Apple Accessibility Features for Limb & Vocal Differences

Apple Enhances Accessibility Features Across Devices

At WWDC 2021, Apple unveiled a comprehensive suite of accessibility features designed to cater to diverse user needs. These advancements specifically address challenges faced by individuals who may have difficulty interacting with devices through traditional touch or voice commands. New options are now available for iPhone and Apple Watch users through innovations like Assistive Touch and Sound Control.

Assistive Touch: One-Handed Operation

Assistive Touch was initially introduced previously, but recent details have emerged regarding its functionality. This feature empowers Apple Watch users to operate their devices using a single hand through a range of gestures.

The development of Assistive Touch stemmed from feedback received from individuals with limb differences. Users expressed a desire for a more convenient way to answer calls than relying on unconventional methods.

Apple’s research team developed a system to accurately detect gestures such as pinching the thumb to a finger or clenching a fist. This detection relies on analyzing the subtle movements of the watch itself, rather than physiological signals.

These gestures, including their doubled variations, can be customized to trigger various quick actions. One notable function is the activation of the “motion cursor,” a pointer that mirrors the user’s wrist movements.

For individuals with limited hand function, this capability offers a valuable means of performing essential tasks like messaging, calling, and health tracking without relying on voice control.

Sound Control: Utilizing Unique Sounds as Commands

Recognizing that voice control isn't accessible to everyone, Apple introduced “Sound Control.” This feature allows users who can produce distinct sounds to utilize them as voice commands.

Sound Control is accessed through Switch Control, not through standard audio or voice settings, and requires the addition of an audio switch.

Users can select from a variety of sounds, including click, cluck, e, eh, k, la, muh, oo, pop, and sh. A training process ensures accurate sound recognition, enabling users to assign these sounds to a wide range of actions, such as launching applications or posing frequently asked questions.

Expanded Switch Control Compatibility

Apple has broadened the compatibility of its switch control system. Game controllers, previously limited to gaming purposes, can now be utilized for general device operation.

The Xbox Adaptive Controller, a versatile hub with customizable buttons and switches, is specifically highlighted. This tool is widely used to enhance accessibility in console gaming, and users will appreciate its expanded functionality beyond gaming applications.

Walking Steadiness: Monitoring Mobility

iOS now includes a feature called Walking Steadiness, available to all iPhone users. This feature tracks the user’s walking stability throughout the day.

The collected data, informed by the Apple Heart and Movement study, provides insights into patterns of movement and potential risk factors for falls.

This information can be particularly valuable for individuals recovering from procedures like prosthesis fitting or foot surgery, or those managing conditions like vertigo. Understanding fluctuations in stability can help identify potential hazards and track progress over time.

While the integration of this data into clinical practice remains to be seen, it empowers users to self-monitor and gain a better understanding of their own mobility.

Additional Accessibility Enhancements

Apple continues to expand its accessibility offerings with features like new languages for voice control, improved headphone acoustic accommodation, and support for bidirectional hearing aids.

Furthermore, the company has incorporated support for cochlear implants and oxygen tubes into Memoji customization options. Apple aims to embrace diversity not only through functional features but also through personalization and enjoyment.
