Improve Mobile UX with iBeacons

Enable indoor location services with Bluetooth Low Energy alerts

In the last couple of months, iBeacon is making a lot of noise. iBeacons are small wireless sensors placed inside any physical space that transmit data to your phone using Bluetooth Low Energy (also known as Bluetooth 4.0 and Bluetooth Smart). Using Bluetooth Low Energy (BLE), iBeacon opens up new opportunities by creating a beacon around regions so your app can be alerted when users enter them. Apple quietly rolled out the iBeacons framework as part of iOS 7, but lots of iBeacon manufacturers (Estimote, Roximity Beacons, Adomalay, Kontact etc.) are already emerging. It is going to play an important role in several areas.

Tiny Emulator, iBeacon iPwn, Filter Principles, and Steadicam

  1. 4043-byte 8086 Emulator manages to implement most of the hardware in a 1980’s era IBM-PC using a few hundred fewer bits than the total number of transistors used to implement the original 8086 CPU. Entry in the obfuscated C contest.
  2. Hacking the CES Scavenger HuntAt which point—now you have your own iBeacon hardware—you can just go ahead and set the UUID, Major and Minor numbers of your beacon to each of the CES scavenger hunt beacon identities in turn, and then bring your beacon into range of your cell phone running which should be running the CES mobile app. Once you’ve shown the app all of the beacons, you’ll have “finished” the scavenger hunt and can claim your prize. Of course doing that isn’t legal. It’s called fraud and will probably land you in serious trouble. iBeacons have great possibilities, but with great possibilities come easy hacks when they’re misused.
  3. Filtering: Seven Principles — JP Rangaswami laying down some basic principles on which filters should be built. 1. Filters should be built such that they are selectable by subscriber, not publisher. I think the basic is: 0: Customers should be able to run their own filters across the information you’re showing them.
  4. Tremor-Correcting Steadicam — brilliant use of technology. Sensors + microcontrollers + actuators = a genuinely better life. Beats figuring out better algorithms to pimp eyeballs to Brands You Love. (via BoingBoing)

3D Motion Tracking, Linux of Things, Techno Panics, and Great CS Papers

  1. Witracktracks the 3D motion of a user from the radio signals reflected off her body. It works even if the person is occluded from the WiTrack device or in a different room. WiTrack does not require the user to carry any wireless device, yet its accuracy exceeds current RF localization systems, which require the user to hold a transceiver. It transmits wireless signals whose power is 100 times smaller than Wi-Fi and 1000 times smaller than cellphone transmissions.
  2. A Linux Christmas — Linux drives pretty much all of Amazon’s top-selling consumer electronics.
  3. Techno Panic Timeline — chart from Exposing the War on Fun showing the fears of technology from 1493 to the modern day.
  4. Best Paper Awards in CS Since 1996 (Jeff Huang) — fantastic resource for your holiday reading.

History of the Future, Managing without Managers, Intellectual Ventures, and Quantified Cigarette

  1. A History of the Future in 100 Objects — is out! It’s design fiction, describing the future of technology in faux Wired-like product writeups. Amazon already beating the timeline.
  2. Projects and Priorities Without Managers (Ryan Carson) — love what he’s doing with Treehouse. Very Googley. The more I read about these low-touch systems, the more obviously important self-reporting is. It is vital that everyone posts daily updates on what they’re working on or this whole idea will fall down.
  3. Intellectual Ventures Patent Collection — astonishing collection, ready to be sliced and diced in Cambia’s Lens tool. See the accompanying blog post for charts, graphs, and explanation of where the data came from.
  4. Smokio Electronic Cigarette — the quantified cigarette (not yet announced) for measuring your (electronic) cigarette consumption and uploading the data (natch) to your smartphone. Soon your cigarette will have an IPv6 address, a bluetooth connection, and firmware to be pwned.

Wearable computing and automation

The Jawbone UP shows the promise available in all kinds of wearable sensors.

In a recent conversation, I described my phone as “everything that Compaq marketing promised the iPAQ was going to be.” It was the first device I really carried around and used as an extension of my normal computing activities. Of course, everything I did on the iPAQ can be done much more easily on a smartphone these days, so my iPAQ sits in a closet, hoping that one day I might notice and run Linux on it.

In the decade and a half since the iPAQ hit the market, battery capacity has improved and power consumption has gone down for many types of computing devices. In the Wi-Fi arena, we’ve turned phones into sensors to track motion throughout public spaces, and, in essence, “outsourced” the sensor to individual customers.

Phones, however, are relatively large devices, and the I/O capabilities of the phone aren’t needed in most sensor operations. A smartphone today can measure motion and acceleration, and even position through GPS. However, in many cases, display isn’t needed on the sensor itself, and the data to be collected might need another type of sensor. Many inexpensive sensors are available today to measure temperature, humidity, or even air quality. By moving the I/O from the sensor itself onto a centralized device, the battery power can be devoted almost entirely to collecting data.

Software, hardware, everywhere

Software and hardware are moving together, and the combined result is a new medium.

Real and virtual are crashing together. On one side is hardware that acts like software: IP-addressable, controllable with JavaScript APIs, able to be stitched into loosely-coupled systems—the mashups of a new era. On the other is software that’s newly capable of dealing with the complex subtleties of the physical world—ingesting huge amounts of data, learning from it, and making decisions in real time.

The result is an entirely new medium that’s just beginning to emerge. We can see it in Ars Electronica Futurelab’s Spaxels, which use drones to render a three-dimensional pixel field; inBaxter, which layers emotive software onto an industrial robot so that anyone can operate it safely and efficiently; in OpenXC, which gives even hobbyist-level programmers access to the software in their cars; in SmartThings, which ties Web services to light switches.

The new medium is something broader than terms like “Internet of Things,” “Industrial Internet,” or “connected devices” suggest. It’s an entirely new discipline that’s being built by software developers, roboticists, manufacturers, hardware engineers, artists, and designers.

Ginger.io: Putting the Patient-Provider connection at the center

A tool for outreach to patients produces unexpected benefits

This posting was written by guest author Julia Bernstein of Ginger.io. Ginger.io’s CEO Anmol Madan will be speaking on this topic at Strata Rx.

The traditional, office-based model for health care is episodic. The provider-patient relationship exists almost completely within the walls of the exam room, with little or no follow-up between visits. Data is primarily episodic as well, based on blood pressure reading done at a specific time or surveys administered there and then, with little collected out of the office. And even the existing data collection tools—paper diaries or clunky meters—are focused more on storing data that on connecting the patient and provider through that data in real time.

There is no way to get in touch when, for instance, a patient’s blood sugar starts varying wildly or pain levels change. The provider often depends on the patient reaching out to them. And even when a provider does put into place an outreach protocol, it is usually very crude, based on a general approach to managing a population as opposed to an understanding of a patient. The end result is a system that, while doing its best within a difficult setting, is by default reactive instead of proactive.

The Role of Big Data in Personalizing the Healthcare Experience: Mobile

Sensors, games, and social networking all create change in health and fitness

This article was written with Ellen M. Martin and Tobi Skotnes. Dr. Feldman will deliver a webinar on this topic on September 18 and will speak about it at the Strata Rx conference.

Cheaper, faster, better technology is enabling nearly one in four people around the world to connect with each other anytime, anywhere, as online social networks have changed the way we live, work and play. In healthcare, the data generated by mobile phones and sensors can give us new information about ourselves, extend the reach of our healers and help to accelerate a societal shift towards greater personal engagement in healthcare.
