Chapter 12: Audio Production

    Sound involves pressure and vibration to create a sound wave that travels to our ear. Amplitude is how far in between the crest and the trough of the wave is. Amplitude is measured in decibels. Frequency is how low or high the pitch is.

    Microphones are useful for recording sound so that it can be replayed back. Microphones convert sounds that are recorded through transduction. There are many different types of microphones. Some microphones are hand-held, some are lavalier, some are shotgun mics, and there are boundary mics.

  • Dynamic Microphone
  • Condenser Microphone
  • Moving-Coil Microphone
  • Ribbon Microphone
  • Condenser Microphone
There are also different types of pickup patterns:
  • Omnidirectional
  • Bidirectional
  • Unidirectional
Some reasons to use an external mic include being able to choose your mic, the sound being equal, and you have better control over your sound. Headphones also help when checking sound, and making sure everything sounds good.

Chapter 4: Visual Communication

      Visual communication investigates the passing of information in a visual form. Content is the tangible version of the stories and information we share with others. Form is the way that the content is designed and delivered. Applied aesthetics are informed observations and judgements made based off a set group of guidelines.     The elements of design are space, dots, lines, shapes, form, texture, pattern, and color. The principles of design are unity (proximity, alignment, similarity, and repetition), emphasis (contrast, color, depth, and proportion), perceptual forces (balance, continuation, figure-ground, and psychological closure).

Chapter 10: Photography

    Photography is capturing an image through light. Photography can be done on film or digitally. The lowest level camera is a point-and-shoot. Other types of cameras include DSLR's which are prosumer digital cameras, and video cameras. For the cameras, especially DSLR's, there are many different types of lenses including: wide-angle, telephoto, macro, fisheye, and super-telephoto. The different parts of a camera lens are the iris, shutter, and image sensor.       For a digital camera to take a picture it must be exposing the image sensor to light. The exposure triangle is made up of the three components of a camera, aperture, ISO, and shutter speed. The white balance fixes the coloring of the camera to match more to what we see everyday. Focus controls the sharpness of an object in frame. Depth of field is the area that is in focus, and can be shallow or great depending on how much you want in focus.

Chapter 6: User Interface Design

      A user interface is a system that supports HMI or a human-machine interaction. The types of user interfaces include: Graphical User Interfaces, Touch Interfaces, Voice  Interfaces, and Augmented Reality. The components and features of a user interface are: Navigation (primary navigation, secondary navigation, menus, accordions, and tabs).      There are many different ways to organize content. You can use thumbnails, carousels, pagination, and archives. The two types of tailoring are personalization and customization. Personalization uses previous actions to predict what you would want. Customization involves intentionally chosen content instead of prediction.      For an interface to be usable, it must have good learnability, efficiency, memorability, error management, and satisfaction. To know if the interface is usable, usability testing may be done. It is also important the the interface is usable and accessible to anyone with ...
