Description: PHONE BASED DYNAMIC IMAGE ANNOTATION Background of the Invention Field of the Invention The present invention relates to the storage and retrieval of multimedia messages and more particularly to utilizing the store and forward capabilities of a voice mail system for multimedia messages containing dynamically annotated images. Description of the Prior Art The availability of hardware and software to generate, store and distribute digital media (text, voice, images, video, graphics, etc....) has enabled the development of multimedia messaging systems that give people the ability to communicate without having to be in the same place at the same time. In order for these systems to be effective, they must provide the means to convey as much information as possible in a simple and intuitive way. Within this context, the concept of image annotation which involves the ability to superimpose voice, text, graphics and mouse movements on a previously recorded image is appealing because it lets the sender act as if the receiver were present. For example, a person could verbally and graphically describe the way in which a document could be changed as if the other person was standing next to him/her. In general, dynamic image annotation extends the way in which people can use computers to communicate. The use of annotation to enhance computer-based communication has been available in various forms. In its simplest way, text documents can be extended with special markers that resemble "post-it" notes where a person could add typewritten comments. More sophisticated systems enable the creation of annotations on images or documents that include sound and graphics. However, in these it is assumed that the computers where the annotations are generated and played back possess the necessary hardware/software to perform audio recording and playback. It is an object of the present invention to develop a unigue annotation that can be used in environments where the computers used to compose and play back the annotation lack audio capabilities, but where a separate telephone device is available. The basic idea is to use the computer to record graphics and mouse movements (gestures) and a voice mail device to record the voice component of the message. Summary of the Invention The present invention extends the use of dynamic image annotation to PCs or workstations lacking full multimedia capabilities. The system enables the composition, storage and retrieval of multimedia messages containing dynamically annotated images by utilizing the store and forward capabilities of a voice mail system and a telephone device to carry the voice/sound portion of the message. The system includes protocols used to maintain the synchronization of the voice/sound components of the message during recording, storage and playback. Brief Description of the Drawings Figure 1 illustrates four potential multimedia scenarios. Figure 2 illustrates the record protocol of one embodiment of the present invention. Figure 3 illustrates the playback protocol of one embodiment of the present invention. Figure 4 illustrates system components of a test of the present invention. Detailed Description of the Invention Figure 1 illustrates four scenarios in which the dynamic annotation of the present invention can be used within a voice mail environment. In scenario 1 a user with a multimedia PC 11 accesses the voice mail system 15, including dynamic image annotation, through a local area network 12. In scenario 2 a user with a non-multimedia PC 13 (i.e., a PC without speakers, microphone or telephone interface) accesses the services of the voice mail system 15 through the telephone 14 and the local area network 12. The telephone connection is achieved by means of a public branch exchange (PBX) 16. In scenario 3 a user of a portable non-multimedia PC 17 (i.e., a portable PC without speakers, microphone or telephone interface) accesses the services of the voice mail system 15 through the public telephone network 20 by means of a telephone 18 and modem 19. In scenario 4 a user with a multimedia PC 21 accesses the services of the voice mail system 15 remotely via the telephone network 20. Of particular interest to the present invention are scenarios 2 and 3 which require the availability of a telephone device. More specifically, in scenario 2, the voice component or the annotated message is carried over the voice network while the graphics and gestures travel simultaneously over the local area network. In scenario 3, the voice component of the annotated message is again delivered to the voice mail system over the voice network. The rest of the annotation, including the image, graphic and mouse gestures, are also delivered to the voice mail system via a separate phone line. In an alternative implementation of scenario 3, the graphics and gesture components of the annotation can be recorded in the local PC and delivered to the voice mail system over the same telephone line that carried the voice. A typical multimedia annotated message consists of one or more images, a voice/sound message and a timed sequence of gestures consisting of drawings, mouse movements and viewing commands, all of which are synchronized in time. The objective of the present invention is to design a protocol that will enable the separation of the voice/sound component during transmission and storage and the reattachment of the voice/sound component during playback. The key problem in the development of this protocol is the identification of suitable synchronization mechanisms. Figure 2 illustrates the recording portion of a protocol and the interconnections between the computer 24, the local area network 26, the voice mail system 28, the PBX 30 and the telephone device 32 of one embodiment of the present invention. The user begins a session by selecting the recording mode, then chooses the image(s) to be annotated. When the selection is completed the system will ask the voice mail system 28 to initiate a call to the appropriate telephone device 32 and then will enter a waiting state. It is assumed that there are mechanisms in place to determine the device to be called and to validate the user identification. The voice mail system 28 will initiate the call, wait for the user to answer and play a prompt indicating the reason for the call and asking the user to perform a specific action, e.g., push a button to confirm that he is ready to begin annotating the image(s) . Upon receiving confirmation from the user, the voice mail system 28 will then instruct the annotation program on the PC 24 to go ahead with the annotation and will begin recording the voice message sent through the telephone device 32. Notice that there are real-time constraints to be satisfied in this step. More specifically, the system must be able to instantly notify the annotation program to go ahead. The program must also be able to return from the waiting state immediately. A series of synchronization marks (Ti) are recorded during this step to keep track of the duration of the session. In particular, Tj refers to the time elapsed between the point where the annotation /11549 PC17US96/13217 begins and the first pause, T 2 refers to the duration of the first pause and T 3 to the duration of the second segment of the annotation. Notice that markers T 4 , T 5 ,... may be needed if there are two or more pauses during the recording of the annotation. The user will indicate completion of the annotation by pressing a 'STOP' button and hanging up the telephone device 32. The session will be completed (from the user's point of view) when the user issues a 'SEND' command. The system will continue its communication with the voice mail system 28 in the background, sending the image(s) , gestures and synchronization markers to the message store where they will be stored with the voice portion of the message. Figure 3 illustrates the steps to be performed during playback. The interconnections between the computer 34, the local area network 36, the voice mail system 38, the PBX 40 and the telephone device 42 are as shown in Figure 2. In the first step, the user receives a list of the messages available and selects one to be played back. The next two steps in the process are similar to those described in the protocol above. In the third step, the user will receive the voice message over the telephone device 42 while the gesture portion of the annotation is being displayed on the screen of the computer 34. The synchronization markers collected during the recording session will be used to coordinate the two devices. More specifically, the gesture player will periodically compare the execution and real times. If necessary the gesture player may drop small gestures to speed up the process. The gesture player may also introduce small delays to re-synchronize the voice and gesture annotation. As a test of the present invention, a simple concept system was created that simulates the functionality of a telephone and voice mail components. This system is illustrated in Figure 4. The system consists of three UNIX processors running on two separate workstations. Processor 1 runs the image annotation software extended with remote procedure calls that simulate the communication that would take place with the voice mail server. Processor 2, running in the background, simulates the functionality of the voice mail system; it receives and sends commands to the annotation program (processor 1) and telephone device (processor 3) as defined in the protocols. Finally, processor 3 is used to emulate a standard telephone device. It uses a graphical user interface and the microphone and speakers of a second workstation to record and play the voice portion of the message. The above testing system shows that the desired functionality of the present invention is achievable. As stated above, the present invention extends the use of dynamic image annotation to PCs or workstations lacking full multimedia capabilities. Additional benefits derived from the use of a telephone to transmit the voice/sound component of a multimedia message include an improvement in the quality of the sound recorded and delivered and a reduction in traffic and bandwidth requirements of the local area network. It is not intended that the present invention be limited to the hardware or software arrangement, or operational procedures shown disclosed. This invention includes all of the alterations and variations thereto as encompassed within the scope of the claims as follows.
