ABSTRACT

Blindpath identification with the help of RFID technology not only makes the blind can gain feelings oforientation during walking, but also has the knowledge of the exactly location of the street. The main idea isthat when a blind man walking on the path which has electronic tags pre-built under the tile of the blind

path, those tags activated by radio wave came from the RFID reader sent their identity codes transmitted bythe reader to the computer, and after the query of the database, the number of the street, the name of theshop of the current location of the blind will be known immediately, meanwhile, the corresponding voicedata will be sent via earphones to the blind in order to get the precise identification. The system iscomposed of the hardware and software. The hardware includes the electronic tags, reader, MCU, wirelessearphone and GSM circuit. The software is consisted of the database that controls the read-write of the tags,the management of the street info as well as the sending of the voice data. Experimental result shows thatthe system almost can achieve the proposed objective and provide the novel technology support for theblindpath construction.

ABSTRACT

A location and tracking system becomes very important to our future world of pervasive computing, whereinformation is all around us. Location is one of the most needed information for emerging and futureapplications. Since the public use of GPS satellite is allowed, several state-of-the-art devices become part ofour life, e.g. a car navigator and a mobile phone with a built-in GPS receiver. However, location informationfor indoor environments is still very limited. Several techniques are proposed to get location information inbuildings such as using a radio signal triangulation, a radio signal (beacon) emitter, or signal fingerprinting.Using radio frequency identification (RFID) tags is a new way of giving location information to users. Due toits passive communication circuit, RFID tags can be embedded almost anywhere without an energy source.The tags stores location information and gives it to any reader that is within a proximity range which can beup to 10-15 meters for UHF RFID systems. We propose an RFID-based system for navigation in a buildingfor blind people or visually impaired. The system relies on the location information on the tag, a userpsilasdestination, and a routing server where the shortest route from the userpsilas current location to thedestination. The navigation device communicates with the routing server using GPRS networks. We build aprototype based on our design and show some results. We found that there are some delay problems in thedevices which are the communication delay due to the cold start cycle of a GPRS modem and the voice delay

due to the file transfer delay from a MMC module.

Mobile Device Programming for Finding Optimal Path on a Fast-BusSystem

ABSTRACT

In this project, we developed a real-time software solution that helps users to find the optimal combinationof routes in a bus-based passenger mass transportation system, TransMilenio (TM), in Bogota, Colombia.The TM users face the need to choose the best route between two points, and the information presented, in

form of maps and operation hours for each route, usually is not enough to make that choice. Even if a usercould have all the information about the system, the decision would not be trivial. Also, there is not a uniqueway to define the optimally criteria, since besides total travel time, the user might want to avoid changingbuses which might involve long walks in the stations, or avoid congested routes to increase the chance offinding an available seat. This paper describes the problem faced and the proposed solution

ABSTRACT

The use of mobile handheld devices is expanding rapidly both within the business and individual context.

These devices are now essential tools that offer competitive business advantages in todaypsilas growingworld of ubiquitous computing environment. The technology advancement has made it possible to embedmore facilities in mobile phones. While they provide benefits, they also pose new risks on security either bythe information they contain or information that they can access remotely. Secure cash transaction is ofserious concern in growing use of cash cards and internet transactions. Cash withdrawal cards, chip and pinfacility is one of the facilities which have increasingly been used for business and social activities. However,there has been limited research focus on security and flexibility. This paper will introduce the concept ofphysical browsing and development of a system that will allow users to use their mobile phones to securelywithdraw cash from ATM machines. The paper presents the architecture for the M-Cash withdrawalapplication and relevant technologies and security issues have been presented and relevant procedures andsteps for fully implementing the application have been analyzed.
