In this inventory, we proposed a new remote control, which could be used in disregard of making a distinction of its head and tail as well as checking the button to be pressed.

A bidirectional remote control

Our bidirectional remote control equipped two IR transmitters in both of its ends. The buttons also be designed on the diagonal symmetry.

When using our device, the user only simply remembers the layout of buttons in the panel, there is no need to care about the head or tail of remote control. In addition, Even the label of the button become unnecessary, which would be a great benefit to the blind.

Our invention is implemented by equipping the remote control with two IR transmitters in both ends. The buttons in the remote control panel are diagonally symmetrical, or can be divided into serval regions with each diagonally symmetrical. When a user presses a button, its IR signal is sent out by one transmitter as well as its diagonally symmetrical button’s IR signal is also sent out by the other transmitter simultaneously.

With a remote control in such a design, the user doesn’t bother to check the head of the remote control or the button to be pressed. Instead, the user only needs to remember the button position. The remote control can work identically regardless of which direction heading to the controlled object.

Fig 1 and Fig 2 illustrate how our invention works:


Fig 1. A bidirectional remote control – example with diagonally symmetrical regions


The remote control in Fig 1 is divide 3 regions – the upper, the middle and the bottom. All these regions are diagonally symmetrical. IR A and IR B are two IR transmitters.

Here is an example scenario:

• With IR A heading to the controlled object, button ‘1’ is now the most upper left of the middle region.

When a user presses: IR signal of button ‘1’ is sent out by IR A IR signal of button ‘9’ (button ‘1’ ‘s diagonally symmetrical counterpart) is sent out by IR B

Since IR A is directed to the controlled object, so button ‘1’ would take effect.

• With IR B heading to the controlled object, button ‘9’ is now the most upper left in the middle region.

When a user p...
