  • A Multilingual Keyboard and Mouse Interface for Motor-Impaired Users
    SUITEDasher – A Multilingual Keyboard and Mouse Interface for Motor-Impaired Users David Lyle and Bill Manaris Computer Science Department, College of Charleston 66 George Street, Charleston, SC 29424, USA [email protected], [email protected] Abstract This paper presents the design of SUITEDasher – an open-source, multilingual speech user interface for motor- impaired users. SUITEDasher’s architecture is based on SUITEKeys – a speech user interface for manipulating a speech keyboard and mouse. SUITEDasher has three main design objectives: (a) to improve on the usability of its predecessor; (b) to provide for multilingual access; and (c) to be platform independent. To achieve these objectives, SUITEDasher employs a minimal graphical user interface, and incorporates a trigram-based probabilistic model from Dasher – a text-entry interface driven by pointing gestures. Multilingual access is achieved through a set of syntactic, lexical, and (potentially) phonetic models that may be loaded dynamically at run time. Finally, SUITEDasher is being implemented in Java as a cross-platform (Windows, Mac OS X, and Linux) application. While refining the design, we have developed several prototypes, the latest of which has been implemented in Visual Basic and C++ on the Windows platform. Preliminary usability results indicate that, in terms of typing speed, SUITEDasher appears to be 30% faster than its predecessor, and as fast as Dasher. Keywords: Universal access, motor impairments, speech user interfaces, listening keyboard, usability evaluation. 1 Introduction Several studies have been performed exploring the effectiveness of speech as an alternative to the physical keyboard for alphanumeric data entry. Murray et al. (1983) found that, in the context of controlling cursor movement, keyboard input is twice as fast and more preferred by users compared to speech.

  • Fast and Precise Touch-Based Text Entry for Head-Mounted Augmented Reality with Variable Occlusion
    1 Fast and Precise Touch-Based Text Entry for Head-Mounted Augmented Reality with Variable Occlusion JOHN J. DUDLEY, University of Cambridge, United Kingdom KEITH VERTANEN, Michigan Technological University, USA PER OLA KRISTENSSON, University of Cambridge, United Kingdom We present the VISAR keyboard: an augmented reality (AR) head-mounted display (HMD) system that supports text entry via a virtualised input surface. Users select keys on the virtual keyboard by imitating the process of single-hand typing on a physical touchscreen display. Our system uses a statistical decoder to infer users’ intended text and to provide error-tolerant predictions. There is also a high-precision fall-back mechanism to support users in indicating which keys should be unmodified by the auto-correction process. A unique advantage of leveraging the well-established touch input paradigm is that our system enables text entry with minimal visual clutter on the see-through display, thus preserving the user’s field-of-view. We iteratively designed and evaluated our system and show that the final iteration of the system supports a mean entry rate of 17.75 wpm with a mean character error rate less than 1%. This performance represents a 19.6% improvement relative to the state-of-the-art baseline investigated: a gaze-then-gesture text entry technique derived from the system keyboard on the Microsoft HoloLens. Finally, we validate that the system is effective in supporting text entry in a fully mobile usage scenario likely to be encountered in industrial applications of AR HMDs. CCS Concepts: • Human-centered computing → Text input; Additional Key Words and Phrases: augmented reality, text entry 1 INTRODUCTION Recent progress in head-mounted displays (HMDs) for augmented reality (AR), such as the Microsoft HoloLens, demonstrates the commercial potential of AR to support new forms of interaction and work in a range of industries including construction, education and health.

  • QB-Gest: Qwerty Bimanual Gestural Input for Eyes-Free Smartphone Text Input
    QB-Gest: Qwerty Bimanual Gestural Input for Eyes-Free Smartphone Text Input Linghui Ye1, Frode Eika Sandnes1,2(&) , and I. Scott MacKenzie3 1 Department of Computer Science, Oslo Metropolitan University, 0130 Oslo, Norway [email protected], [email protected] 2 Institute of Technology, Kristiania University College, 0153 Oslo, Norway 3 Department of Computer Science, York University, Toronto, ON M3J 1P3, Canada [email protected] Abstract. We developed QB-Gest, a bimanual text entry method based on simple gestures where users drag their thumbs in the direction of the desired letter while visualizing the Qwerty-layout. In an experiment with four sessions of testing, 20 users achieved text entry rates of 11.1 wpm eyes-free and 14.1 wpm eyes-on. An expert user achieved an eyes-free rate of 24.9 wpm after 10 rounds of entering the-quick-brown-fox phrase. The method holds potential for users with low vision and certain types of reduced motor function. Keywords: Mobile text entry Á Eyes free text Á Gestures Á Qwerty 1 Introduction Smartphones have become an important tool in modern society by facilitating com- munication independent of time and place. Many smartphone tasks require text input, such as searching the web, sending emails, or messaging. Text input typically uses a default virtual keyboard. Yet, many users find it hard to use virtual smartphone key- boards compared to physical desktop keyboards [1], because input requires accurately hitting keys without tactile feedback. Virtual smartphone keys are smaller than physical desktop keys; so, input is both visually intensive and requires careful eye-motor coordination [2].

  • 1 Background Many Applications for Handheld Electronic Devices Depend on the User Being Able to Enter Text
    ABSTRACT When using your smartphone (or similar handheld electronic device) with one hand, you have to type with the thumb, which isn’t the finger you would normally use. The more agile fingers are tied up with holding the device. This is due to the interface concept, not to any functional deficit of the human hand. You could operate these devices with the use of all fingers, and not just for typing, but that calls for a different interface paradigm, one that mirrors the ergonomic capabilities of the human hand. You engage this kind of interface where your fingers spontaneously come into contact with the device when you grasp it, not at predetermined locations that are not necessarily easy to reach. This interface dynamically maps the controls of the device to the contact patches of your fingers and generates a visual, audible or haptic tag to tell you what function a finger controls. To activate a control you engage it with the corresponding finger. KEYWORDS Topical† tactile interfaces, atopical* tactile interfaces, operative interaction with back and sides of device, accessibility issues with virtual controls, atypical handheld devices (disks, cylinders, torons etc.) †characterised by operative interactions confined to defined locations *characterised by operative interactions not confined to defined locations 1 Background Many applications for handheld electronic devices depend on the user being able to enter text. To this end, the tactile user interfaces of these devices are configured with a miniature keyboard. The idea behind this is presumably to replicate the functionality of a standard keyboard. This may be aiming a little too high, though.
