The motorized shade, such as a roller shade, comprises a shade material extending from a top end to a bottom end, a hem bar assembly connected to the bottom end of the shade material, and a shade drive unit operably connected to the top end of the shade material. The hem bar assembly comprises a touch sensing module adapted to detect a user touching the hem bar assembly and transmit a control signal in response to the detected touch. The shade drive unit comprises a motor and a motor control module adapted to receive the control signal and control the motor to open or close the shade material. The control signal can be wirelessly transmitted from the touch sensing module to the motor control module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch hem bar control","description":"A motorized shade for covering a window, a door, or a wall opening is provided that can be actuated by touching its hem bar.
