User-Centered Design of an Attitude Aware Controller for Ground Reconnaissance Robots

Amber Michelle Walker, David P. Miller, Chen Ling
2015 Journal of Human-Robot Interaction  
Twenty-five users were recruited to assess usability of these attitude-aware controls, testing their suitability for both driving and camera manipulation tasks.  ...  The subtleties of these tasks require significant operator involvement-usually carried out locally to the robot's deployment.  ...  Controller B consisted of a driving-only attitude-aware control interface presented in landscape mode with full-screen video feedback.  ...

Speed-dependent automatic zooming for browsing large documents

Takeo Igarashi, Ken Hinckley
2000 Proceedings of the 13th annual ACM symposium on User interface software and technology - UIST '00  
By incorporating semantic zooming techniques, the user can smoothly access a global overview of the document during rate-based scrolling.  ...  An informal usability study suggests that for a document browsing task, most subjects prefer automatic zooming and the technique exhibits approximately equal performance time to scroll bars , suggesting  ...  USABILITY STUDY We performed a preliminary usability study to clarify the strengths and limitations of automatic zooming for the Web Browser and Map Navigation tasks.  ...

A Text Selection Technique Using Word Snapping

Motoki Miura, Kenji Saisho
2014 Procedia Computer Science  
Most of the text-selection task is performed at the boundary of words, however, the minimum movement unit of the region handle is still a character.  ...  Conventional copy-and-paste technique for touch screen devices utilizes region handles to specify text snippet.  ...  The virtual stick that emulates the function of joystick on a touch screen was implemented, and the performance was revealed.  ...

An attempt to define fully-accessible workstation levels of accessibility [chapter]

R. J. Cooper, Jeffrey C. Senge
1994 Lecture Notes in Computer Science  
The development and adoption of defined and standardized 'fully accessible workstations', which serve the needs of a great percentage of persons that require non-traditional access to computers, is a goal  ...  Although the needs of every person with a disability are unique to that individual, it is possible to develop standards based upon relative incidence and probable need of technology assistance.  ...  For those persons that can operate a pointing device but cannot access a normal keyboard or an oversize keyboard: 1) An On-Screen Keyboard program allows a person that can use a joystick, mouse, or a trackball  ...
