Usability Quote of the Day

May 23, 2012

There's something very odd going on here. If designers made completely unrealistic assumptions about the physical world when designing technology, then we would blame them (and likely sue them) for technical incompetence. Yet when they make grossly unrealistic assumptions about human nature... we don't blame the designers, we blame the unfortunate people who are just trying to do what the design requires. -- Kim Vicente, The Human Factor, p. 45.    (via interaction-design.org)

Razer Copperhead Hands-On Preview

A new mouse created a better User Experience with a lot of versatility ...

"Aesthetically, the new mouse features a new wraparound lighting system and a Razer logo that pulses with light. The mouse will be available with three different color lights: tempest blue, anarchy red, and chaos green. At a future date, Razer also hopes to offer different case styles for a nominal cost. Possible styles include translucent and camouflage-colored cases. The Copperhead closely resembles the Diamondback in shape, but the real differences lie under the hood.

The new laser system samples at 1000Hz. The polling rate results in a 1ms response time. In comparison, conventional mice poll at 125Hz for a response time of 8ms. You will be able to adjust the USB polling rate to 125Hz, 500Hz, and 1000Hz. Likewise, you can change the mouse's dpi setting to 400, 800, 1600, and 2000. In addition to providing the usual mouse sensitivity adjustments, the Copperhead will let you adjust the sensitivity along each movement axis independently. This means you can adjust the mouse to move very quickly along the x-axis and slowly across the y-axis. As with the Diamondback, you can make sensitivity adjustments on the fly with the click of a button.

In addition to the usual left, right, and clickable wheel buttons, the Copperhead features four side buttons, two on each side of the mouse. The buttons are fully programmable and can also be disabled. We found the new side buttons to be much more accessible than the ones on the Diamondback. Razer will offer a separate Pro-Tools upgrade kit that includes a customizable weight system and dummy buttons. The weight system will let you tune the weight of the mouse to fit your style. The dummy buttons can be installed to disable the extra side buttons."   continued ...   (Via GameSpot)
