MY LOCATION NOW
My Location Now systems are able to determine users’ locations.These applications have a strong areas as to tell where one finds how best is to get to their dimensions,whether friends are nearby,what is the local weather forecast,nearby company packages findings..
When its about mobile industry,LBS is the main feature which makes a difference between mobile device and traditional fixed devices.
Use of this navigation system grown slowly because of weak economy and investment priorities for potential users.Others include security and privacy concerns.Vendors are working to solve these issues.
Your current location is:
My Location Coordinates and GPS-Augmentation
As because location coordinates work with low power signals,these donot penetrate into buildings and other hurdles to avoid interferences with ground based radar signals.This feature limits the accuracy of that positioning system.To solve this issue LBS devices augment GPS with regional local and national Differential GPS Systems. “The Wide Area Augmentation System” is used in Western Countries.Where these systems coincide with ground based signals where exact location is prexisting. By giving the measured inaccuracies of GPS readings hence providing more accuracy
LBS’market value;
Major telecommunications providers use navigation worldwide. Various companies sell GPS devices for navigation. Many software vendors like Google possess location related applications that give navigational access. Many manufacturers are known , i.e “Nokia “and “Research in Motion-sell” mobile phones.
Global Positioning System
LBS is based on GPS.Mechanism include low power,ultra high frequency radio signals.When we ON the
GPS mode of cell phone or vehicle or any other host, it gets connected to three or more satellites.These
satellites through triangulation use ,based on its distance and direction from satellite ,analyze location
by factors such as signal timing and strength.
Triangulation through Cellular data or Wifi
Cellular data systems use triangulation through distance of phone from cell tower to which it is connected.Likewise wireless systems also provide location of a device by measuring its distance from Wifi access point,consequently signal strength.Systems can find locations by themselves, or to gain accuracy,these communicate with each other.Then service providers proceed the process on servers or now a days powerfully through mobile processing.Some examples include Skyhook,Apple’s iPhone etc.Skyhook uses navigation system through triangulation without using GPS.Other companies have also that approach.For example my location google maps for cell phones.Google has also introduced triangulate that uses Wifi signals. GPS and wifi combined give faster readings than using only GPS as source of location monitoring. Skyhook is working with chip makers for mobile devices for more beneficial access. Several issues, for instance security and privacy concerns has limited the location based services.
The implementations
Some software companies have formulated applicaions that work with my current location coordinates.For example “Xora’s GPSTimeTrack” business productivity application ,allows to determine route of drivers and monitors efficiently.
“AT&T “offer these applications which work with GPS system on devices or GPS enabled phones. “Loopt” works with QPoint’s location-based server software and this allows to find where friends locate
around on an online map.Developers use “my location now” Google map free service to connect to
company’s location forms.
Now a days popular system include LBS and mobile Web browser.
Slow adoption resulted due to LBS’s ability to easily find where am I right now, which lead to privacy
related issues.
Although LBS is multiworking application
LBS and business insights;
Information diffusion across customers through LBs plays vital role in popularity of businesses.The multiple features of a business,i.e social influence,geographical proximity,customer preference,and content, these all influence the popularity of a business.
The businesses that are highly influenced by geographical proximity ,attract local customers in the city. A geographical proximity access the location of customers visiting a business unit.Visitor is either local visitor or foreign visitor.A business may get both types of visitors.A business is known aslocal dominated if the majority of the customers are local and vice versa.
Location and tourism
Location map is popular recommendation for a new visitor to certain or unknown place.This is a faster method of communicating with a cultural or regional different atmosphere.However wondering is locally accepted method of familarity with a new place of visiting. Navigation systems possess the roads and footpath areas for navigation while there exist some of places which donot sound safe for travel or visit,this is not recognized by these location determining systems which requires the system to be more advanced. In emergency situations location applications have a devastative role which can not be denied.As the world is going to be a global village,which requires the navigation process advancement,privacy protected built in setup.
Location and Language learning ;
In many English as a foreign language (EFL) contexts, learning is often limited to decontextualized classroom learning, and students suffer from lack of interaction and opportunities for language learning. One of the recent emerging technologies, context-aware augmented reality (AR) technology can solve problem for EFL contexts. In the present study, 40 college students created scenes of gamified digital stories on a location-based AR app and shared them with other students. This study investigated how the students used the physical context and properties in their scenes and how the technology facilitated language learning.
Data were collected from student learning outcomes, post-surveys, and reflection papers. The results showed that the students employed context in three different ways, a real place, a fictional setting and a blended reality, and then integrated it with their content and transformed it into a co-constructed meaning-making site. The study also discovered that the technology supported the students’ language learning in the affective, cognitive, and social domains. All elements found in the three domains were interrelated and ultimately contributed to student learning.
Why my phone is awake?
Despite location based application’s popularity in recent years, smartphones and devices are and will remain limited by their battery life and energy consumption. Preserving this critical resource has driven smartphone OSes to undergo a paradigm shift in power management by default every component, including the CPU, stays off or in an idle state, unless the app instructs the OS to keep it on! Such a policy encumbers app developers to explicitly juggle power control APIs exported by the OS to keep the it on, during their activity by the app and off when no use. The resulting power programming unavoidably gives rise to software energy bugs on smartphones called no-sleep bugs, which is due to mis-handling power control APIs by apps and results significant battery consumption.
