Blue eyes technology..document (1)
The document discusses Blue Eyes technology, which aims to give computers human-like perceptual abilities such as sight, hearing, and touch. This would allow computers to better interact with and understand humans. The technology uses sensors to identify a user's actions, physical and emotional states. It analyzes this information to help the user or perform expected tasks. For example, a TV could turn on when detecting eye contact. The goal is to create devices with emotional intelligence that can recognize and respond to human emotions during interactions.
Bluetooth
Bluetooth is a short-range wireless technology that allows data exchange between devices like phones, laptops, and printers. It was developed in 1994 and uses radio waves in the 2.4 GHz band to connect devices within a 10-100 meter range. Bluetooth devices can form ad-hoc networks called piconets to share data and voice signals. While convenient, Bluetooth has limitations like low data rates, short range, and potential security issues if not configured properly. It finds applications in wireless headsets, car infotainment systems, and wireless speakers. Future developments aim to improve bandwidth, reduce interference, and streamline connection setup while maintaining compatibility.
Hacking
Hacking involves gaining unauthorized access to computer systems or networks. It began in the 1960s at MIT and has been part of computing for 40 years. There are different types of hacking such as website hacking, network hacking, and password hacking. Hackers hack for reasons like fun, showing off skills, stealing information, or destroying enemy networks. While hacking can test security and help find vulnerabilities, it is generally illegal and can harm privacy or destroy data. Famous hacker groups include Anonymous, which opposes censorship through hacking government websites.
Zigbee abstract
Zigbee is a low power wireless technology standard developed as a specification based on the IEEE 802.15.4 standard. It was accepted by the Zigbee Alliance, a consortium of over 300 companies, in 2004. Zigbee devices can transmit data over longer distances by passing data through a mesh network of intermediate devices to reach more distant ones without a centralized controller. The technology is intended to be simpler and less expensive than other wireless standards like Bluetooth.
Mind reading computers
Mind reading computers can infer a person's mental states through analyzing facial expressions and head gestures with video cameras. They work by storing representations of how different mental states like thinking, agreeing, or being happy are expressed physically. Another method uses a headband that measures blood oxygen levels near the brain using functional near-infrared spectroscopy. While this could help people with disabilities, it risks privacy breaches and extracting confidential information. The accuracy of inferring thoughts is currently around 86.4% but the complexity of the human mind poses challenges to fully realizing mind reading computers.
Airborne internet-presentation(my)
Abstract
The word on just about every Internet user's lips these days is "broadband." We have so much more data to send and download today, including audio files, video files and photos, that it's clogging our wimpy modems. Many Internet users are switching to cable modems and digital subscriber lines (DSLs) to increase their bandwidth. There's also a new type of service being developed that will take broadband into the air. In this paper, we'll learn about the future of the Airborne Internet. We'll take a look at the networks in development, the aircraft and how consumers may use this technology.
Land-based lines are limited physically in how much data they can deliver because of the diameter of the cable or phone line. In an airborne Internet, there is no such physical limitation, enabling a broader capacity.
The airborne Internet will function much like satellite-based Internet access, but without the time delay. The airborne Internet will actually be used to compliment the satellite and ground-based networks, not replace them. These airborne networks will overcome the last-mile barriers facing conventional Internet access options.
This paper addresses some of the trends and issues involved in developing an Airborne Internet capable of achieving this goal. Understanding relationships between these trends and issues and the objectives and functional requirements of the program will allow various participants in this complex program to keep activities in proper perspective. The all-round development and improvement are the key areas of research work performed in this paper.
Silent Sound Technology
This document discusses silent sound technology, which allows people to communicate without making audible sounds. It works by detecting tiny muscular movements in the lips during speech using electromyography or image processing techniques. This information is then converted to electrical signals and transmitted as synthesized speech. The technology could help those who have lost their voice or have speech impediments to communicate over the phone or translate between languages. However, it faces restrictions for tonal languages and in differentiating between speakers.
Misuse of Internet
The document discusses the internet and its uses and misuses. It defines the internet as a worldwide network of interconnected computer networks that transmit data using the Internet Protocol. It notes that the internet allows people to communicate and share data anywhere in the world if they have access. Some key uses mentioned include communication with friends, online shopping, watching videos, and performing research. However, the document also lists several misuses, such as identity theft, piracy, cyberbullying, fake advertisements, pornography, hacking, time wastage, and negative impacts on family communication.

The technology uses electromyography to monitor muscle movements when speaking and converts them to electrical signals representing speech. Image processing also analyzes lip movements. Some applications include helping people who lost their voice and covert military communication. The technology could enable silent phone calls and transmitting PIN numbers securely. Overall, silent sound technology implements "talking without talking" and may have useful applications in the future.
Bluejacking
Bluejacking involves using Bluetooth to send unsolicited messages to nearby Bluetooth-enabled devices without consent. It exploits Bluetooth's ability to discover and display other devices within a 10-100 meter range. While initially only text, bluejacking messages can now contain images and sounds. The messages do not alter the recipient's device but can create minor annoyance. Researchers have studied bluejacking's potential applications if used positively, such as providing advertising or informational messages to people in public areas. However, others use it merely for amusement without permission. Proper user awareness and device security settings can help prevent unwanted bluejacking messages.

BLUEJACKING
Bluejacking involves sending unsolicited messages to Bluetooth-enabled devices using Bluetooth technology. It was first done by a man in Malaysia as a prank. Bluejacking works by sending a vCard containing a message in the name field to another Bluetooth device using the OBEX protocol. While mainly used to send messages anonymously, bluejacking could potentially be used for advertising, viral marketing, and location-based services. Preventative measures include turning Bluetooth off in public or setting it to non-discoverable mode.
Brain gate system document
The document provides information about the BrainGate system, which is a neuroprosthetic device that allows users to control external devices like computers with their brain activity. It consists of a sensor implanted on the motor cortex of the brain that detects electrical signals associated with movement planning. These signals are transmitted to a computer system via a connector on the skull. The computer analyzes the brain signals and translates them into commands to control a computer cursor or other devices. This provides a "BrainGate pathway" for users who have lost limb function to control devices with their thoughts. The system was developed by Cyberkinetics to help paralyzed individuals and represents an early application of brain-computer interface technology.
Bluejacking
Bluejacking allows Bluetooth enabled devices to anonymously send unsolicited messages to other nearby Bluetooth devices by sending a vCard file containing a message. While bluejacking does not hijack or gain control of the recipient's device, it can be seen as a violation of the personal space and privacy associated with someone's mobile phone. The document discusses the technology behind bluejacking, including how Bluetooth works and the vCard format, and conceptualizes bluejacking as a violation of the mobile phone as a possessional territory.
