Abstract

Objective: This study aims to discover Priority of Hook type Wearable Device's PUI variabels and derive Hook related variables' specification by conducting objective measure. Background: With rapid increasing interest of Health-care Services and ICT technology, the research of Wearable Devices for Sport are becoming main concern. However, Most research of wearable devices are conducted in Economic aspects. And, Hook Type Wearable devices are stay in close to ears but there is not enough studies which are concerning ear characteristic. We need research of discover priority between Hook type wearable device's PUI variables and PUI Guideline which lower discomfort. Method: First, in 1st research, Research of market's Hook type Wearable Devices' PUI Specification. Next, Derive PUI variables and Prototypes with Orthogonal Design. And conduct a discomfort test with dynamic task. Second, in 2nd research, Derive Hook related PUI variables and Prototypes with Full Factorial Design. Conduct a discomfort test with dynamic task. Results: The PUI variables' priority is revealed as Padwidth, Outerwidth, Innerwidth, Upperlength, Lowerwidth, Lowerlength, Paddepth. And PUI variable's which are revealed lowest discomfort are 28mm width, 34mm Upperlength and 3 R value. Conclusion: This study evaluates the discomfort in Dynamic Task that affects the feel of Dynamic environment. Based on study results, a guideline for Hook type Wearable Devices is 28mm Width, 34mm Upperlength and 3 R value. Application: This study is expected to be used as basic data for designing Wearable Devices, as well as Hardware in the industries which are related to ear.
