Interactive training method and system is provided for the selective presentation of audio and video training program information to learner-operators. The audio and video program information is transduced from recorded program media under the control of a program control unit. The program control unit includes a computer that is responsive to a control program record. The recorded audio and video program information and the control program define a lesson of a training program. Each lesson includes a plurality of lesson segments or units. The interactive training system includes a video transducing device for a first program record that includes video program information and accompanying audio information. The video transducing device is capable of single video frame display as a still frame. The system also includes an audio transducing device for a second program record that includes audio program information. The program control computer is also responsive to recorded program data to output computer generated text and/or graphic video display frames. Each learner-operator interfaces the system via a light pen entry device that provides video display frame position information. The program control computer provides a presentation of the lesson by selectively controlling a combination of addressable information segments from the first and second program records and the computer generated text and graphic recorded data in a predetermined display format as modified by multiple branching capabilities in response to learner-operator entry data information.

An interactive training/expert computer system includes a computer subsystem for executing computer programs. A keyboard is used for entering data into the system, and a CRT displays the results of executing a computer program in the computer subsystem. A preselected computer program is resident in the computer subsystem. A tutor module interrupts the flow of data from the keyboard, interpreting and manipulating the input data, selectively generating messages in response to the input data, and selectively allowing a subset of the input data to be processed by the preselected computer program. The interpreting, manipulating, generating and allowing functions are dynamically determined in accordance with predefined criteria dependent on the contextual circumstances in the running of the preselected computer program.

A student interactive teaching system allows the student to learn at a level of skill appropriate to the student's learning achievements and learning abilities. The student progresses at a rate selected by the student. Ample opportunity is provided for the student to support and reinforce the learning process through student commanded repetition and review. The lessons are personalized by the recording and storage of student commentary. Video masking of the visual presentation allows the student to challenge his/her understanding of the subject matter when visual cues are inhibited. So too, the inhibition of audible cues tests the students abilities to learn and repeat verbal skills, such as are required in the theatrical arts.

In a system and a method of testing a person in the performance of cardiopulmonary resuscitation and for evaluating training exercises therein, a training device simulating a patient includes sensors for detecting various resuscitation procedures performed thereon. Parameter signals from the sensors are fed to a computer including a series of counters, a timing means and various memories, for analyzing the parameter signals and assessing whether the corresponding operations have been correctly or incorrectly performed. The values processed by the computer are then displayed on a display providing a clear moving representation of the procedures performed on the training device, the representation taking place in real time on the basis of corresponding signals from the timing means, whereby, by viewing the display, the trainee operator can directly check and if appropriate correct the resuscitation procedures he is performing. The display can display the whole of the cardiopulmonary resuscitation operation including preparatory procedures.

A medical investigative system in which a person interacts with the system to interject information that is utilized by the system to establish non-restricted environmental modeling of the realities of surrogate conditions to be encountered with invasive or semi-invasive procedures. This is accomplished by video display of simulated internal conditions that appear life-like, as well as by display of monitor data including, for example, blood pressure, respiration, heart beat rate and the like.
