It is very difficult to judge when a person is happy. The current way of estimating is to take a survey. However, surveys are prone to failure and they are not very exciting for the surveyors. The people surveyed make a best guess of questions, based on recall. One of the toughest surveys is to…

Interesting work by scientists at Microsoft that shows that using mobile phone social contacts is strongly correlated to the perceived mood. They have designed a mobile application that enables collection of immense amount of data of user interaction with the phone and parameters such the number and time of calls made, the SMS sent and…

Researchers at University of Urbana-Champaign found that productivity of workers increased in a coffee shop environment that was not too loud or not too quiet. There is an interesting NY Times blog describing the effect. Interestingly a group of people have taken that to create an app that plays the recorded background noise back, with…

Android combined with some electronics has been used much more than just a Google phone. For example see the video below to see how it has been used to control a remote control car over the Wifi network. {youtube}n6ypGlTCbKk{/youtube} What is interesting is that the phone has become an enabling electronic gadget since so much…

Mobile and healthcare has been abbreviated to mHealth and there has been significant amount of work that is being done to make mobile applications that will work in the healthcare space. The applications in the iPhone app store vary from not so useful “Anti-mosquito” and “White noise” to more useful ones like Pedometer and Calorie-counter…

Several companies want to make applications and they go about dedicating several resources to create the application. We, at Usinlife have thought about what makes a good application and have three basic guidelines. These are not the only guidelines but are the starting point for every app process. 1. The app has to fulfill a…

Electrocardiogram (ECG) has typically been done with an 12 lead device that measures the change in voltage at different terminals. This machine is rugged and sensitive to other signals. However, disruption of this technology is happening from small iPhone based devices that record ECG using just two sensors that are placed behind the phone. A…

Usin’Life is working on developing a mobile applications for fluorescence spectra observation. Typically, the android market has several applications that show the spectra but they are very company specific. This makes a user struggle to find the spectra of interest. If they have access to the computer then one way to do this is to…

This is work in progress since a mobile phone with terahertz capability does not exist yet but could potentially be very useful. Terahertz waves are those in the electromagnetic spectrum that are between millimeter waves and infrared, with frequencies between 0.3 to 3 Terahertz. Currently the technology to generate and analyze them do not exist…

Keeploop has an interesting idea on combining an additional lens and LED into a compact device that is attached magnetically onto the back of the phone on top of the camera lens in a mobile phone. This increases the magnification of the phone lens and also enables to work in a macro mode. This macro-lens,…
