had an experience of making a presentation?How do you feel about it?,What is the common structure of a presentation?And which parts are important and must be explained clearly?,What should you pay attention to when you give a presentation?,Is there anything else that you think is also important but has not been mentioned in the textbook for a presentation?,2,When We Need to Make a Presentation,Usually we need to present our research in a regular seminar or at a conference,.,3,What,Is,The,Clear Structure of,A,Presentation,Title of the presentation/name/affiliation of the author,Outline,Why/What you want to do,Prior art/related work/,whats new,How to do,Results,Evaluation:contributions/advantages/limitations,Applications/recommendations,Conclusion/future work,4,Sample:,Social Avatar Language for Natural Avatar-Based Human Communication,Dr.Jin Hou,Southwest Jiaotong University,5,Outline,What and Why we want to do,Related work and challenges,Our approach,Result,Conclusion and future work,6,Social Avatar Language(SAL),Avatar?,Graphical representation of a real person in a virtual environment,SAL?,Avatars,nonverbal,language in terms of,social context,Why SAL?,Our behaviors are influenced by social factors such as culture,profession,religion,Purpose!,Natural,sociable,personalized avatars7,Challenges,Where is the avatar from?,What is the personality of the avatar?,Body movement is mostly neglected and not synchronized with the face,Commercial products are available but usually rely on the pre-authored audio,8,What Has Been Done with Avatars,MIT Media Lab,Justine Cassell group,BEAT(Behavior Expression Animation Toolkit),Pennsylvania Univ.,Norman I.Badler group,EMOTE(Expressive MOTion Engine),Other:USC,NYU,F2F,Sony,9,BEAT,Advantages:,Currently the most satisfying animation toolkit that automatically extracts actual linguistic and contextual information from,text,to suggest appropriate hand and arm gestures,facial expressions,and intonation of voice,Allows animators to insert their preferred personalities,motion characteristics,or other particular features in the final animation,Disadvantages:,The imperfect computational linguistics is the greatest limitation in BEATs current version,Only performs for English input,10,EMOTE,Advantages:,Offers a methodological tool for creating personalized agents,which provides a method of synthesizing movements by controlling a relatively small number of,parameters,and enables a higher level of understanding communicative gestures,Acquire gestures with emphasis on arm and body postures that are largely neglected by other systems,Disadvantages:,Not provide an effective and easy-to-use tool for addressing the social context for avatars,Not consider multilingual input,11,Whats New in Our Study,New conception:SAL to reflect the social background of an avatar,Emphasis on cultural factor:Japanese,Chinese,American,Including body movement,facial expressions with appropriate eyes,eyebrows,and mouth movements,12,Our Approach-Ontology+VRML,VRML-based H-Anim Humanoid,Ontology Model,A,vatar,M,odeling,O,ntology(,AMO,):,puts the anatomic constraints on avatar animation,S,ocial,C,ontext,O,ntology(,SCO,):,associates the social context with avatars,13,Avatar Modeling Ontology(AMO),Define meta-elements(segment,joint),and further elements like body parts(arm,leg)and facial expressions(happiness,fear,disgust),Identity:distinguishes an entity from the others in terms of geometry,appearance,texture,color and so on,Dependency:describes all of the relationships an entity has,e.g.the upper arm adjoins the forearm,14,Social Context Ontology,(SCO),Associate the social context with an ordinary avatar-culture ontology,profession ontology,family ontology,religion ontology,Definition:a set of ontology elements,i,|i=1,n,where,i,=,Relationship,Generalization-,generalization,(Asian,Japanese),Disjoint-,disjoint,(teacher,student),Extension Mechanism:change/adapt the existing ontology or introduce a new ontology,15,Client-Server Topology,Query SCO,Retrieval,Database,Server,Client,Common Gateway Interface(CGI),Mapping Manager,HTML File,VRML File,Semantic Feature Extraction,SCO Profile,User Interface,VRML Browser,Character DB,Transform DB,Animation DB,SC,O DB,Keyword DB,16,Flow Chart of Animation Synthesis,17,私()正座()(I am sitting on my heels),18,我去游泳(,I go swimming),19,I Go Swimming,20,Facial Animation,21,Application,（,1,）,Graphical chat,22,Graphical Chat,Display concepts that would be very difficult to explain verbally to people from different cultures,such as“seiza”in Japan,or Tai Chi in China,A tool for enhancing international understanding across cultural barriers,by using both verbal and nonverbal channels,Current spoken language machine translations are not satisfying,our SAL can supplement machine translation and improve understanding through providing a visual aid,23,Application,（,2,）,Virtual interpreter,24,Virtual Interpreter,Increase believability and reality by both verbal and nonverbal behavior involved,especially with emotional expressions,Application to many fields like weather reporter,business or other service assistant,pedagogical agent,25,Conclusion,We originally propose to use ontology for addressing the social context for avatars,Integrates facial expressions with body gestures,Effective multi-natural language processing algorithm,This system is independent of the environment of the client so that it is widely applicable,A new interesting and valuable methodological tool for creating natural,sociable,and personalized avatars,26,Future Direction,More social aspects(ontology models):profession,religion,gender,interest,Expanding the input into other natural languages,Improve the natural language processing algorithm,27,Pay Attention,Speaking is not like writing!,Use simple and,clear,words,Never use ambiguous words and complex sentences,Focus on,the key points,Always l,et the audience know what you said and what you are going to say,Above all,what you really need is just:,A little,passion,+A lot of practice!,28,Practical Tricks,Avoid garish slides,Be sure that the words in slides are big enough and readable,The background and color are comfortable for audience,Three layers on one slide at most,Use understandable graphics,images and tables,Show some attractive and interesting demos in your research,Do not use animations too often,Move on naturally,29,Practical Tricks,Overcoming language barrier,Know your limitation:you are not a native English speaker,Practice more but perfect English is not necessary,and fluent English is enough for research communication,Remember that even native speakers have accent and create grammar mistakes,If you are not good at humor in English,then smile more!,30,Practical Tricks,Manner,Show respect to your audience,Keep yourself tidy and your clothes appropriate,Dont move your body or shake your head too often,31,Practical Tricks,Interaction,Propose questions and let the audience discuss,Anticipate the audience answers,Explain your thought about the questions,Avoid reading all the words from the slides and keeping your audience silent,Last but not the least:,be yourself always!,32,
