The movement based visual signals have been neglected long time but increasingly got much research with the development of 3D digitalizing and animation techniques. Many interesting questions, such as how and why motion signals vary? Are there specific condition-dependent motion signals? What is the function of each motion component? The Asian agamid genus Phrynocephalus became excellent systems for those questions, because both males and female this group made complex tail displays during social interactions, such as male-male competition, male courtship and female-female competition, even proportion of offspring display their tails in face to adults and other offspring. As the basic research for more complex design, we filed the tail display signals under different signal contexts, including male-male, male-female, female-female, offspring-male, offspring-female and offspring-offspring using two cameras, and the signal structure from each context would be quantified with 3D digitalizing methods. To understand the efficacy of each component, one 3D animation was also tested in the field. We would modify the present 3D animation with the collected videos. More pilot tests on the 3D animation would be carried out late this year.
