HOLD Please vs EchoVision

HOLD Please A stage manager's soundboard for the modern theatre. HOLD Please is a one-tap voice cue board built for stage managers, ASMs, tech directors, and rehearsal callers. Instead of shouting across a noisy house or hunting for a microphone, just tap a button — a clear, pre-recorded voice cue plays through the room. Each button toggles play/stop, lights up red while it's broadcasting, and falls back to green when it's done. Cues are grouped into six sections so you can find what you need fast: • Stage Cues — Hold Please, Continue, Places, Freeze, Take it back, Thank you • Timing — 5/10/15/30 minute calls and breaks, "to places," "to curtain" • Production — Action, Cut, Rollem, Stand clear, That's a wrap, In 3, 2, 1 • Movement & Lighting — stage left/right/up/down, find your light, hold for lighting, tech difficulties, the show will resume • Quiet & Wrap — quiet backstage, quiet in the house, return for notes, done for tonight • Calling the Show — Go, Standby, LX, SFX, Stage Left/Right, Be Quiet (forceful)

EchoVision is an interactive mixed reality art experience that simulates bat echolocation using custom-designed, handheld, bat-shaped masks based on the open-source HoloKit headset. As users initiate sounds, they experience echolocation—the remarkable navigation method bats employ in darkness—through visual representations of propagating echoes mapped onto the real-world 3D shape of the surrounding environment, scanned in real-time by the LiDAR sensor of a smartphone mounted on the masks. By providing a unique glimpse into how non-human creatures perceive their sensory world, EchoVision promotes an ecocentric design perspective, fostering interspecies understanding and appreciation.
