WearSkill: personalized and interchangeable input with wearables for users with motor impairments

We introduce WearSkill, a web application that implements personalized and interchangeable input for wearable computing. We outline functional and quality requirements for WearSkill and present the engineering details of its implementation using web technology. We emphasize the interchangeability of input modalities with various wearables, e.g., touch input on a smart ring vs. mid-air gestures of the hand wearing a smartwatch vs. voice input detected by the microphone from a pair of smartglasses, towards personalized input for users with various motor abilities. Our findings, from a study involving twenty-one people with motor impairments, show that WearSkill can provide accurate recommendations for personalized input modalities that match 85.3% with users' own preferences.
