DSLR (Digital single-lens reflex) camera

combine the photographic quality of a single-lens reflex camera with the flexibility of digital technology

- Speech recognition technologies record, map, and analyze voice patterns. - Voice frequency, pitch, speech rhythms, and other characteristics are charted and compared to existing records.

how do voice recognition technologies work?

The scanner uses a laser that is reflected by the mark made by the #2 pencil, and this reflection is "read" by the scanner.

how does an OMR work?

capacitance

most touchpads use a _________ system to track finger movement across the touchpad

virtual

nearly all phones and tablets use ______ keyboards on a touchscreen

QWERTY keyboard

the most common text-entry input device for computers

1. static method - signatures are written on paper and then scanned. The software then maps the signature. 2. dynamic method - uses a stylus and touchpad. This method maps the signature and also measures pressure, pen angle, pen up/down, speed, and so on.

what are the two main signature technology methods?

- Optical character recognition (OCR) - like document scanning technology on steroids - OCR allows any text, even handwritten scrawls, to be digitized

what does OCR stand for, and what does OCR do?

- Radio frequency identification (RFID) technology - uses radio waves to transmit data to a scanner

what does RFID stand for, and how is it used?

- Near field communication (NFC) is a wireless technology with a short transmission range that is included in new smartphones and other devices, including tablets and home appliances. -used for smartcard identification, digital wallet payments, transportation tickets, and other instances where short-range data transfer is needed

what is NFC, and what is it used for?

used on checks so that they can be processed quickly by cashiers and banks

where might you see MICR technology used?

MEMS (microelectrical-mechanical system) chip

which chip is housed in cell phones and hearing aids?
