Appliance Design - September 2008 - (Page 21) INDUSTRIAL DESIGN & HUMAN FACTORS efficient power ity, as innovations in technology drives the growth in features and complexity. In reality, we have seen some products that utilize technology to improve usability, such as the Apple iPhone, and others where technology gets in the way of usability, such as BMW’s original in-car iDrive system (currently going through a relaunch with significant design improvements). But, the difference between the iPhone and the iDrive is not one of complexity, at least in a technical or functional sense of the word. If you calculate the number of options and actions supported by both the iPhone and its similarly named automotive foil, they are roughly equivalent in their complexity. The usability differentiator between comparably featured products is not simplicity versus complexity, but clarity, the users ease of perceiving and interacting with the provided functions. The iPhone delivers clarity in a number of ways, most notably via direct manipulation of the interface — touch to open, pinch to reduce size, and so forth. The iDrive failed to be effectively clear, in part because it requires significant coordination between spatially separated tactile (controller) and visual (display) interaction points — all while competing with a driver’s already The Flip Video Mino took the unconventional approach of reducing features to improve ease-of-use.

Our backward curved fans provide up to six inches of steady static pressure. Both operate 15-20% more efficient than traditional AC fans with VFD. They’re ideal for main-secondary or pressure control, and RS485 networks. Put the power of Rosenberg EC fans to work for you.
