Apple Trackpad

History
The idea for Apple’s trackpad was inspired from the success of multi-touch technology in Apple’s IPhones. The first Mac device to incorporate a multi-touch trackpad was the MacBook Air in 2008. It supported the use of multiple fingers to control various aspects of the user interface. Today, multi-touch technology can be found in all of Apples trackpads.

Use and Simplicity
The Apple trackpad is very straightforward to use. A person with no prior experience can learn to use the trackpad in as little as 10 minutes. Apple conveniently provides a step-by-step guide on how to use all the features of the track pad located under the “System Preferences” tab.

Benefits
  • Students can use two fingers to pinch the screen to zoom in or out, which would help those who have trouble reading small print
  • Students are able to simply tap the track pad, as opposed to using one finger to click a normal mouse.
  • Stylus
    • If students have poor motor skills, but can hold a pen, they can use a stylus with the track pad
    • Students are able to scroll if reading online, (System Preferences -> General -> Show Scroll Bars -> Always)
    • There are programs that can be downloaded, where students can draw or write…would help if paper is difficult to use or gets in the way.

  • Track pad functions can be changed to meet the needs of students with varying disabilities…specifically those with vision disabilities or issues with motor skills.

User Demands

  • In order to use most of these tools, the user must have relatively good fine motor skills. Using these tools requires a lot of finger movement and dexterity. People will disabilities such as arthritis, tourettes and other tics, Parkinson's, amputees, and Symbrachydactyly (pronounced simbra-kih-dact-ily) may have a hard time using the trackpad if the disability affects their fingers.

To Conclude...

Pros
  • The trackpad is user friendly. Many users try to use the same controls on other computers as they do with Apples trackpad due to its simplicity.
  • The trackpad adds an organizational dimension to users desktop, allowing them to glance over all open tabs, documents, etc. while searching for something in particular.
Cons
  • Problems may arise in individuals with certain disabilities restricting motor function in the hands such as: Symbrachydactyly, amputees, arthritis, Parkinson’s, etc. However, some conditions may be negated with the use of a stylus pen in conjunction with the trackpad. A lot of the tools have similar gestures (swiping with three or four fingers), making it difficult to remember which gesture applies to each tool. At $69, having a track pad for every student might not be financially plausible.
