User-Centered Design

User-Centered Design is creating for the specific benefit of users based on their needs.  It is essential to design because if a user finds the design difficult to understand/learn/use, then they will choose to not avoid using it if possible.  User-Centered Design ensures that not only is the design usable and understandable, but also that it relates to you.  This is prevalent on social media apps (such as how Facebook advertisements almost always are something you've been wanting or how Pinterest's feed adds in pins you might also enjoy) and music listening apps (for example, Spotify suggests music based on what you have been listening to).

 The Four Types of User Interfaces are:
  • Graphical User Interfaces
    • This interface is the visual aspect of a consumer interacting through graphic icons and visual aids - not just text.  This includes windows, icons, menus, etc.
  • Voice Interfaces
    • This interface is controlled by a person's voice, such as Apple's Siri or Amazon's Alexa or Window's Cortana.
  • Touch Interfaces
    • This interface uses touch screens for people to use them, such as iPads and smart phones.  
  • Command Line Interfaces
    • These interfaces require that the user has experience using this technology.  This refers to early stages of computers when users had to be taught how to use a complicated system.

Which Microphone to Use?

In what scenario should the following microphones be used? Handheld A handheld microphone is best for performers or news reporters.  They can easily handle the microphone, and it can capture their voice accurately, while avoiding picking up background noises. Lavalier The lavalier microphone is ideal for speakers who talk with their hands or hold props while talking, and therefore can not hold a microphone.  These also work great for actors who need their microphone hidden. Shotgun This type of microphone is best for filming a movie scene, positioned over people having a conversation. Boundary (or table) mic These microphones are often set on tables in podcasts or sit down style youtube videos.  Not only are they incredible effective, but also quite efficient because you can plug them into a laptop USB to easily record audio.

Field of View Variables

Four important variables to consider when composing your field of view are: Camera Location - The point of view (the position of the camera in relation to the subject) is obviously essential to the shot.  The physical location  needs to be paid careful attention to because it determines what is or isn't in the shot. Camera Angle - the angle of the camera is important because it influences the message of the shot and exaggerates different things in the photograph. Subject Location - this is not always up to the photographer but is just as essential to the shot.  The pose and also the landscape around the subject effect the image greatly.   Focal Length - this is the lens found on camcorders that gives you latitude to adjust your framing.  This helps zooming in and out and to adjust the frame and framing the subject.
