“…However, it will be crucial in future studies to investigate a range of different graphical objects (e.g. shapes, typography, smaller/larger objects, longer/shorter distances [9,18,20,36]) and how users find the experience of positioning objects in these different design scenarios. We feel given the positive findings from the research highlighted that the approaches would still provide an accessible experience in these different contexts, although this will be important to validate.…”

People with physical impairments can experience challenges when using traditional input devices such as a mouse and keyboard for creative visual design work. Speech interaction is an alternative input method that can facilitate a more inclusive approach for supporting creative work. However, there has been a lack of work to date investigating how to position and move creative assets (e.g. images) around a digital workspace via speech interaction techniques. We present three multimodal speech interaction approaches to support the positioning of graphical objects around a design canvas via speech commands: Speed-based Control, Location Guides, and Positional Guides. A user evaluation with non-disabled participants (N=30) found that the Location Guides approach was significantly more efficient, accurate, and usable for the positioning of images when compared with the other methods. A follow-up study with physically impaired users (N=6) demonstrated they were able to effectively position images around a design canvas using the Location Guides technique with participants also rating this approach as exhibiting a high level of usability.

The voice-based technology is a promising alternative input modality to the conventional computer input devices, such as keyboards and mice. For mobility-impaired people who cannot use the traditional computer input devices, a voice-based interactive solution is highly desirable. Although some grid-based cursor control systems that use speech recognition show potentials, they come with limitations in processing time and difficulties in real-time applications. Since they are not natural enough to use, it is very slow to drill down the grid, and the point cursor selection range is prone to errors, and people need a more efficient and natural choice. To address these limitations, this paper proposes two novel speech-based target selection techniques: grid-based region selection (hereinafter referred to as "Region Selection") and grid-based target search (hereinafter referred to as "Target Search"). Region Selection allows users to select targets directly using the selected area. Target Search permits users to move the cursor to a target in a specified direction. Experiments are designed and conducted to analyze the impacts of target size and target density on performance and processing time. The experimental results and comparison study with traditional solution show that both Region Selection and Target Search improve the participants' accuracy of target selection and reduce the processing time, especially for small targets.

One of the main problems faced by blind learners is a lack of drawing technologies that support images and diagram drawing without the help of a sighted support worker. Even though some technologies have been experimented with in the past, blind learners have not been keen on tactile drawing due to: the difficulty of the drawing task, the length of time taken to complete a simple task, and the inefficiency of the drawing experience. This paper presents a set of grammar tools that can be used by blind people to find spatial orientation, as well as knowledge and representation of the interactive drawing environment, to improve the understanding of a concept or a subject matter. The grammar can be adopted and personalised in education and learning when presenting technical diagrams. The grammar enables users to present graphics by mapping the cognitive visualisation of blind people into spatial information on a computer screen. This technique promotes an interactive and easy drawing environment to build objects, associations, and layout information by zooming, navigation, and grouping. It will lead to future possibilities such as 3D world modelling, printing, and multisensory integration of inputs and output methods.
