Smartphone app measures vital heart and respiration signs

October 6, 2011

Worcester Polytechnic Institute (WPI) researchers have developed a smart phone app that can measure heart rhythm and rate, respiration rate, and blood oxygen saturation using the phone’s built-in video camera.

As the camera’s light penetrates the skin, it reflects off pulsing blood in the finger. The app can correlate subtle shifts in the color of the reflected light with changes in the patient’s vital signs.… read more

Smartphone app produces 3D scans

April 15, 2011

3D Scan

An app developer at Georgia Tech’s College of Computing has created Trimensional, the first smartphone app that allows users to take 3D scans of faces or other objects and share them by email.

Trimensional works using an iPhone’s screen, for example, to shine four different lighting patterns on a subject while also using the front-facing camera to snap photos.  It produces a full… read more

The Phone Oximeter - phone and sensor

LionsGate Technologies (LGTmedical), a Vancouver-based social enterprise, has secured its first major financial backers to scale up development of the Phone Oximeter.

This is an app and medical sensor that turns a non-specialist, community-level health worker’s smartphone, tablet computer or laptop into an affordable and simple but sophisticated medical-grade diagnostic tool that is typically only available, in the developing world,  in some hospitals.

Researchers at Massachusetts General Hospital in Boston have developed a system that can detect tumors by analysing a few thousands cells, sparing patients from the larger biopsies currently used.

The palm-sized device sits on the patient’s bedside table, operated through a simple smartphone app. At the core is a micro nuclear magnetic resonance (microNMR) chip, a scaled-down version of the technology found in magnetic resonance imaging (MRI) scanners. It… read more

Smartphone battery life could dramatically improve with new invention

September 16, 2011

University of Michigan computer scientists have developed a new “subconscious mode” for smartphones and other WiFi-enabled mobile devices that could extend battery life by as much as 54 percent for users on the busiest networks. It’s called E-MiLi (Energy-Minimizing Idle Listening).

Even when smartphones are in power-saving modes and not actively sending or receiving messages, they are still on alert for incoming information and they’re… read more

Smartphone brain scanner

Smartphone brain scanner

Researchers at the Technical University of Denmark have demonstrated a fully functional smartphone brain scanner — consisting of a low-cost 14-channel EEG headset with a wireless connection to a smartphone (Nokia N900) — enabling minimally invasive EEG monitoring in real-world settings.

The system provides a fully portable EEG based real-time functional brain scanner, sensors, data acquisition, logging, brain state decoding, and 3D activity visualization.… read more

Smartphone technology acceptable for remote stroke diagnosis

October 3, 2012

stroke image

A new Mayo Clinic study confirms the use of smartphones medical images to evaluate stroke patients in remote locations through telemedicine.

“Essentially what this means is that telemedicine can fit in our pockets,” says Bart Demaerschalk, M.D., professor of Neurology, and medical director of Mayo Clinic Telestroke.

“For patients this means access to expertise in a timely fashion when they need it… read more

Smartphone technology inspires design for smart unattended ground sensor

May 30, 2013

ADAPT_DARPA

DARPA’s Adaptable Sensor System (ADAPT) program aims to transform how unattended sensors are developed for the military by using a manufacturing process similar to that of the commercial smartphone industry.

The goal is to develop low-cost, rapidly updatable intelligence, surveillance and reconnaissance (ISR) sensors in less than a year, a marked improvement to the current three-to-eight year development process.

The unattended ground… read more

Smartphone training helps people with memory impairment regain independence

February 9, 2012

Baycrest  neuropsychologists have found that a smartphone training program, theory-driven and specifically designed for individuals with memory impairment, can result in “robust” improvements in day-to-day functioning, and boost independence and confidence levels.

“The goal of our study was to demonstrate the generalizability of our training protocol to a larger number of individuals with moderate-to-severe memory impairment,” said Dr. Eva Svoboda, a clinical neuropsychologist in the Neuropsychology… read more

Smartphone-based device could provide rapid, low-cost molecular tumor diagnosis

April 14, 2015

SmartphoneDiagnosis-ft

A smartphone-based device developed by Harvard Medical School investigators at Massachusetts General Hospital could bring rapid, accurate molecular diagnosis of cancer and other diseases to locations lacking the latest medical technology.

The device uses technology for making holograms to collect detailed microscopic images for digital analysis of the molecular composition of cells and tissues.

“The global burden of cancer, limited access to prompt pathology… read more

Smartphones more accurate, faster, cheaper for disease surveillance

March 14, 2012

Smartphones are showing promise in disease surveillance in the developing world.

Smartphone use was cheaper than traditional paper survey methods to gather disease information (after the initial set-up cost), researchers at the Kenya Ministry of Health and the U.S. Centers for Disease Control and Prevention, found in a study.

Survey data collected with smartphones also had fewer errors and were more quickly available for analyses… read more

Smartphones not so smart for learning?

distrators

Smartphones distracted students from school-related tasks in self-reported results of a one-year study of first-time smartphone users at a major research university in Texas.

“Smartphone technology is penetrating world markets and becoming abundant in most college settings,” said Philip Kortum, assistant professor of psychology at Rice and the study’s co-author. “We were interested to see how students with no prior experience using smartphones thought [smartphones] impacted their education.”

Smartphoniacs: Addicts of the Information Age

July 10, 2009

The top 10% of smart-phone users — the smartphoniacs — are the true addicts of the information age.

You might be a smartphoniac if you:

- Take your smartphone to the restroom
- Send messages while driving
- Sneak a look at your messages during a conversation
- Suffer from sprained or elongated thumbs
- Openly use your smart phone in inappropriate places, such as first dates

Smell cannon targets virtual reality users

April 2, 2004

A new “air cannon” device can track an individual, shoot an aroma directly at their nose, and leave the person next to them completely unaffected.

Advanced Telecommunications Research Institute in Kyoto, Japan developed it for directing evocative smells to people exploring virtual-reality environments.

The device tracks the person it is aiming at with a camera mounted on top, which follows the target’s eyes. Software on a PC analyzes… read more

Smell-o-Vision is finally here

April 1, 2013

Smell-O-Vision was a system that released odors during the projection of a film so that the viewer could “smell” what was happening in the movie.

Now the “smelling screen,” invented by Haruka Matsukura at Tokyo University of Agriculture and Technology in Japan and colleagues, makes smells appear to come from the exact spot on any LCD screen that is displaying the image of a cup of coffee,… read more
