Process Overview

Empathize

Research Design

We conducted our research using a combination of quantitative and qualitative analysis. Specifically, we employed surveys and user interviews to gather data that was missing from the literature review, as well as to uncover more detailed and in-depth insights into user pain points and design opportunities.

Qualitative & Quantitative Data Analysis

For qualitative research, we used an affinity diagram to better organize and categorize complex responses. For quantitative research, we utilized charts to more effectively display the distribution of different answers.

Problem Statement

Elderly individuals frequently suffer from nocturnal leg cramps which lead to sleep disruption and seriously affect quality of life. NCLs are sudden, intense muscle spasms, and often affecting the calf muscle, below and behind the knee or in the soles of the feet. In severe cases, the pain and discomfort may linger for hours, leading to persistent soreness and daytime fatigue.

HMW

design a product that prevents and treats nocturnal leg cramps by promoting hydration, muscle relaxation and improved circulation while also providing instant pain relief and emotional support during cramp episodes, enabling users to manage their condition independently and improve their sleep quality?
