CGS 2060 (Input Section)
Optical/Digital Zoom
2 ways to focus on distant objects
Active Pixel Sensor
APS CMOS; digital camera in smart phones
NFC
Commonly used short-range wireless technology used for data transfer and electronic payments
Voice/Speech Recognition
Frequency, pitch, speech rhythms and other characteristics are charted and compared to existing records
Mouse
Mac developed this
Touchpad
Most of these use capacitance to sense when a finger has moved across the pad
Radio Frequency Identification
RFID stands for
GoPro
Rugged, water-resistant video cameras that allow users to film high definition video under harsh conditions (ski, ocean, high altitudes); extreme-action video camera
Active Pixel Scanner
Smartphone cameras work by focusing incoming light onto this type of array that captures images
Dynamic Signature Recognition
Using a stylus and touchpad to map signature and measure pressure, pen angle, pen up/down, speed, etc
Smartboard
a combo of input and output device that allows users to interact with large computer displays that is found in classrooms; interactive whiteboard
MEMS Chip
allow cell phone microphones and hearing aids to be so small
Webcam
camera that take photos or steams video into a computer or over the Internet
Input Devices
facilitate getting data and info into your computer
Smartphone
input device is a touchscreen or a keyboard
Laptop Computers
most of these come with touchpads
MICR (Magnetic Ink Recognition)
most seen on checks
Virtual Keyboard
most smartphones/tablets produced today
Resolution
number of pixels in an image
Bluetooth
provides short-distance wireless communication between electronic devices using low power radio signals
Optical Zoom
resolution remains the same when this is focused on distant objects
MIDI
technology allows musicians to create written sheet music simply by playing an instrument
Video Conferencing
technology that uses cameras, microphones, displays, speakers, and software to allow users to both see and hear each others
Optical Character Recognition
the technology that allows any text, even handwritten scrawls, to be digitized
OMR Technology
uses the reflection of a laser of the graphite left by a #2 pencil to determine if a bubble has been filled in
