- A fist and then an upward open palm activated the holoPADD. A tap of the badge deactivated the holoPADD.
- A squeeze and pulling out gesture of the hand activated the tricorder. Reverse movements deactivated the tricorder.
- A single tap on the badge would activate the transporter. A holographic coordinate system would appear, upon which the user would type in their destination. Then, the user would tap the badge and they would be transported.
- A double tap on the badge would activate the home button, which would transport the user back to where they were going.
Starfleet Command replaced the 23rd century badges of the USS Discovery crew with the tricoms. They were trained in how to use the tricoms by Lieutenant Audrey Willa and others. The first gesture taught to them was for activating the holoPADD. While some adjusted to the new badges, others, like Lieutenant junior grade Linus, found the adjustment more difficult. He struggled with the single tap and double tap functions of the badge, finding himself not where he wanted to be. (DIS: "Die Trying", "Scavengers")
The name of this technology is from Property Master Mario Moreira in the aftershow TRR: "Scavengers". He explained in the show how the badge was made in the prop shop and how it works in the Star Trek universe. He worked on the hand gestures, which the actors, like their fictional counterparts, had to learn.
The various ranks on the tricoms were shown in the aftershow.
