3D Printing and Ultrasound Help Blind Pregnant Moms Touch Their Unborn Babies
Here’s a pair of wonderful stories that were made possible with the help of 3D printing. As part of its new ad campaign in Brazil, diaper brand Huggies helped two blind expectant mothers “see” their unborn children by printing 3D models of the babies based on their ultrasound scans.
Get a box of tissues and meet Tatiana…
…and Marcia.
Awwww. According to C|NET, a company called 3D Babies does pretty much the same thing, and can even print the entire fetus. We live in magical times.

Handycam for the Mummy’s Tummy
It’s very difficult to envision proper medical care in poverty stricken places. The Mobile Ultrasound is a portable device to help expectant mothers learn more about their babies. The device has been given a refreshing makeover, allowing formidable looking medical products to look and behave more like consumer electronics. About time, right?

Ultrasound Haptic Feedback Lets You Feel Virtual Objects: Good Vibes
Virtual reality has reached the point where it can easily fool our vision and sense of depth and balance. But if it’s to be truly believable our sense of touch needs to be indulged as well. That’s the goal of the English company Ultrahaptics. The company is working on a device that allows users to “feel” something that’s not actually there.
Invented by students at the University of Bristol, Ultrahaptics uses an array of small ultrasound speakers to create “a noticeable pressure difference” on a user’s hands, creating the feeling of touching something that’s not really there. The Ultrahaptics device uses a Leap Motion sensor to track the user’s hands. This makes it possible to create simulations that lets you feel the different parts of an object, i.e. it will know if you’re touching the top, side or bottom of a virtual object and respond accordingly.
Ultrahaptics’ Ben Long said that they can improve their device by using more and smaller speakers. I wonder if it’s strong enough to simulate projectiles or hard objects like walls. You can read up on Ultrahaptics at the University of Bristol’s website.

Multi Layer Interaction Uses Ultrasound to Detect Midair Gestures: Leap Mobile
One of the Moto X’s convenient features is that you can wave your hand over it to toggle certain apps, such as silencing a call or an alarm or simply to wake the screen. Elliptic Labs’ Multi Layer Interaction technology enables what appears to be a more advanced form of Moto X’s touch-less gesture recognition.
Unlike the Moto X or the Leap Motion, which both depend on infrared LEDs and cameras, Multi Layer Interaction uses ultrasound speakers and microphones to detect gestures. According to Elliptic Labs, its technology has a 180º range and consumes less power than camera-based sensors. This enables gesture detection not just directly over the phone but even above, below or from either side of the device and from up to 20″ away, giving users more leeway. It also allows for distance-based gestures, as you’ll see in the video below.
I think touchless gestures could someday eliminate physical buttons on mobile devices, but on the other hand I can’t help but think of my phone’s poor battery.

Elliptic Labs releases ultrasound gesturing SDK for Android, will soon integrate into smartphones
Elliptic Labs has already spruced up a number of tablets by adding the ability to gesture instead of make contact with a touchpanel, and starting this week, it'll bring a similar source of wizardry to Android. The 20-member team is demoing a prototype here at CEATEC in Japan, showcasing the benefits of its ultrasound gesturing technology over the conventional camera-based magic that already ships in smartphones far and wide. In a nutshell, you need one or two inexpensive (under $1 a pop) chips from Murata baked into the phone; from there, Elliptic Labs' software handles the rest. It allows users to gesture in various directions with multiple hands without having to keep their hands in front of the camera... or atop the phone at all, actually. (To be clear, that box around the phone is only there for the demo; consumer-friendly versions will have the hardware bolted right onto the PCB within.)
The goal here is to make it easy for consumers to flip through slideshows and craft a new high score in Fruit Ninja without having to grease up their display. Company representatives told us that existing prototypes were already operating at sub-100ms latency, and for a bit of perspective, most touchscreens can only claim ~120ms response times. It's hoping to get its tech integrated into future phones from the major Android players (you can bet that Samsung, LG, HTC and the whole lot have at least heard the pitch), and while it won't ever be added to existing phones, devs with games that could benefit from a newfangled kind of gesturing can look for an Android SDK to land in the very near future.
