Action: Appear in front of the camera or exit the frame to enable the game state. Application: Hide and seek, personal scene entry, interactive mirror. Technologies: Recognition or machine learning model. <a id=\"variant-cam-073\"></a>\n- Head position. Action: Move your head in the frame and control the character or cursor. Application: Contactless arkanoid, evasion, accessibility interface. Technologies: Recognition or machine learning model. <a id=\"variant-cam-074\"></a>\n- Turn to the sides. Action: Turn your head left and right to select direction. Application: Steering, response selection, view control. Technologies: Recognition or machine learning model. <a id=\"variant-cam-075\"></a>\n- Head tilt. Action: Tilt your head to your shoulder and change a continuous parameter. Application: Balance, flight, tilt of a virtual surface. Technologies: Recognition or machine learning model. <a id=\"variant-cam-076\"></a>\n- Nod or denial. Action: Perform a sequence of tilts or turns for a discrete command. Application: Dialogue, confirmation, rhythm game. Technologies: Recognition or machine learning model. <a id=\"variant-cam-077\"></a>\n- Approaching face. Action: Change the visible scale of the face relative to the calibration. Application: Inflating a virtual bubble, zoom, comic transformation. Technologies: Recognition or machine learning model. <a id=\"variant-cam-078\"></a>\n- Maintaining head posture. Action: Stay in the desired angle range for a given time. Application: Balancing game, beam holding, precise targeting. Technologies: Recognition or machine learning model. <a id=\"variant-cam-079\"></a>\n- Several faces. Action: Gather the required number of participants in the frame and evaluate their location. Application: Group portrait quest, cooperative gate, party game. Technologies: Recognition or machine learning model. <a id=\"variant-cam-080\"></a>"},{"id":"context","title":"Context and limits","body":"Games, learning, creativity and interactive applications.
