Smartwatch Tactile Alerts for Identifying Notification Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartwatches that use vibrations for notification alerts do not allow the wearer to determine the nature of the notification message without consulting the watch dial, causing inconvenience and disruption.
Innovation Solution
A method and watch design that uses a tactile rendering interface with individually controllable vibrating elements to convey descriptive alerts through tactile sensations, allowing the wearer to identify notification content without sound, by processing notification data to select appropriate tactile signals based on predefined criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If audible signals are used for notification alerts, then the wearer can be alerted to the receipt of messages, but it causes annoyance when it disturbs the silence in places where it is essential
Solution Approach 1:
The patent replaces the acoustic alert system with a tactile alert system using a vibrating interface. The vibrating interface generates mechanical vibrations that can be felt by the wearer through the watch body, substituting the auditory notification mechanism while maintaining the alert function without causing auditory disturbance in silent environments
Solution Approach 2:
The patent changes the notification parameter from acoustic intensity to vibration characteristics. By varying vibration frequency, amplitude, and pattern, the system conveys different notification information through tactile sensations, allowing effective communication without auditory output
2Object-affected harmful factors
If vibrations are used as notification alerts, then auditory disturbance is avoided, but the wearer cannot determine the nature of the notification message based solely on the vibrations
Solution Approach 1:
The patent segments the vibration interface into multiple independently controllable vibrating elements arranged in specific patterns. Each element can be activated separately or in combination, creating distinct vibration patterns that encode different notification types, priorities, and content information, allowing the wearer to distinguish between different messages through tactile feedback alone
Solution Approach 2:
The patent applies different vibration characteristics to different locations on the watch body. Specific vibrating elements are activated based on the notification type, creating localized vibration patterns that convey information about the message nature. The spatial distribution and intensity of vibrations at different locations provide additional information dimensions for the wearer to interpret notification content
