Research On The Interactive Aging Design Of Intelligent TV Voice User Interface From The Perspective Of Audio-visual Convergence

In the context of smart elderly care,smart TV has become the core of future home entertainment life for elderly users due to its ultra-high-definition viewing experience,fully open platform loading,and multi-modal interactive experience.Multi-modal voice interaction is used as a kind of The emerging smart TV operation method has a simple and natural interaction process and low learning cost,which can better cater to the usage habits of the elderly and realize a new audio-visual experience.However,due to the complex interface of the current product and the lack of content presentation and interactive operation paradigm suitable for elderly users,the elderly users are still in a state of inefficient experience for smart TV voice interaction experience.Therefore,how to design a smart TV voice interaction interface that meets the cognitive characteristics and interactive usage habits of elderly users has become the current research focus.This article takes elderly users as the research object,and analyzes and practices the age-appropriate design of the smart TV voice user interface from the perspective of audio-visual integration.First,through literature reading and market research,the development status,information architecture,and design performance of the smart TV voice user interface are sorted out,and the aging problems in the design of the smart TV voice user interface are studied with actual cases,and the interactive experience is found.breaking point.Secondly,based on the theory of cognitive aging,conduct in-depth analysis from multiple perspectives such as audio-visual fusion perception,working memory decline,and language aging representations,and clarify the priority of aging content and functions in the design.Then,through the use of a combination of quantitative and qualitative user research methods,the elderly users’ interactive awareness and experience perception of smart TV VUI under different interactive scenarios are studied,based on Kano analysis to determine the needs and pain points,and build an adaptive interactive experience model.Thirdly,starting from the interactive experience level of the smart TV voice user interface,design analysis from multiple perspectives such as auditory perception,visual perception,language cognition,and working memory,and propose aging-adaptive design strategies to better conform to the cognitive law of elderly users As the goal,improve user experience.Finally,based on the researched design model and strategy,the smart TV VUI adaptive design practice and system usability test are carried out to evaluate the effectiveness of the design.
