Designing a Multi-Functional Walking Stick:
Synopsis:
An advanced walking stick that aids the Elderly who might not be as physically fit, have good memory, or eyesight. By understanding and empathizing with the issues they face on a daily basis, it seeks to exceed expectations to improve their quality and comfortability of life.
Additional Research:
NIOSH [National Institute of Occupational Safety and Health] stated that the max load weight to be lifted is 23 kg. However, for something that needs to be constantly / frequently lifted, and for someone who does not have the optimal physical strength, the design should be lighter.
Frequency: Every step taken, the walking stick has to be lifted
Target Audience: Elderly
Lifting Index according to the Recommended Weight Limit [RWL] will be below value 1.0 to impose low risk and decrease susceptibility to lower back injury.
Digital Interface:
The Home button will be located at the top of each page for consistency.

*A keyboard was replaced with audio input as it would be impractical to squeeze it into the small digital interface. It would also be an added hindrance and frustrate users who already have trouble with their sight.
Selecting any of the buttons would project out an audio as a form of feedback.
Physical Product:
Chair Design:
For increased stability, a 2-legged chair was installed. To adjust chair height, one presses the bases of the 2 legs. To-be designed with an S-shaped backrest, a natural seating position, this instills better posture for longer periods of time. For easy keeping, flip to close it.
Chair Material:
Plastic is lightweight for easier carrying.
Coupling Multiplier [1: (Good)] allows users to exert lesser gripping force when holding the walking stick. When lifting, it also ensures the vertical location of the user's hands. On top of that, comfortable wrapping around the Handle and Shaft section prevents excessive wrist deviations and awkward postures.
