Computer Organisation 1 Sébastien Piccand Input devices

Keyboards Pointing devices: Mouse, joystick... Audio: Microphone, MIDI Imaging and Video: Webcam, scanner, Fingerprint scanner... Other: game controller, remote control Haptic devices

Keyboards Used to enter commands/text/numbers in the computer One code per each key/combination of keys Can be cordless

Keyboards Layouts Inherited from typewriters Standard 102 keys: Contains letters, digits, punctuation and special keys (system keys, delete, tab, end, compositing keys...)‏ Extended with functions keys/multimedia keys Language dependent: Qwerty, Azerty, Qwertz Optimized for minimum efforts: Dvorak

Keyboards Layouts

Input devices Keyboards Pointing devices: Mouse, joystick... Audio: Microphone, MIDI Imaging and Video: Webcam, scanner, Fingerprint scanner... Other: game controller, remote control Haptic devices

Pointing devices Gives information in 2D space (x,y) coordinate Resolution (in cpi/dpi): gives the speed Selection buttons Purpose Drawing Moving cursor Quick access to mostly useful options (open a file, copy, get info,...)‏

Pointing devices: mouse Can be cordless Different technologie Mechanical (ball)‏: ball rotates two wheels Optical (LED or Laser)‏: compare pictures

Pointing devices: mouse Number of buttons 1: Apple 2: standard PC 3 or more Scroll wheel Degree of freedoms Normally 2 (x,y)‏ Can add z, plus rotation (for 3D objects)‏

Pointing devices: trackball « Reverse mouse » The base does not move but contains a ball that can be rolled

Pointing devices: joystick Stick mobile on a base

Pointing devices: touchpad Replaces the mouse on laptops Rectangle delimiting (x,y) range Can contain special areas for special keys/scrolling

Pointing devices: pointing stick A.k.a trackpoint, trackstick,... Little stick included in the keyboard of some laptops (Thinkpad, Dell,HP...)‏

Input devices Keyboards Pointing devices: Mouse, joystick... Audio: Microphone, MIDI Imaging and Video: Webcam, scanner, Fingerprint scanner... Other: game controller, remote control Haptic devices

Audio input Used to record sounds Voice: microphone Music: microphone, MIDI instruments‏

Audio input: microphone Record any sound Can be cordless Can be used with a speech recognition software to enable sending commands to the system

Audio input: MIDI instruments MIDI: Musical Instrument Digital Interface

Audio input: MIDI instruments MIDI data consists of notes characterized by: Pitch (height of the note: e.g. C#)‏ Start Sustain Release Instruments defines the timbre

Input devices Keyboards Pointing devices: Mouse, joystick... Audio: Microphone, MIDI Imaging and Video: Webcam, scanner, Fingerprint scanner... Other: game controller, remote control Haptic devices

Imaging and Video Used to grab pictures or videos Scanner: fixed images Webcam: videos Can be used with pattern recognition softwares to send command e.g. Fingerprint reader... to send position e.g. Eye tracker

Input devices Keyboards Pointing devices: Mouse, joystick... Audio: Microphone, MIDI Imaging and Video: Webcam, scanner, Fingerprint scanner... Other: game controller, remote control Haptic devices

Other: game controllers

Mostly button based + pointing device Joystick, Joypad Specialised game controllers Wheel + pedals, Yoke (aircraft), light gun Wii: motion sensor (3D accelerometer), position (infrared)‏ Force feedback information Mostly rumble

Other: remote control Like a cordless keyboard Usually keys for multimedia Uses infrared

Other: gloves Buttons on the top Position of the glove in space Bending of fingers Motion tracker Examples P5 glove (USB)‏ Power Glove (Nintendo)‏

Input devices Keyboards Pointing devices: Mouse, joystick... Audio: Microphone, MIDI Imaging and Video: Webcam, scanner, Fingerprint scanner... Other: game controller, remote control Haptic devices

Gives reality like feedback information Allows better immersion in a virtual environment Application Games Virtual reality Medicine Teleoperators and simulators

Haptic devices Type of feedback information Weight of objects (if moving them)‏ Inertia (flight simulator)‏ Density of objects (soft, hard)‏

Haptic devices Sensable application-gallery.htm application-gallery.htm application-videos.htm application-videos.htm Haptic community tro/gallery/index.html tro/gallery/index.html

Summary Input devices Keyboards Pointing devices Audio Graphics/Video Others Haptics
