Performance Load: Q4 Examples

Contact-less Payment

Contactless Payment

 

Figure 1.

Contact-less payment options, otherwise known as Paypass or Paywave, reduce both the kinematic and cognitive load involved in paying for items via card. The kinematic load is reduced as the user does not need to swipe their card or move their fingers in order to enter their pin. The cognitive load is reduced as the user does not need to remember their pin in order to purchase an item.

 

Contents Pages

Contents Page

Figure 2.

Content pages reduce cognitive and kinematic involved when searching for a page in a book. The cognitive load is reduced as readers do not need to scan the pages of the text or remember what information is on each page – it is already displayed for them. The kinematic load is reduced, for hard copy texts at least, as the reader doe not need to turn each individual page searching for their desired content.

 

Calculators

Calculators

Figure 3.

Calculators reduce the cognitive load associated with calculating math problems. The user does not need to remember math principles and theory in order to work out a problem, or remember the digits involved. Instead, the calculator can remember the digits in the precise order and solve the problem.
