GESTURE ANALYSIS FOR THE MANIPULATION OF GRAPHIC OBJECTS

IF MUCH OF THE FUTURE INTERACTION BETWEEN HUMANS AND GRAPHICS-CAPABLE COMPUTERS WILL INVOLVE MANIPULATING GRAPHICOBJECTS, IT MAKES SENSE TO DEVELOP AN INPUT DEVICE THAT LETS USERS DO JUST THAT IN THE MOST DIRECT AND INTUITIVE WAY, WITH MINIMAL USER TRAINING. THE RECENT AVAILABILITY OFAN ECONOMIC MEANS OF SENSING HAND GESTURES IN REAL-TIME PROVIDES THE MOTIVATION FOR THE RESEARCH PROPOSED IN THIS PROJECT. THE RESEARCHERS INTEND TO EVALUATE THE EFFICACY OF ALTERNATIVE GESTURES IN MANIPULATING GRAPHIC OBJECTS. THIS KNOWLEDGE WILL PROVIDE INFORMATION NEEDED TO IDENTIFY THOSE CLASSES OF GESTURES MOST APPROPRIATE FOR OBJECT MANIPULATION IN A PARTICULAR ENVIRONMENT. THE USE OF CAREFULLY-CHOSEN GESTURES WILL MINIMIZE THE DIFFICULTIES USERS EXPERIENCE IN INTERACTING WITH GRAPHIC SYSTEMS, AND REDUCE THE AMOUNT OF INFORMATION THAT MUST BE REMEMBERED BY USERS IN ORDER TO PERFORM GRAPHIC OBJECT MANIPULATION. THE RESULTS OF THIS RESEARCH CAN BE APPLIED TO DEVELOP A GESTURE-BASED SYSTEM WHICH ENABLES COMPUTER USERS TO MANIPULATE GRAPHIC OBJECTS USING EASILY-LEARNED INTUITIVE GESTURES TO PERFORM SUCH TASKS AS ASSEMBLING A PUMP OR MOTOR, CONTROLLING VEHICLES OR EQUIPMENT, OR CHANGING THE DIMENSIONS OF A DRAWING WHILE USING AN INTEGRATED GRAPHIC/TEXT EDITOR.
