Senorita: a Chorded Keyboard for Sighted, Low Vision, and Blind
Senorita: A Chorded Keyboard for Sighted, Low Vision, and Blind Mobile Users Gulnar Rakhmetulla Ahmed Sabbir Arif Human-Computer Interaction Group Human-Computer Interaction Group University of California, Merced University of California, Merced Merced, CA, United States Merced, CA, United States [email protected] [email protected] Figure 1. With Senorita, the left four keys are tapped with the left thumb and the right four keys are tapped with the right thumb. Tapping a key enters the letter in the top label. Tapping two keys simultaneously (chording) enters the common letter between the keys in the bottom label. The chord keys are arranged on opposite sides. Novices can tap a key to see the chords available for that key. This figure illustrates a novice user typing the word “we”. She scans the keyboard from the left and finds ‘w’ on the ‘I’ key. She taps on it with her left thumb to see all chords for that key on the other side, from the edge: ‘C’, ‘F’, ‘W’, and ‘X’ (the same letters in the bottom label of the ‘I’ key). She taps on ‘W’ with her right thumb to form a chord to enter the letter. The next letter ‘e’ is one of the most frequent letters in English, thus has a dedicated key. She taps on it with her left thumb to complete the word.

Gesture Typing on Smartwatches Using a Segmented QWERTY Around the Bezel
SwipeRing: Gesture Typing on Smartwatches Using a Segmented QWERTY Around the Bezel Gulnar Rakhmetulla* Ahmed Sabbir Arif† Human-Computer Interaction Group Human-Computer Interaction Group University of California, Merced University of California, Merced Figure 1: SwipeRing arranges the standard QWERTY layout around the edge of a smartwatch in seven zones. To enter a word, the user connects the zones containing the target letters by drawing gestures on the screen, like gesture typing on a virtual QWERTY. A statistical decoder interprets the input and enters the most probable word. A suggestion bar appears to display other possible words. The user could stroke right or left on the suggestion bar to see additional suggestions. Tapping on a suggestion replaces the last entered word. One-letter and out-of-vocabulary words are entered by repeated strokes from/to the zones containing the target letters, in which case the keyboard first enters the two one-letter words in the English language (see the second last image from the left), then the other letters in the sequence in which they appear in the zones (like multi-tap). Users could also repeatedly tap (instead of stroke) on the zones to enter the letters. The keyboard highlights the zones when the finger enters them and traces all finger movements. This figure illustrates the process of entering the phrase “the world is a stage” on the SwipeRing keyboard (upper sequence) and on a smartphone keyboard (bottom sequence). We can clearly see the resemblance of the gestures.

Manual Text Entry Remains One of the Dominant Forms of Human- Computer Interaction

This is because textual communication is one of the main reasons for using computers. Mobile and pervasive computing have been popular research areas re- cently. Thus, these issues have a major part in the thesis at hand. Most of the text entry methods that are discussed are for mobile computers. One of the three main contributions of the work is an architecture for a middle- ware system intended to support personalized text entry in an environment permeated with mobile and non-mobile computers. The two other main contributions in this thesis are experimental work on text entry methods and models of user performance in text entry tasks. -
Designing a Better Touch Keyboard
Designing a Better Touch Keyboard JOEL BESADA ([email protected]) DD143X Degree Project in Computer Science, First Level KTH Royal Institute of Technology, School of Computer Science and Communication - Supervisor: Anders Askenfelt Examiner: Mårten Björkman iii Abstract The growing market of smartphone and tablet devices has made touch screens a big part of how people interact with technology today. The standard virtual keyboard used on these devices is based on the computer keyboard – a design that may not be very well suited for touch screens. This study sought to answer whether there are alterna- tive ways to design virtual touch keyboards. An alternative design may require training to use, but the user should be able to use it viably after a reasonable amount of prac- tice. Optimally, the user should also have the potential to reach a higher level of efficiency than what is possible on the standard touch keyboard design. Analysis was done by researching current and previous attempts at alternative keyboard designs, and by imple- menting an own prototype based on analysis made on the researched designs. The thesis concludes that there is an interest in solving issues encountered in this area, and that there is good potential in building viable virtual keyboards using alternative design paradigms. iv Referat Utformning av ett bättre pektangentbord Den växande marknaden för smarttelefoner och surfplattor har gjort pekskärmen till en stor del av hur folket interage- rar med dagens teknologi.

Predicting and Reducing the Impact of Errors in Character-Based Text Entry
PREDICTING AND REDUCING THE IMPACT OF ERRORS IN CHARACTER-BASED TEXT ENTRY AHMED SABBIR ARIF A DISSERTATION SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY GRADUATE PROGRAM IN COMPUTER SCIENCE AND ENGINEERING YORK UNIVERSITY TORONTO, ONTARIO APRIL 2014 © AHMED SABBIR ARIF, 2014 Abstract This dissertation focuses on the effect of errors in character-based text entry techniques. The effect of errors is targeted from theoretical, behavioral, and practical standpoints. This document starts with a review of the existing literature. It then presents results of a user study that investigated the effect of different error correction conditions on popular text entry performance metrics. Results showed that the way errors are handled has a significant effect on all frequently used error metrics. The outcomes also provided an understanding of how users notice and correct errors. Building on this, the dissertation then presents a new high-level and method-agnostic model for predicting the cost of error correction with a given text entry technique. Unlike the existing models, it accounts for both human and system factors and is general enough to be used with most character-based techniques. A user study verified the model through measuring the effects of a faulty keyboard on text entry performance. Subsequently, the work then explores the potential user adaptation to a gesture recognizer’s misrecognitions in two user studies. Results revealed that users gradually adapt to misrecognition errors by replacing the erroneous gestures with alternative ones, if available. Also, users adapt to a frequently misrecognized gesture faster if it occurs more frequently than the other error-prone gestures. -

Interface for IT Generation 1 Front Matter 1.1 Executive Summary Driving the vehicle has been the primary task of the driver since the automobile was invented over 100 years ago. Yet as technology increasingly invades the car, the driver is required to divert attention to managing secondary (non-driving) tasks created by these technologies. The goal of the Toyota project is to investigate the types of secondary tasks that might be available to the IT Generation in future vehicles, and to design an interface that will allow the driver to accomplish these secondary tasks safely. The design team, a collaboration between Stanford University and the Tokyo Metropolitan Institute of Technology (TMIT), has explored many ideas for future vehicle functions and determined that most involve the idea of “connectedness.” The teams are focusing on improving this in-car “connectedness” by designing an interface system that allows drivers to create text while driving safely. Fig. 1: The Optimum Human Machine Interface for text entry while driving. The system consists of four components: a text input device, a logic core (software), an output device, and a test vehicle for collecting user data.
