Objectives: Post hospitalization care of a patient treated for critical illness, for instance cardiac arrest has been regarded as imperative. Nevertheless, it has become inevitable to skip follow-ups by the patients themselves. Method: This paper aims at designing a system which continuously monitors the health of the patient despite the patient being busy with his routine. An application is developed...
The rapid development of smart-phone technology in recent years has lead to many smart-phone owners owning out-of-date devices, equipped with useful technologies, which are no longer in use. These devices are valuable resources that can be harnessed to improve users' lives. This project aims at leveraging these older, unused devices to help improve road safety, specifically through the improved response...
Currently, personal assistant systems, run on smartphones and use natural language interfaces. However, these systems rely mostly on the web for finding information. Mobile and wearable devices can collect an enormous amount of contextual personal data such as sleep and physical activities. These information objects and their applications are known as quantified-self, mobile health or personal informatics,...
The advent of state-of-the-art telecommunication devices like smartphones has led to a considerable increase in the amount of electronic communication exchanged. While the improved availability increases personal flexibility—reducing rigidity in time and place of communication—it comes at a price. The ‘anytime, anyplace’-accessibility, which has become the norm in today's (working) society, can cause...
This paper discusses the design and development efforts made to collect data using an opportunistic crowdsensing mobile application. Relevant issues are underlined, and solutions proposed within the CHIST-ERA Macaco project for the specifics of collecting fine-grained content and context data are highlighted. Global statistics on the data gathered for over a year of collection show its quality: Macaco...
Ground transport infrastructures require in-situ monitoring to evaluate their condition and deterioration and to design appropriate preventive maintenance strategies. Current monitoring practices provide accurate and detailed spatial measurements but often lack the required temporal resolution. This is because the large scale of these infrastructures and the expensive equipments required for monitoring...
The ability to detect gunshots can provide someone with invaluable information in various circumstances. For the military and public servants, detecting gunshots can help save lives and potentially target offenders. People participating in shooting sports as beginners or professionals can also benefit from the use of sensors for improving their reaction and self control during training. Most current...
This poster presents a hardware/software solution, called On-The-Go Switch (OTGS), enabling a smartphone to control the connection state of a USB-attached device. Through an example, we show how OTGS can reduce the energy consumption of portable spectrum sensing platform utilizing low-cost Software Defined Radio. We show that OTGS can reduce the energy consumption by 47%, compared to a baseline, which...
In today's advancing ubiquitous computing age, with its ever-increasing amount of information from various applications and services available for consumption, the management of people's attention has become very important. In particular, the high volume of notifications on mobile devices has become a major cause of interruption of users. There has been much research aimed at detecting the opportune...
Smartphones have revolutionized the way infrastructure health monitoring applications operate. Their ubiquitous sensing and communication capabilities have made measurement data for infrastructural health monitoring applications easily available. They, however, also introduced a new challenge, namely the huge amount of data that is generated. This new reality prompts the need for efficient techniques...
Indoor Positioning is a crucial topic to provide autonomous services to people based on their location. Nowadays dominating positioning systems, like GPS (Global Positioning System), are designed for outdoor use not applicable for indoor scenarios as they depend on a direct line of sight to reference stations. Recent progress in wearable computing peaked in the promising development of SmartWatches...
While the traditional Visible Light Communication (VLC) system has attracted a lot of research attentions on boosting throughput, using Commercial Off-The-Shelf (COTS) devices, e.g. existing cameras on the smartphones, is a recent trend to implement readily deployable VLC systems. In particular, since LED-Camera VLC systems have shown a promising potential in large indoor communication due to the...
Human development is directly related to the transport facility. India has been starting its transport through railways since 19th century. The Indian railway system is very big and very complicated. When generation moves forward, the technology and complexity are also moves to its higher levels. Now days, there is no exact communication between Indian railways and passengers. When the passenger wants...
Today's life rolls around the concept of automation and the things that are automated are said to be of next generation because they reduce the interference of human beings. The home automation system technology is unique from other systems which give ability to the user to control the system from any location around the world through an internet connection. The existing system describes implementation...
According to the recent statistics about 7.5% of Indians are speech challenged and 5.8% of the population is hearing impaired and Indian Sign Language is the only mode of communication used by them. In this paper we have presented an approach that gives a technique for improving Sign Language Recognition system. In the proposed method; we will be using sensors which are incorporated on a glove to...
Mobile apps often collect and share personal data with untrustworthy third-party apps, which may lead to data misuse and privacy violations. Most of the collected data originates from sensors built into the mobile device, where some of the sensors are treated as sensitive by the mobile platform while others permit unconditional access. Examples of privacy-prone sensors are the microphone, camera and...
We demo VALERA, a Versatile-yet-lightweight Record- and-replay tool for Android. Record-and-replay is useful across the Android development lifecycle, from bug reproducing to systematic testing. VALERA uses a novel technique named sensor-oriented replay (recording and replay- ing sensor and network input, event schedules, and inter-app communication via intents) to achieve high accuracy and low overhead...
Road accidents rates are very high nowadays, especially two wheelers. Timely medical aid can help in saving lives. This system aims to alert the nearby medical center about the accident to provide immediate medical aid. The attached accelerometer in the vehicle senses the tilt of the vehicle and the heartbeat sensor on the user's body senses the abnormality of the heartbeat to understand the seriousness...
This paper demonstrates a new cooperative bus location system with BLE (Bluetooth Low Energy) devices and smartphones. Our idea has extended common participatory sensing systems to realize more practical sensing systems because common participatory sensing mechanisms require a participants' operation to measure some values. Our proposed system consists of a BLE devices on a bus, smartphone applications...
We look at the problem of using accelerometer in smartphones to detect mobility activities of users. The activities are internally composed of several simple activities. One can perform the task of distinguishing the activities using classic classification techniques with two different data representations namely, statistical features and ECDF-based features. Our recommendation in this paper is to...
