Wearable Haptic Reminder Device for Spaced Retrieval Memory Aid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current memory assistance strategies, both modern and ancient, are ineffective in real-world situations, particularly for immediate memory needs, as they require access to devices or writing, which can be rude or cumbersome, leading to information loss, especially in conversations and daily life, and worsen with age.
Innovation Solution
A wearable wrist-based device with a single button that initiates a schedule of haptic reminders using a processor and vibrating motor, implementing the spaced retrieval memory strategy by providing increasingly spaced-out tactile alerts to aid memory retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional memory assistance methods (phone apps, writing) are used, then information can be recorded, but they are inaccessible or rude to use during conversations and daily interactions
Solution Approach 1:
The device separates the memory assistance function from traditional smartphones and computers, creating a dedicated wearable device that can be accessed instantly during conversations without the complexity and social stigma of using a phone or writing pad
Solution Approach 2:
The wearable device acts as an intermediary between the user's memory needs and the information they want to retain, providing a socially acceptable medium that bridges the gap between wanting to remember and the inability to do so during conversations
2Reliability
If spaced retrieval strategy is implemented manually, then memory retention improves, but it requires consistent self-monitoring and timing that is difficult to maintain
Solution Approach 1:
The device automatically manages the spaced retrieval schedule without requiring user intervention for timing or scheduling, performing the self-monitoring and interval management functions that would be difficult to maintain manually
Solution Approach 2:
The device automatically adjusts the retrieval intervals according to the spaced retrieval algorithm, changing the time parameters between reminders based on performance without requiring the user to calculate or set these intervals manually
3Reliability
If immediate memory assistance is provided during conversations, then information retention improves, but it may be perceived as rude or embarrassing
Solution Approach 1:
The device is designed as a simple, unobtrusive wearable that can be used without drawing attention, making the act of remembering feel less formal and more natural, thereby reducing the social friction associated with using traditional memory aids
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reduces memory-related friction, enhancing memory confidence and retention, particularly for healthy aging seniors, thereby preventing cognitive decline and dementia, and reducing unnecessary healthcare utilization.
Implementation Method 1
at least one haptic output device... a vibrating motor

AI summary
A wearable device to assist with memory that includes a processor, a haptic output device, and a button. When a wearer of the device encounters a piece of information they want to remember but thinks they may forget (e.g. the name of someone they just met; a phone number; a coupon code; an address; a new word definition, etc.) they simply press the single button on the device. The single button press initiates a pre-set schedule of tactile reminders about that piece of information. The reminders are vibrational and/or haptic outputs triggered by the processor that come quickly at first, and then become more spaced out over time. The device beneficially assists users in implementing the empirically supported ‘spaced retrieval’ memory strategy—where spaced retrieval refers to a method of retrieving information at longer and longer intervals to aid memory retention for selected pieces of information.
