"You have no idea what you're doing, do you? You're just having fun with your hands..."Any situation where characters communicate with gestures and motions, usually of the hands, as opposed to using voices. This is often done specifically to avoid speaking, either because somebody present is unable to hear or comprehend a given language, because background noise drowns out any attempt at speech, or because the characters are sneaking and cannot make noise. American Sign Language (and those Sign Languages that are not American) is perhaps the perfect example, allowing deaf individuals to communicate with one another through the use of sight rather than hearing. Hand Signals are prevalent in reality as well as fiction. Whenever you indicate something by pointing at it, you're using a Hand Signal. Armed forces use them all the time, for convenience or stealth. Here, try it yourself: when someone approaches you, hold your hand out to them, palm-out, for "Stop." You didn't actually say "Stop," but the other person saw your gesture and probably knew its meaning intuitively. The "Cut-Off" signal, made by either pointing two fingers at your throat and waving back and forth or by drawing an extended index finger across your jugular vein, is also an example of a gesture with a universally recognized (not to say slightly disturbing) meaning. This trope is frequently played for laughs, usually through Lampshade Hanging. Instances include a character misunderstanding a signal, thinking a character is gesturing meaninglessly when they are attempting to frantically make themselves understood, and the gratuitous use of hand signals when they aren't required. Miming the Cues is a subtrope where one character attempts to surreptitiously coach another using improvised hand signals. This trope is not Body Language, and does not include habitual gestures like poses and tics. Also has nothing to do with Talking with Signs, which is about writing on wooden signs. A sufficiently developed set of Hand Signals may evolve into Talking Through Technique or an actual Signed Language.

Unfortunately, Gwen has no idea how to operate the equipment, and as such left the connection open for Serris to hear the entire thing.

Actual voice and other sound alerts are restricted to the ship's computer.

Most stories about Neanderthals written at this time did, because anthropologists believed that while Neanderthals were intelligent, they lacked a hyoid bone in their throat, which is necessary for sufficient variations in sound to evolve a complex spoken language. So they have a few spoken words and many signals. As Science Marches On, they found at least one Neanderthal with a hyoid bone.

- In the Erebus Sequence, Anea, as The Speechless, develops a sign language to communicate with people she knows (which is less cumbersome than restricting herself to written communication as she had previously done).
Live Action TV
- Game Shows: Producers and directors often use these to communicate back and forth to the host, when they don't want a contestant to be tipped off of the answer or the outcome of a game. These often will change over time as contestants get wind of the signals. One application is Wheel of Fortune, when the director signals (subtly) to Pat Sajak that the contestant has landed on the $100,000 or $1 million wedges.
- Buffy the Vampire Slayer. The Initiative uses military sign language, but the Scooby gang doesn't, which makes it hard for Riley to patrol with them. In one episode, Riley pumps his fist up and down, which the other characters interpret as a gesture meaning to follow him. "Like a train. Choo choo!" Then they start asking what it means. Very loudly.
Riley: It means "Yell real loud, so the vampires who don't know we're coming will have a sporting chance."Xander: See, now he's all mad and sarcastic.
- Used from time to time as serious, occasionally played for laughs in Stargate SG-1. When Stargate Command was once infiltrated, Jack and Daniel, as well as some Red Shirts, assemble outside of the infirmary. Jack, being a military Colonel, fires off a brief set of hand signals. Daniel, being a civilian archaeologist, signals back by exaggeratedly mouthing the words 'there are people in there', complete with pointing, and pantomiming a walking person with his fingers. Exasperated, Jack signals with his fingers the number three, brandishing his weapon with the other hand, indicating they'd simply rush the room together. Parodied in the very meta episode "200", in an imaginary sequence where Jack is turned invisible. On a mission, the other members of SG-1 sit there waiting, at which point Invisi-Jack asks "Can't you see my hand signals?"

- In the Farscape episode "Through the Looking Glass," John Crichton and Aeryn Sun are subjected to a loud, piercing noise that makes it impossible for them to hear one another. Failing to yell loud enough to carry a conversation, they both resort to amusing pantomime for the next several minutes. In particular, Aeryn indicates the sword-wielding D'Argo by chopping with an imaginary sword, and Crichton somehow manages to refer to the diminutive, froglike, hoverchair-riding Rygel by miming a small object floating up and down with his hands.
- Star Trek: The Original Series episode "The Doomsday Machine". When Spock relieves Commodore Decker of duty and Decker refuses, Spock gives a hand signal to a nearby security guard, beckoning them over to reinforce his threat to arrest him if he refuses.
- In the Star Trek: The Next Generation episode "Loud as a Whisper", Data learns sign language from the Enterprise computer banks to communicate with a deaf mediator when the mediator's telepathic chorus is killed in an ambush. Worf is fascinated by the idea of sign language as "communication that is both silent and covert."
- The glorious scene the Doctor Who episode "Partners in Crime," where the Doctor and Donna are spying on the same enemy from the opposite windows of a room. They notice each other, and hold an entire conversation, starting with distinct mouthing and evolving into miming with especial emphasis, before noticing that the group they were supposed to be watching was watching them.

CJ tells him to give a signal if he needs a break from the conference, and suggests he tug on his ear to let them know he needs them to make up a "something's gone wrong back home that needs the President on the phone" excuse. Unfortunately, CJ forgets to tell anyone else about this, largely because the President himself didn't take it seriously at first. She's absent for much of the conference, and returns to find the President frantically tugging on his ear.

- Switched at Birth has several deaf ASL speakers among the main cast and did an entire episode in sign language.
- The hosts commonly use a variant form of a scuba-diving "OK" sign, fist on top of head.

The sign is normally used for a diver to signal the dive boat as it is more easily seen than a smaller hand gesture.
- Adam goofs with his hand signs during "Underwater Car". Watch closely after he grabs for the emergency air on his first trip down in the car; he first uses a thumbs-up to try and tell Jamie he's all right, which really means "I need to surface" in this context.

- Clenching fists together and pulling them apart slowly in a stretching motion = Slow down. "You have more time than material, stretch it out."
- Spinning open hands or fingers over and around one another in a rapid circular/chopping motion = "Hurry up, commercial break/end of show approaching rapidly"
- Hand held palm up, a raising gesture: Louder. Palm down, patting gesture: Softer.
- One hand held vertical and still, the other horizontal with fingers together in a "mouth" shape. "Mouth" hand moving away from vertical hand: You're too close to the mike. Towards it: You're too far away, get closer.

- Divers, who cannot speak under water, learn a series of hand signals so that they can communicate with one another while submerged - basic ones include thumbs up for "I am ascending", thumbs down for "I am descending", open hand with spread fingers rocking back and forth for "Something is wrong", and three versions of "OK" - the normal one, a circle of thumb and fingers for when you are wearing gloves, and both arms making a triangle around your head for when you're too far from others for them to clearly identify a one-handed OK. The "Cut Off" gesture mentioned in the page head is intended for one of the most serious situations a diver can encounter: "I am out of air".
- Workers around noisy heavy machinery such as earth-movers, cranes, railroad locomotives, and aircraft have their own vocabulary of hand signals to communicate between the operators and those on the ground as there must be clear ways to direct and/or stop large things from moving in a hurry to avoid running someone or something over. For example, the basic railroad brakeman signals are: Up-and-down, go forward. Circular motion, back it up. Side-to-side, stop. (They're as simple as possible so as to be usable with just a lantern in pitch-black conditions.)
