Abstract
A remotely controlled device receives a command from a remote control (RC) but does not execute the command. Instead, the remotely controlled device accesses an audio file pertaining to the command and announces what the command is, so that a vision-impaired person can hear the command caused by the key that was just pressed. If the person wishes the command to be executed, he presses the key again within a threshold period. In another embodiment, the RC receives a press of a key but does not send the associated command. Instead, the RC announces the command. If the user wishes to send the command to a remotely controlled device, he presses the key again.
Claims16
A system comprising:
- a display device (DD) configured to receive wireless commands from a remote control (RC);
- circuitry in the DD configured to:
- receive from the RC a first command;
- responsive to being in a training mode, play on at least one speaker of the DD an audible indication of the first command but not execute the first command;
- responsive to receiving the first command a second time from the RC within a threshold period, execute the first command;
- responsive to not receiving the first command a second time from the RC within the threshold period, not execute the first command;
- and
- responsive to receiving the first command a second time from the RC after elapse of the threshold period, play on at least one speaker of the DD another audible indication of the first command but not execute the first command, wherein the circuitry is configured for configuring the DD in the training mode responsive to selection of plural keys.
A system comprising:
- a remote control (RC) with plural keys selectable to cause the RC to send respective wireless commands from a wireless transceiver of the RC to a display device (DD);
- circuitry in the RC configured to:
- receive a selection of a first key;
- play on at least one speaker of the RC an audible indication of the first key but not transmit to the DD a command responsive to receiving the selection of the first key;
- responsive to receiving a selection of the first key a second time within a threshold period, transmit a command to the DD corresponding to the first key;
- responsive to not receiving a selection of the first key second time within the threshold period, not transmit to the DD a command corresponding to selection of the first key;
- responsive to receiving a selection of the first key a second time after elapse of the threshold period, play on at least one speaker of the RC an audible indication of the first key but not transmit to the DD a command corresponding to selection of the first key;
- receiving, within the threshold period, a selection of a second key different from the first key;
- responsive to receiving the selection of the second key, announcing an indication of the second key but not transmitting a command to the DD corresponding to selection of the second key;
- and
- responsive to receiving the selection of the second key, restarting the threshold period.
A method, comprising:
- receiving at a display device (DD) a wireless first command from a remote control (RC);
- playing on at least one speaker an audible indication of the first command without further user input;
- starting a threshold period responsive to receiving the first command but not executing the first command unless the first command is received a second time prior to elapse of the threshold period;
- receiving, within the threshold period, a second command different from the first command;
- responsive to receiving the second command, announcing the second command but not executing the first or second command;
- and
- responsive to receiving the second command, restarting the threshold period.
