The Raspberry Pi is controlled by a modified version of Debian Linux optimized for the ARM architec...Show More
This paper explores the efficacy of using an alternate text input system for the blind, based entirely on Braille alphabets for touch-screen mobile devices. A comparative study was performed wherein a prototype application developed by the authors was compared against the Voice-Over technology developed for iOS (Apple's mobile operating system. The study conducted on five blind subjects show that ...Show More
The authors collaborated with a power utility to evaluate input devices for use in the human system interface (HSI) for a new digital Turbine Control System (TCS) at a nuclear power plant (NPP) undergoing a TCS upgrade. A standalone dynamic software simulation of the new digital TCS and a mobile kiosk were developed to conduct an input device study to evaluate operator preference and input device ...Show More
Controlling a crane is often very difficult for human operators due to the slow response of the heavy structures and the lightly-damped payload oscillation. Manipulation tasks are made even harder when the interface between the human and crane is unintuitive. Although there have recently been significant advancements in portable electronic devices, this useful technology has not migrated into cran...Show More
Touch screen-enabled devices are proliferating in the communications and entertainment markets. In this scenario, the use of graphical passwords for user validation is receiving an increasing interest in the last years. Unlike in other fields of research on automatic user authentication, such as biometrics, there are no public databases of graphical passwords usable for research purposes (to the e...Show More
The autism spectrum is a neurodevelopmental disability covering a wide range of abilities and complexities [1]. The individuals experience varying levels of difficulties in communication, social, sensory regulation skills and engage in repetitive behaviours. Autism can also be accompanied by intellectual disability (ID) and or other comorbidities. Individuals on the autism spectrum often encounter...Show More
Continuing our previous work on developing comprehensive haptic feedback mechanisms for touchscreen based devices, this research elaborates how it is possible to incorporate the stick-slip phenomenon onto a mobile touchscreen to provide kinesthetic feedback for multimodal user interaction. Research has already proven that kinesthetic feedback is greatly beneficial in a wide range of activities, es...Show More
The paper aims to present the implementation of surface haptics feature on the optically bonded touch screen display, 10.4" of size, currently used on the AW169 helicopter; this technology has never been used in avionic environment up to now. A demonstrator has been realized and tested as an intermediate, verification, step to a prototype that will be mounted in the Agusta Westland AW169 helicopte...Show More
Project Touchport is a complete system that makes the human-computer interface convenient, simple and wireless. The system consists of two modules, the touchscreen module and the remote module. The touchscreen module can be used to convert any regular computer screen to a touch sensitive screen, eliminating the need for a new touch sensitive device. The remote module is a wearable device that can ...Show More
In line with our previous work, this research focuses on enhancing touchscreen based interaction through stick-slip phenomena. By balancing inertial and frictional forces on a transparent screen overlay, we can control the resulting directional forces specific to multiple objects on a touchscreen surface. Using “stick-slip” phenomenon, we can associate tangible objects in relation to their virtual...Show More
About decades ago, personal computers weren't portable and cell phones were rare luxuries. Today, take a quick glance at the 3C stores; many electronic mobile devices are portable. Actually, a legendary manufacturing company, Corning, has developed a special glass product, named Gorilla Glass, which designed the glass for electronic lifestyles or 3C products[2]. Such products are: tablets, smartph...Show More
Various information displays are becoming available for implementing new kinds of human computer interaction (HCI) methods. Touch screen devices become the most popular choice among many types and models. They have been used in wide range of applications and are proven to be a useful infrastructure for creating intuitive HCI. In spite of their popularity, there are some weak points. The most serio...Show More
This paper presents a spherical actuator-based hand-held device that provides lateral force feedback for user interaction with the touch screen. The spherical actuator is built around a ball containing the magnetorheological elastomer (MRE). This design of the actuator not only allows it to move in multiple degrees of freedom but also realizes its direct interaction with the touch screen and enhan...Show More
Various haptic displays are becoming available for implementing a new kind of human computer interaction (HCI) method. Among many types and models, touch panel displays have been used in wide variety of applications and are proven to be a useful interface infrastructure. In spite of their popularity, there are some weak points. The most serious drawback is their hardness to operate especially for ...Show More
Existing intrusive test automation techniques for touch screen applications (e.g., Appium and Sikuli) are difficult to work on many closed or uncommon systems, such as a GoPro. Being non-intrusive can largely extend the application scope of the test automation techniques. To this end, this paper presents RoScript, a truly non- intrusive test-script-driven robotic testing system for test automation...Show More
The traditional way of using pen and paper to take notes is getting over by the touch screen devices. These devices provide more options to the users to enhance their productivity while taking notes. The ability to recognize and validate the words written on the touch screens facilitates further capabilities to the users. Hence, in this paper, we describe a segmentation-based approach combined wit...Show More
To further expand the basic field of touch screen gesture research and understand the use of gesture combinations in college students' touch screen learning and its process. A survey was conducted on the preference of gesture combinations in touch screen learning among college students through online questionnaire collection. A total of 203 valid questionnaires were collected, and descriptive, dif...Show More
Currently, touch screen interfaces are adopted in many consumer products in our daily lives. However, there is still little empirical knowledge studied about their interaction, especially in food serving outlets. Therefore, in this paper we investigated how interact with using touch screen interface for self ordering some beverage and dessert. The method of this system consisted of three main part...Show More
In this paper we study keystroke dynamics as an authentication mechanism for touch screen based devices. The authentication process decides whether the identity of a given person is accepted or rejected. This can be easily implemented by using a two-class classifier which operates with the help of positive samples (belonging to the authentic person) and negative ones. However, collecting negative ...Show More
We present an eyes-free text entry technique for touchscreen mobile phones. Our method uses Graffiti strokes entered using a finger on a touchscreen. Although visual feedback is present, eyes-free entry is possible using auditory and tactile stimuli. In eyes-free mode, entry is guided by speech and non-speech sounds, and by vibrations. A study with 12 participants was conducted using an Apple iPho...Show More
As we are surrounded by an ever-larger variety of post-PC devices, the traditional methods for identifying and authenticating users have become cumbersome and time consuming. In this paper, we present a capacitive communication method through which a device can recognize who is interacting with it. This method exploits the capacitive touchscreens, which are now used in laptops, phones, and tablets...Show More
