A sidewalker mobility aid for use in assisting an individual in walking. The device is configured to be used with one hand, on one side of the body of the user, rather than out in front, like a traditional walker. The sidewalker has features that place it between a cane and a walker, in terms of benefits provided. The device provides more lateral resistance (stability) than a typical cane, but less than a traditional walker, while having collapsible features that allow the device to take up less space than a traditional walker.

Methods, systems, and products estimate distances to aid a visually impaired user of a mobile device. As the user carries the mobile device, a camera in the mobile device captures images of a walking cane. The images of the walking cane are analyzed to infer a distance between a tip of the walking cane and the mobile device. The distance may then be used by navigational tools to aid the visually impaired user.

A push-pull walking stick includes a stick body, a wheel holder and a wheel. The stick body includes a tip and the wheel holder detachably connected to the tip. The wheel holder includes a connecting part, a shaft and a resist structure. The connecting part includes a fixed hole for containing the tip. The shaft is capable of moving along the direction of the stick body. The resist structure is located between the connecting part and the shaft. When the stick body applies force by the tip to the ground, the shaft moves toward the stick body and the resist structure resists against the wheel to stop the wheel from rotating. When the tip is located behind the user and the stick body moves forward with the user's pace, the shaft moves away from the stick body and the wheel rolls along the ground.
