User Journey Map
Human reachable range decreases with age. The normal intersect of reachable range for adults is 990 mm. As age goes, there is an average of 70 mm range of reaching difference between people aged 40 and 80.
Human can lose 3% to 5% of their muscle mass per decade after age 30. An average of 8-12% less of strength requirement should be considered into products for seniors.
Handles are great mobility aids. A relatively large, comfortable handle should be considered when there needs a support.
The fingers start to lose sensitivity with age. A senior product should provide fingers with more sensation. A harder surface or interface can give seniors stronger feedback so they know whether they operate products correctly.

Senior mobility issues affect every aspect of senior's life, especially in safety concerns. Current product, such as walker, only focuses on solving one mobility problem at a time. Although it helps seniors walk, problems still remain when it comes to switching between sitting and standing. Walking, standing and sitting have yet to be addressed as whole, which has ignored by most designers.
