capacitive-compatible styluses, but sometimes simple is best: all it takes is a few stitches of conductive thread in the fingertips.

Conductive thread is available from various sources; SparkFun Electronics comes naturally to mind, but most vendors carrying the LilyPad Arduino will stock a suitable thread as well. Don’t fret if you’ve never sewn before — just a few simple loops are required, and it doesn’t need to be especially tidy. In principle this should work for trackpads and capacitive mice as well, if you use those in the field. For multitouch devices, add a separate conductive bit to each fingertip.

TI Sports Watch For Hacking

November 25, 2009 by Mike Szczys 59 Comments

How would you like to have a 3-axis accelerometer, pressure sensor, temperature sensor, RF wireless, and an LCD screen in a development package? What if we told you that you can have it in the form factor of a wristwatch offering from Texas Instruments? How much would you pay for such a device? Quit guessing, you can pick it up for just $49 with an estimated delivery in mid-February of next year.

Our tip-line has been packed with emails about this since it was announced on Monday. The device ships with the firmware to serve as a sports watch with heart rate monitor. The price is pretty good just for that functionality but this package also includes a USB programming and emulation dongle so that you can develop your own firmware. It looks like the included development software is written for Windows but we’re hoping you can get it running on other platforms as well.

The LCD is a segment display, so you won’t see DOOM running on board. That said, we expect your first project to turn this into a wireless controller using the buttons and accelerometer.

Tauntaun Costume

[Scott Holden] went all out this year and built an amazing Tauntaun costume. The Tauntaun from Star Wars was massive, standing 8 feet tall, and usually carrying a rider. [Scott] wanted to make it the correct size, and ultimately pulled it off. He had to build custom stilts to get the leg angle correct as drywall stilts were too straight. The rest is mainly pvc and fur. We think he did a fantastic job on this. The effect is quite nice, and we can imagine that in person it is even better.

Take note at the bottom of page 3. Apparently, he got pinned in the costume in his workshop and almost had to spend the night on the floor in the costume. That’s pretty wild, at least he was warm.

Biking Through Google Street View

[Aki] wanted to do some stationary cycling to get in shape. Unfortunately, his stationary cycle is located in his garage which doesn’t supply much inspiration or amusement. His solution was to build a VR rig so that he could ride around inside google street view. He has rigged a simple sensor to his wheel to determine his speed and he’s using a vuzix VR 920 as a display and orientation sensor. While he notes that it isn’t perfect, or even reliable, we think it is pretty cool. He can go sight-seeing, while getting in shape from his own garage. We have to wonder if he gets a headache after a while though.

EyeWriter Is The Fruit Of The KanEye Project

November 11, 2009 by Mike Szczys 17 Comments

The EyeWriter is an open source eye tracking initiative. This is the mature version of the KanEye project we covered in April. Collaboratively developed by Free Art and Technology (FAT), OpenFrameworks, and the Graffiti Research Lab, they seek to aid a friend of theirs who suffers from the degenerative muscle disease ALS.

They’ve come a long way since we last looked in on the progress. The hardware used is pretty much the same: a set of sunglasses sans lenses with the CCD from a Sony PlayStation 3 Eye mounted in front of one eye. IR LEDs surround the CCD and point at the eye to increase the contrast between pupil and the rest of the eye. The major improvement comes with the software. Eye tracking appears to be extremely precise and they’ve written a custom drawing program to take advantage of their interface. Check in on their developer page for source code and a video walk-through of the software.

After the break you can see video of [Tempt1] using the system to create some tags. We’re thankful for the success this project has seen as this guy can do a lot better with his eye than we can with our hands.
