Abstract
Have you ever wondered why many devices that we use daily are so difficult to use? Why has no one designed a universal adapter for all the tools and equipment that use rechargeable batteries? If you’re anything like me, you could likely fill drawers with all the different adapters you have acquired for cellphones, computers and peripherals, BluetoothTM accessories, portable music players, cordless phones, drills and the like; not to mention all the remote controls for televisions, sound systems, and VCR, CD, DVD and Blu-ray DiscTM players. Consider for a moment: Have you ever owned an appliance or device that you particularly liked? Why did you like it? Was it was easy to use? Did it have intuitive displays, or labels that were easy to read and understand? Or did you simply like the appearance of the device – sleek, colourful, modernistic? Companies like Apple have led their competitors in intuitive design features with products such as Mac computers and the iPod. For many years, Apple has offered product lines that are interoperable, aesthetically appealing and intuitive to use. They have also recognized the importance of interoperability with competitors’ products.
