Bluetooth is used popularly in mobile phones, laptops etc. to share and transfer files with other devices in the vicinity.

It can be used for various other purposes such as to make gadgets wireless or cordless.

It is a channel for disseminating information.

Currently what is being used to interact with them? 

It is the direct manipulation of interface widget using a finger or a pen. But this limits the number of simultaneous collaborators with respect to how many people can fit around the display and also requires the display to be within the reach.

Keyboards and mouse could be used but that limits the use of the information display to a single user.

Similarly when the other techniques didn't work out, Bluetooth is the technology which helped.

The method for interacting with the large displays must be lightweight and should support the spontaneity with which a person may discover the space. The main aim was to facilitate spontaneous interaction with a public display without requiring the installation of additional software. To address the issue of interacting with large public displays at a distance the idea of BlueTone took birth.

BlueTone is a framework that supports opportunistic interaction with public displays using any Bluetooth enabled mobile phone.

to handle many different types of files.

- Suppose Person A wants a image or a ringtone that his friend may have. What initially

happens is that a software called P2PBluetooth is started on both devices.

- This softwares sets up a framework thats recognizable to both devices making it easier 

for file transfer

- Then another software called J2ME is used specifically for file transfers

- Then a series of functions are called to connect, secure, and transfer. These files are: 

- ConnectionManager is responsible for handling the connection of the system. 

Determines when somebody disconnects.

- P2PListener is like a server waiting to see what is expected from the bluetooth connection

- P2PPublisher manages the list of contents that people intend to share.

- P2PDiscoveryService helps find additional people to connect to

Some new Applications:

- I think making a safer traffic system using bluetooth connected to cars would be very effcient

- Using the proximity sensors, cars can automatically be turned on or your door can

automatically unlock

- Bluetooth could automatically pay our money when at the cash register

Bluetooth technology has recently become more and more popular among companies and personal users alike. One of the main attractions for companies today is that Bluetooth enables wireless connection without needing a line of sight connection. Bluetooth is a short-range radio technology that was originally designed to be low cost, low power, and a replacement for cabled technologies . The technology enables users to sap data and synchronize files without having to physically connect the devices together.

Before Bluetooth technology was used by shipping companies,the tasks involving their daily activities were usually very redundant. For example, instead of having peripherals communicating with each other automatically, companies had to hire extra help in order for some of the tasks to be done. These particular jobs include keying shipping data, package data,shipping routes, etc. into databases manually. It was not a difficult job at all, but it was a tedious task. Most importantly, it required shipping companies to contribute a massive amount of time to the process. As an operating rule of thumb, shipping companies live on time. Without the technology, drivers who might be considered some of the most important workers in the business are more in danger because of a lack of hands-free technology when they are on the road. These particular examples illustrate the need for a wireless technology for the package shipping industry. Therefore, many companies have selected Bluetooth wireless technology to help them improve their daily business operations. The purpose of this study is to explore the implementation and application of Bluetooth technology in the shipping industry.

•  Remote patient monitoring
•  Wireless biometric data
•  Medicine dispensers 

Travel: With a personal device that employs Bluetooth wireless communications, a traveler might check in using this device, which could include personal identity credentials, thus eliminating the need to insert a card into a terminal. Moreover, an electronic boarding pass could be issued and stored in the Bluetooth device; that same device could then be used to wirelessly present the boarding pass when boarding the aircraft, eliminating the need for a paper boarding pass.

Home Networking:

•  A mobile phone could be used as a cordless phone via a Bluetooth voice access point (base station)
•  Portable computers could be used at home through wireless dial-up networking or a data access point

Smart tags:

This can be attached to anything we like and it will communicate with your phone, allowing your phone to keep a track of it's location. Your keys will never get lost.

Similarly we have Bluetooth stickers too

Bluetooth devices will connect to each other when in proximity to prevent crashes and apart from that the authority knows where the traffic is being jammed instantly