Some advancements towards understanding and automatically detecting software energy bugs on smart devices.These make following three contributions: (1) These present the comprehensive study of real world no-sleep energy bug features; (2)These propose the automatic solution to detect these bugs based on the classic reaching analysis algorithm; (3) These provide experimental data showing that tools accurately detected all 17 known instances of no-sleep bugs and found 34 new bugs in the 73 apps examined according to an experimental work.

“Feedback is considered an essential element of the computing systems in the HCI literature for helping people to account their privacy. However,the success of online social networks and commercial systems for mobile navigation which do not include feedback would seem to call the importance of feedback into question. We examined this issue in the context of a mobile location sharing system. Specifically, we report on the findings of a field de-ployment of Locyoution, a mobile location sharing system.
In our study of 56 users, one group was given feedback in the form of a history of location requests, and a second group was given no feedback at all. Our major contribution is to show that feedback is an important contributing factor towards improving user comfort levels and allaying privacy concerns. Participants’ privacy concerns were reduced after using the share my location mobile app system. Additionally,our study suggests that peer opinion and technical savviness contribute most to whether or not participants thought they would continue to use a mobile location technology”as stated by a reporter.

Forced resettlement;
For instance Germany has noticed an influx of forced migrants in recent years. Promoting social interaction with the local community is one of the reason for supporting the resettlement of newcomers. Free Location-based services present great benefits due to freecycling’s potential social engagement and location-based services’ ability to adapt to the user’s privacy. While,their working to support forced migrants’ resettlement is yet to be investigated. They conducted needs assessment interviews with 11 participants in Münster, Germany and analysed the results to develop user requirements for live location free services and then acquired a subset of the user requirements as a prototype mobile app called Geofreebie.
The evaluation of the app with 22 participants showed that Geofreebie offered two key advantages for forced migrants’ resettlement: it increased their social network, and created a sense of community on their side. This approach can benefit influencers and developers of location-based services to support forced migrant resettlement.
Maping and Citizen Science;
Community Mapping and Citizen Science involve the public in projects to acknowledge realworld problems such as air pollution,noice pollution or other required developments in their surroundings. Many of these are mostly location-based and maps play a vital role for engagement. Most importantly, they can be tailor-made to display information required by the drivers of these projects,different people with different interests.
Earlier Community Mapping and Citizen Science projects allowed the public to access data for use on such maps through web based systems. However, mobile devices possess additional sources of data collecting mechanisms and their in-built sensing devices i.e GPS) which allow users to work with additional types of information not available on web-based systems.
Although most of such Applications are known and working, experiences with community groups shows that flexibility is key of the groups themselves must be able to figure out what information they are searching for. While it is attainable to meet this need by developing a bespoke App for every group, many of the group members involved in such projects are not programmers and do not have funding for bespoke development.
Navigation at home;
Mobile location-sharing technology is greatly being used by parents to find the live location of their children. Research shows that these technologies may compromise to user values such as privacy and responsibility, while they work to promote others such as family security. As a solution, the use of Social Commitment (SC) models for governing the sharing and receiving of data proposed.
A social commitment represents an agreement between two people about which data should be shared and received in which situation and which is not to be. The use of SCs in mobile location sharing applications gives improved support for users privacy and responsibility as it works for a more flexible, context-aware location sharing methodology.
This section finds its application for primary school children (n=34) as the main target group, who’s values may be enhanced and secured through the use of location-sharing technology.If we provide children were with two versions of a mobile location sharing app: one with basic check-in functionality –the basic app –and one augmented with an SC model, which is known as a Socially Adaptive Electronic Partner ( saep). The more favourable result among other things will be that the saep would provide improved support for children’s values compared to the basic app
Location and public health;
Health promotion campaigns worked for increasing the use of the COVID Safe app should focus on promoting how the app will help out for contact tracing to return to ‘normal’. Moreover, health promotors have to address the app’s involvement in privacy, people’s lack of perceived need for this app and technical resistances. The novel coronavirus (COVID-19) has made its way around most of the world with each country having different levels of success and overcoming its spread. Contact tracing, alongside border restrictions,lockdowns,social distancing are all parameters that have contributed to control of COVID19.1 If the majority of contacts of a confirmed case are finded then the whole community transmission can be controlled.
However, the identification of contacts can be challenging because contact tracing relies on one’s recall. Digitally contact tracing, or contact tracing through digital means can improve the speed of contact tracing. The frequent quarantine of close contacts would lead to the control of an outbreak if the quarantine of contacts is complete and immediate. . Digital contact tracing should augment manual contact tracing, as it may help to find out the unidentified cases that can contribute up to 10–15% of cases overall. The COVIDSafe app was developed by the Governments as a public health initiative with the potential to contact tracing by helping to increase the completeness and speed of close contact finding to control the spread of the illness effeciently.
For instance as of early June 2020, only 24% of the Australian population had downloaded the app (6 million downloads), which is less than the estimated 56–95% population uptake required for it to be useful. The app works by the user downloading and registering basic information to which an encrypted reference code is opened for the app on the particular device being used.The app then uses Bluetooth app to find for other devices that have the COVIDSafe app installed and shows a ‘digital handshake’ when contact concides.
When contact with another person using the app is made within the range of approximately 1.5 metres,an encrypted reference code of each device and the time and proximity of the corresponding contact is then securely encrypted and stored on each person’s mobile phone. The app continues further to check for new connections every minute to determine the whole duration of contact with another person with live location,those noted as having contact for 15 minutes or more are considered as close contacts.
