I‘ve always thought text inputs from anything other than a keyboard were clunky. Cliff Kushler, the man who invented T9 (a word completion aid) has developed Swype, a new text entry method that capitalizes on eliminating the press and release component of the touchscreen. What was once a discrete target acquisition task becomes a continuous one.
In the CNET interview, Kushler points out his age (55) and his words-per-minute with Swype (50). Not bad.
If you’re interested in research on alternate text input devices, check out some of the following:
There was a report on electronic voting irregularities in South Carolina (during the Republican primaries last week) this morning on NPR. The person that was interviewed,a representative of the State Election Commission, naively stated that the machines were fine, but it was the users who were not following operating procedures. Here is a quote:
“Any voting system is dependent on its user following the proper operating procedures and, in this case, Horry County election officials missed a step,” he says. That step was closing out tests performed on the machines before the elections, which left some test votes still recorded and any affected machine locked up.
Unfortunately, this widespread view of blaming the user prevents designers and engineers from coming up with easier to use voting machines. If the problem lies with the user, the manufacturer/designer is off the hook in terms of fixing the problem.
From a user-centered design perspective (which has roots in human factors), you never blame the user! With the prevalence of voting system usability issues in the news, clearly, there are no usability or human factors people working within the manufacturers of electronic voting systems.
However, there is some hope. Human factors researchers Tiffany Jastrzembski and Neil Charness, at Florida State University, examined electronic voting machines to improve accuracy among older adults. The article, published in Ergonomics in Design, is a good example of applying the science of human factors to human-machine problems.
Improvements in simulator performance didn’t come from just any Wii (see image), or any game. Marble Mania is good, for example. Tennis (astonishingly fun to play on the Wii, which uses a motion-sensitive wireless control) isn’t so helpful. “The key is to have subtle hand movements,” Kanav Kahol one of the authors of the study, told the Health Blog. “You can’t hit a tennis swing and expect to become a better surgeon. You need fine motor control.”
More “function following form” with input devices…iDrive anyone?
With big knobs in cars that control the audio system being all the rage these days, designer Hao-Chun Huang wants to take the knob joke all the way to its logical conclusion and make a super, all-purpose metallic knob to control everything in your vehicle.
