Multimodal Interaction for Text Entry and Control in Mixed Reality
… methods in Mixed Reality (MR) environments for text entry control. The central hypothesis is that these multimodal approaches can provide an expressive and efficient solution for (1) text input; (2) text editing; and (3) command retrieval, complementing the limitations of traditional input …

Novel text entry and mobile interaction techniques for Arabic language users
… this research aims to improve mobile data entry though better form navigation and improved Arabic text entry. Four improvements were taken into consideration in sequence: (1) minimizing large forms to fit small mobile device screens and easing form navigation process, (2) optimizing Arabic …

MusiKeys: Exploring Auditory-Physical Feedback Replacement for Mid-Air Text-Entry
… but the problem of how to best perform precision text-entry in XR remains unsolved. Physical QWERTY keyboards are the current standard for these kind of tasks, but if they are recreated virtually, the feedback information from sense of touch is lost. We designed and ran study with 24 participants …

Text entry, analysis and correction help : assisting the disabled computer user with data entry
It was suggested several decades ago that computers would be the single biggest step forward in integrating people with physical disabilities into "normal" society. At that stage, much work was done in writing software and designing hardware that allowed computer operators with disabilities to use …

Eyes-Free Input on Mobile Devices
… and studies that aim to improve eyes-free data entry for blind mobile device users. Currently, mobile devices are generally accessible to blind people, but text entry is almost prohibitively slow. Studies show that blind people enter text on an iPhone at a rate of just 4 words per minute. I …

Ergonomic, adaptable keyboard for fast data entry on mobile computing devices
… limited by the lack of an effective method for text entry. The currently available input options (such as the 12-key phone pad and PDA touch screens) are a quarter to a third of the speed of the standard desktop QWERTY keyboards. Therefore, it is slow and frustrating for people to use these …

Probabilistic User Interface Design for Virtual and Augmented Reality Applications
… design. This question is investigated in the context of text entry in VR with a probabilistic characterisation performed on two fundamental design choices. Research Question 2 relates to the challenge of adapting AR applications to deployment contexts not knowable at design time. A study in which …

Effects of Chemical Protective Clothing on Task Performance using Wearable Input Devices
… Sixteen active-duty soldiers performed a text-entry task with a wearable mouse and touch pad, while bare handed, wearing 7-mil, 14-mil, and 25-mil chemical protective gloves, wearing a respirator alone, and wearing the respirator and each of three gloves. Upon completion of the experiment, …

Design and Development of a Chatbot as an Alternative Web-browser for those with Severe Motor Impairments
… system integrates an innovative circular text-entry interface that centralizes frequently used keys, reducing unnecessary eye movement. In a subsequent study with 12 participants, EyeChat demonstrated a 4.1-fold increase in text-entry speed (from 2.41 to 9.88 words per minute), a reduction …

Human control of robots over discrete noisy channels with high latency: toward efficient EEG-based brain-robot interfaces
… be followed by the robot, and one interface for text entry, where the user’s intent was a desired character to be spelled. The first interface enabled users to navigate a simulated aircraft flying at a fixed speed and altitude over smooth paths that corresponded to a sequence of path primitives. …

A Usability Study of Nomon: A Flexible Interface for Single-Switch Users
… with Nomon in a picture selection task, while entry rates varied more in a text-entry task. However, we found participants had to click more times per selection using Nomon, motivating future research into mitigating this increased click load. All but one participant preferred using Nomon; most …

SSVEP-based BCI performance in children
… while the prior study asked children to perform text entry in a noisy environment. The game, which we developed and used for the first time in our study, is ``Brain Storm"" --- it allows a single player to pretend to be a farmer protecting crops from malicious lightning clouds using the power of …
