iOAK uses the camera to visualize the movement of the user and enables them to control switches. Key Functions: - Motion History This function colors the moved body parts with purple, blue, …, and red according to the frequency of the movement. - Air Switches Draw rectangles on the camera screen to serve as non-contact switches, called “Air Switches.” These can be activated by detecting movement within the designated areas. A red circle indicating the magnitude of the detected movement moves left or right along a slider on the screen. When it crosses the position of the sensitivity adjustment knob, a switch signal is output. For switch output integration, the user can select an external switch connected via Bluetooth (such as a "Relay" or the battery-shaped switch "MaBeee"), or the built-in “Home” or “Shortcuts” apps on the iPhone/iPad. - The “Relay” device works with equipment that accepts switch input. - The “MaBeee” device controls battery-operated equipment. - The “Home” app allows control of smart home devices, i.e., smart lights, plugs, and remotes, compatible with "Matter" or "HomeKit". - The “Shortcuts” app allows execution of a series of predefined actions (Shortcuts) on the iPhone or iPad. (*) (*) When linking with the “Shortcuts” app, add the “Open iOAK” action at the end of the registered “Shortcut” (the sequence of actions) so that it automatically returns to “iOAK” operation after executing the Shortcut. Compatible relay products are as follows: - DSD TECH SH-BT01A Bluetooth Module - DSD TECH 2-Channel Bluetooth 4.0 BLE Relay Module - DSD TECH SH-BT04B Bluetooth Module - TinySine TOSR141 - 4 Channel Bluetooth Relay - Switch Science ISP1507 Bluetooth-Relay Board
