EyeSayCorrect: Eye Gaze and Voice Based Hands-free Text Correction for Mobile Devices

Text correction on mobile devices usually requires precise and repetitive manual control. In this paper, we present EyeSayCorrect, an eye gaze and voice based hands-free text correction method for mobile devices. To correct text with EyeSayCorrect, the user first utilizes the gaze point on the screen to select a word,…

Select or Suggest? Reinforcement Learning-based Method for High-Accuracy Target Selection on Touchscreens

Suggesting multiple target candidates based on touch input is a possible option for high-accuracy target selection on small touchscreen devices. But it can become overwhelming if suggestions are triggered too often. To address this, we propose SATS, a Suggestion-based Accurate Target Selection method, where target sel…

Voice and Touch Based Error-tolerant Multimodal Text Editing and Correction for Smartphones

Editing operations such as cut, copy, paste, and correcting errors in typed text is often tedious and challenging to perform on smartphones. In this paper, we present VT, a voice and touch-based multi-modal text editing and correction method for smartphones. To edit text with VT, the user glides over a text fragment w…

BackSwipe: Back-of-device Word-Gesture Interaction on Smartphones

Back-of-device interaction is a promising approach to interacting on smartphones. In this paper, we create a back-of-device command and text input technique called BackSwipe, which allows a user to hold a smartphone with one hand, and use the index finger of the same hand to draw a word-gesture anywhere at the back o…

Modeling Two Dimensional Touch Pointing

Modeling touch pointing is essential to touchscreen interface development and research, as pointing is one of the most basic and common touch actions users perform on touchscreen devices. Finger-Fitts Law [4] revised the conventional Fitts’ law into a 1D (one-dimensional) pointing model for finger touch by explicitly…

Write-it-Yourself with the Aid of Smartwatches: A Wizard-of-Oz Experiment with Blind People

Working with non-digital, standard printed materials has always been a challenge for blind people, especially writing. Blind people very often depend on others to fill out printed forms, write checks, sign receipts and documents. Extant assistive technologies for working with printed material have exclusively focused…

SteeringWheel: A Locality-Preserving Magnification Interface for Low Vision Web Browsing

Low-vision users struggle to browse the web with screen magnifiers. Firstly, magnifiers occlude significant portions of the webpage, thereby making it cumbersome to get the webpage overview and quickly locate the desired content. Further, magnification causes loss of spatial locality and visual cues that commonly defi…
