“…For example, Kane et al proposed more general guidelines for developing mobile services for people with visual and motor disabilities, such as support for highly flexible interface customization to arbitrary settings, and dynamic adaptation of user interface to increase accessibility in different outdoor environments [56]. More specific design approaches have been created to facilitate interactions for people with specific needs, such as sliding fingers on the screen instead of tapping for people suffering from tremors [57] or using pens and edges on the screen for people with motor issues [58]. Participants in our study also gave us some suggestions on how they usually address these problems when using their private mobile devices and proposed how the Connect Mobile app could be adapted to be more suitable to their needs.…”

BackgroundMobile phones and tablets currently represent a significant presence in people’s everyday lives. They enable access to different information and services independent of current place and time. Such widespread connectivity offers significant potential in different app areas including health care.ObjectiveOur goal was to evaluate the usability of the Connect Mobile app. The mobile app enables mobile access to the Connect system, an online system that supports cancer patients in managing health-related issues. Along with symptom management, the system promotes better patient-provider communication, collaboration, and shared decision making. The Connect Mobile app enables access to the Connect system over both mobile phones and tablets.MethodsThe study consisted of usability tests of a high fidelity prototype with 7 cancer patients where the objectives were to identify existing design and functionality issues and to provide patients with a real look-and-feel of the mobile system. In addition, we conducted semistructured interviews to obtain participants’ feedback about app usefulness, identify the need for new system features and design requirements, and measure the acceptance of the mobile app and its features within everyday health management.ResultsThe study revealed a total of 27 design issues (13 for mobile apps and 14 for tablet apps), which were mapped to source events (ie, errors, requests for help, participants' concurrent feedback, and moderator observation). We also applied usability heuristics to identify violations of usability principles. The majority of violations were related to enabling ease of input, screen readability, and glanceability (15 issues), as well as supporting an appropriate match between systems and the real world (7 issues) and consistent mapping of system functions and interactions (4 issues). Feedback from participants also showed the cancer patients’ requirements for support systems and how these needs are influenced by different context-related factors, such as type of access terminal (eg, desktop computer, tablet, mobile phone) and phases of illness. Based on the observed results, we proposed design and functionality recommendations that can be used for the development of mobile apps for cancer patients to support their health management process.ConclusionsUnderstanding and addressing users’ requirements is one of the main prerequisites for developing useful and effective technology-based health interventions. The results of this study outline different user requirements related to the design of the mobile patient support app for cancer patients. The results will be used in the iterative development of the Connect Mobile app and can also inform other developers and researchers in development, integration, and evaluation of mobile health apps and services that support cancer patients in managing their health-related issues.

“…When touchscreen input was compared with mouse input, Findlater et al [35] found that though touchscreen input was faster for people with motor impairments, it also led to a three-fold increase in pointing (tapping) errors on the touchscreen compared to the mouse. Some approaches to address these problems have used the edge of the screen to stabilize gestures [38,140], or a swiping ("swabbing") interaction rather than tapping, which allows the user to stabilize their finger on the screen itself [135]. For common touchscreen gestures like tapping, crossing and directional gesturing, Guerreiro et al [45] found that targets located at the bottom of the screen and next to the preferred hand were the easiest to select.…”

“…On the other hand, many studies have focused on making these mobile computing devices accessible. Some examples include utilizing the physical edges of the device [38,140] for better gesture stability, or touching and sliding the finger (called swabbing) [135] for target selection or analyzing touchscreen gestures to better understand the input preferences for people with motor impairments [35,45]. Particularly for wheelchair users and more closely related to my dissertation, Carrington et al [21] explored alternative input/output spaces on and around the wheelchair for accessible mobile computing and later, built a pressure-sensitive input technique on the armrest of the wheelchair to help people with motor impairments interact with mobile computing devices [22].…”

Emerging wearable technologies like head-mounted displays (e.g., Google Glass) and wrist-worn devices (e.g., Fitbit, Apple Watch 2.0) are always available, have the potential to provide quick access to information and offer relatively hands-free interaction compared to smartphones. Additionally, they can collect continuous health and fitness-related information of their wearer. For people with disabilities, these technologies may also offer possibilities of independent use. However, people with upper body motor impairments may not be able to gain from the potential benefits that these wearables can offer. For example, challenges related to performing multi-touch gestures and text entry, may magnify as the interaction space of some wearables gets even smaller. In my dissertation, I explore the potential impacts and assess the accessibility of existing mainstream wearable technologies, including head-mounted displays, smartwatches, and fitness trackers. Consequently, I implement and evaluate accessible wearable interactions for people with motor impairments for these wearables, specifically head-mounted displays and smartwatches.

“…In another invention, Montague et al introduced the Shared User Modeling Framework [25], an adaptive framework that aimed to improve touch accessibility across devices and applications. Wacharamanotham et al evaluated Swabbing [38], a technique for elderly adults to acquire targets by dragging their finger across a target rather than discretely tapping it. Unlike these techniques, which focused primarily on single finger touch input, Smart Touch improves touch accuracy while allowing users to interact with the screen in whichever way is most comfortable and natural for them.…”

We present two contributions for improving the accessibility of touch screens for people with motor impairments. First, we provide an exploration of the touch behaviors of 10 people with motor impairments, e.g., we describe how touching with the back or sides of the hand, with multiple fingers, or with the knuckles creates varied multi-point touches. Second, we introduce Smart Touch, a novel template-matching technique for touch input that maps any number of arbitrary contact-areas to a user's intended (,) target location. The result is that users with motor impairments can touch however their abilities allow, and Smart Touch will resolve their intended touch point. Smart Touch therefore allows users to touch targets in whichever ways are most comfortable and natural for them. In an experiment, we found that Smart Touch predicted the (,) coordinates of users' intended target locations over three times closer to actual intended targets than the native Landon and Lift-off techniques reported by the built-in touch sensors found in the Microsoft PixelSense interactive tabletop. This result is an important step toward improving touch accuracy for people with motor impairments and others for whom touch screen operation was previously difficult or impossible.
