A human computer interactions framework for biometric user identification

Computer assisted functionalities and services have saturated our world becoming such an integral part of our daily activities that we hardly notice them. In this study we are focusing on enhancements in Human-Computer Interaction (HCI) that can be achieved by natural user recognition embedded in the employed interaction models. Natural identification among humans is mostly based on biometric characteristics representing what-we-are (face, body outlook, voice, etc.) and how-we-behave (gait, gestures, posture, etc.) Following this observation, we investigate different approaches and methods for adapting existing biometric identification methods and technologies to the needs of evolving natural human computer interfaces

The History of the iPad

The purpose of this paper is to review the history of the iPad and its influence over contemporary computing. Although the iPad is relatively new, the tablet computer is having a long and lasting affect on how we communicate. With this essay, I attempt to review the technologies that emerged and converged to create the tablet computer. Of course, Apple and its iPad are at the center of this new computing movement

日本人大学生を対象にした英語学習ウエブアプリケーションの導入

This case study examines the introduction of web-based apps to Japanese university students for skill-based English learning. The focus is on 32 students from the International Studies and Education departments at a private Japanese university. The course was an elective English course titled,“ Current Events English.” In class, activities consisted of analog speaking activities from the textbook. However, web-based applications were introduced to support class preparation, the midterm, and the final project. The Memrise app for vocab learning was optional for class preparation. Use of Google Classroom was required for accessing the initial class documents, and Cambridge Write & Improve was required or the final project. Data was collected from the applications as well as from student surveys. The findings provide insight into the efficacy of webbased applications for language learning in Japan. It also contributes to the body of knowledge regarding the reticence of Japanese university students to adopt digital modes of language learning.本事例研究では日本人大学生を対象にした英語学習のためのウエブアプリケーション（WA） の適用可能性を明らかにする。対象は国際教育学科と教育経営学科の学生32人である。時事英語（選択教科コース）では主に教科書からのアナログ・スピーキング・アクティビティーを行ったが，授業の事前準備，中間発表，およびファイナルプロジェクトために三つのWAを導入した。学生主体の 事前準備のためにMemriseの語彙学習アプリを使用し，授業のシラバスおよびプリントを手に入れるためにグーグル・クラスルームを必要とした。ファイナルプロジェクトのためにCambridge Write & Improveも必要とした。WAと学生アンケートからデータを収集して分析した。本研究の結果は，日本人学生が言語学習にWAを使用することに控えめであるにもかかわらず，WAが語学学習には有効であるという知識体系を得られた

Optimizing Human Performance in Mobile Text Entry

Although text entry on mobile phones is abundant, research strives to achieve desktop typing performance "on the go". But how can researchers evaluate new and existing mobile text entry techniques? How can they ensure that evaluations are conducted in a consistent manner that facilitates comparison? What forms of input are possible on a mobile device? Do the audio and haptic feedback options with most touchscreen keyboards affect performance? What influences users' preference for one feedback or another? Can rearranging the characters and keys of a keyboard improve performance? This dissertation answers these questions and more. The developed TEMA software allows researchers to evaluate mobile text entry methods in an easy, detailed, and consistent manner. Many in academia and industry have adopted it. TEMA was used to evaluate a typical QWERTY keyboard with multiple options for audio and haptic feedback. Though feedback did not have a significant effect on performance, a survey revealed that users' choice of feedback is influenced by social and technical factors. Another study using TEMA showed that novice users entered text faster using a tapping technique than with a gesture or handwriting technique. This motivated rearranging the keys and characters to create a new keyboard, MIME, that would provide better performance for expert users. Data on character frequency and key selection times were gathered and used to design MIME. A longitudinal user study using TEMA revealed an entry speed of 17 wpm and a total error rate of 1.7% for MIME, compared to 23 wpm and 5.2% for QWERTY. Although MIME's entry speed did not surpass QWERTY's during the study, it is projected to do so after twelve hours of practice. MIME's error rate was consistently low and significantly lower than QWERTY's. In addition, participants found MIME more comfortable to use, with some reporting hand soreness after using QWERTY for extended periods

Interaction techniques for older adults using touchscreen devices : a literature review

International audienceSeveral studies investigated different interaction techniques and input devices for older adults using touchscreen. This literature review analyses the population involved, the kind of tasks that were executed, the apparatus, the input techniques, the provided feedback, the collected data and author's findings and their recommendations. As conclusion, this review shows that age-related changes, previous experience with technologies, characteristics of handheld devices and use situations need to be studied
