Automatically Correcting Typing Errors for People with Motor Impairments
نویسندگان
چکیده
People with motor impairments often have difficulty entering text accurately when typing on a keyboard. These users also may have trouble correcting errors. We introduce TrueKeys, a system that automatically corrects typing errors as they occur. TrueKeys utilizes a word frequency list and a model of the user’s keyboard layout to identify typing errors and choose appropriate corrections. We evaluated TrueKeys with 9 motor-impaired and 9 able-bodied users who completed phrase-typing trials with correction enabled and disabled. Results show that using TrueKeys significantly reduced the number of uncorrected errors for both motor-impaired (2.09% vs. 3.44% errors) and able-bodied users (1.03% vs. 1.83% errors).

Automatic Whiteout: Discovery and Correction of Typographical Errors in Mobile Text Input
We detect and correct typing errors made on mini–QWERTY keyboards by analyzing features of the typing itself. Examining a database of mini–QWERTY typing data reveals that many errors made by typists are “off–by–one” errors. One likely cause of these errors is the relative size difference between the user’s thumb and the small, densely packed keys of the mini–QWERTY keyboard. Our goal with this ...
متن کاملEvaluating accessibility through simulating the experiences of user users with vision or motor impairments
User studies involving users with disabilities often incur greater financial cost and complexity than those involving general populations. One consequence of this is that accessibility issues may not be identified during the earlier phases of design, when designs are still malleable. Additionally, it can be difficult to create controlled studies with multiple groups of very similar subjects due...

متن کاملEmbodied memory judgments: a case of motor fluency.
It is well known that perceptual and conceptual fluency can influence episodic memory judgments. Here, the authors asked whether fluency arising from the motor system also impacts recognition memory. Past research has shown that the perception of letters automatically activates motor programs of typing actions in skilled typists. In this study, expert typists made more false recognition errors ...
متن کاملA Listening Keyboard for Users with Motor
Computer users with motor impairments find it difficult and, in many cases, impossible to access PC functionality through the physical keyboard-and-mouse interface. Studies show that even able-bodied users experience similar difficulties when interacting with mobile devices; this is due to the reduced size/usability of the input interfaces. Advances in speech recognition have made it possible t...
