Personal Artificial Intelligence: Synthesis and Understanding


 One day we will pick-up our enhanced smartphone and start a relationship with a new kind of confidant, a Personal Artificial Intelligence, or PAI (pronounced “Pie”). As our familiarity with our PAI grows, and the PAI’s knowledge of us expands, we will gradually form a more intimate bond. A bond that some may easily think of as friendship. Though this concept may seem improbable, even absurd, many of the prerequisites required are already in hand. Like the World Wide Web and social networking tools of today, artificial intelligence will be a blend of existing technology capable of transforming our lives in new and meaningful ways.
The realization of an Artificial Intelligence (AI) has proved more complex, and taken far longer, than first imagined. Serious research of machines that think first began in the 1950s. Scientists felt that automations would one day be capable of doing anything that a human could do. Although research toward that goal continues, there are some who feel the reality is unachievable, even potentially dangerous. But the process can be likened to the slow exploration of Mars. The pressures exerted by scientific curiosity, to explore its secrets, are irresistible, and the dangers can be mitigated.
Contemporary researchers generally define AI as a branch of computer science that attempts to create software that emulates human behavior. These studies include the storage and indexing of knowledge, planning, natural language processing, and machine learning. But the various branches of AI research have become deep and divergent. There are as many avenues of exploration as there are definitions.  However, the desirable features of a Personal Artificial Intelligence are easier to envision.
The evolution of a PAI began in the 1990s, when handheld computers called Personal Digital Assistants, or PDAs, became common tools. The user interacted with the various programs it ran on a resistive touch screen display using a stylus. The most useful programs were calendars that recorded events and appointments, contact lists, eBooks, a notepad and a camera. Smartphones evolved directly from the integration of a PDA with a cellphone. Smartphones added a variety of useful features including email access, text messaging, a web browser and the Global Positioning System hardware used by map applications. But a Personal Artificial Intelligence will not be like a PDA, or even a smartphone. The evolution from a smartphone to a PAI will require giant leaps of technology.
To understand the next steps in the development of a PAI, let’s discuss a few attractive features. A properly trained PAI will be able to recognize your mood and interpret your situation. To do this it will use stereo audio and visual inputs, and perhaps even gas odor detectors. It will be capable of using these sensors in the same manner as a human. For instance, it will be able to read your facial expressions, body language, and identify stress in your voice. It will sense and understand sleeping patterns, and moods, well enough to know when you’d rather not be disturbed by its communication features. When it prevents communication it will be capable of explaining the specific reasons to those trying to reach you. Of course it will also understand emergency messages and will be able to convey their urgency. Sensors will monitor your physical health, warning you if your body’s internal functions need medical attention. It will be able to decide when emergency assistance is required and make the call when needed. If a loved one dies it will offer to send flowers, make travel arrangements, and extend comforting words. All without being asked. None of these features are difficult, or beyond the reach of current technology. Many already exist. With that in mind we must ask ourselves again, what is AI and what is required to make this PAI a reality? The answer is twofold, synthesis and understanding.
 To perceive human reality, an AI’s software will synthesize the input of its sensors, and database of knowledge, to build a physical worldview. This worldview will update from instant to instant, and will be similar in quality to that perceived by a person. Of course this view will include enhancements. These include data like acceleration, angular momentum, humidity, temperature, altitude and exact world coordinates. However, to make sense of the environment around it, the AI needs understanding.
Understanding, perhaps, is the most challenging aspect of creating an Artificial Intelligence. Information can be gathered, synthesized and stored; but the key to intelligence is in interpreting its meaning. This will enable the AI to react in useful, and significant, ways. Large strides have already been taken on the road of this technology. Voice command recognition has improved drastically in the last few years. Face and object recognition are also in common use.
The concepts outlined here suggest the following enhanced definitions. Artificial Intelligence is the ability of a computer to synthesize, understand, and react to a human’s worldview. A Personal Artificial Intelligence is a portable AI that has bonded to a single individual. Though challenging, the potential benefits of a PAI, that can fulfill these definitions, shine a bright light on the road to developing this technology.

Imagine starting your car and your PAI asks you if you would like to stop anywhere before it drives you to work. On the drive home your PAI tells you its remote sensors indicate you are low on milk. At the grocery store your PAI uploads your shopping list and orders your favorite coffee. While an intelligent shopping cart gathers your products, you discuss concert plans with your PAI. The possibilities are endless, exciting and very real.
