Communications has always been a symmetrical experience. From the first phone call, both users had essentially the same experience. Regardless if it was the two cans on the end of a string, two telephones with 12 keys, or a new UC client with video and Web Conferencing, all of the end users got essentially the "same" experience. This has changed somewhat as devices became more sophisticated but the end result was essentially the same. Newer advanced telephones with display may show more information, but the general experience, especially once the communications is started, is the same. This is also true in video, where the experiences are also generally symmetrical. Whether its using Hollywood squares or some other interface, all of the users get essentially the same experience.
Postulating that, there are two dimensions of diversity in communications experiences, one is the number of distinct communications events, the second is the variety of experiences in the event. As the chart shows below, we are already moving to a variety of different events. For example, many of us use traditional phone experiences, but now include Skype, web conferencing like WebEx or Go-To-Meeting, as well as a UC offer. It is generally agreed that WebRTC will change this by creating a much larger number of communications hosts and new paradigms. With over 200 WebRTC start-ups, many focused not just on communications, but other applications, this is going to be an explosion.
But, there has been virtually no change in the "symmetry" within a communication experience. Other than the exception of moderator tools in some conferencing platforms, the experiences that all of the users see is the same. However, the same technologies that enable web-based communications can rapidly lead to asymmetrical user experiences where the experiences are different for some or all of the participants based on the goal of the overall application and experience. The Google Cube Slam game is an example of this. While we are both in the same app, we each see the "pong" game board from a different perspective.
This will drive incredible innovation as applications developers and even users can define their Point of View, or the application can define different experiences based on roles or other factors. For example, a teacher instructing a group of students would have a very different experience than a student. If we add in a larger lecture with Teaching Assistants, the lecturer might see one view, each TA a view of their group and each student yet another view. Another example is first responders in an emergency situation. In a major trauma case, doctors may need to have video to each other, while an EMT might only need audio input, but see the video of the doctor. 911 and others might similarly have different views and optimization. This same type of end user optimization can be applied to a wide variety of situations, from meetings, to sales and beyond. The "Mayday" button in the Kindle Fire is a current real-life example of Asymmetrical Communications. In this services/application, the user gets video of the agent and pushed help info, while the agent gets audio from the user and screen sharing of the device. Both the media and presentation is optimized for very different experiences for both participants.
The entire WebRTC Eco-system needs to begin to think about communications events as integrated to the process or function, and not a stand-alone cookie cutter implementation. As this becomes clear, the capability to optimize different user experiences within a single event will become a major differentiator of the next generation of communications solutions. Over the next few years, expect to be surprised as the innovation of the web changes the user experience, and expect your users to ask you why your experience is so outdated.
