What are virtual assistants
Virtual assistants are computer programs that can communicate with users through natural language, whether written or spoken. They can understand the intentions, needs and preferences of users, and provide appropriate responses or actions. They can use different communication channels, such as text, voice, image, video to interact with users, depending on the context and the device. They can also integrate with other applications, platforms and systems, to access external data and services.
Virtual assistants are different from simple chatbots, which are programs that follow predefined rules to answer questions or commands from users. Virtual assistants use artificial intelligence techniques, such as natural language processing, machine learning and computer vision to learn from data and user feedback, and improve their performance and experience. They can also adapt to the profile, mood and context of users, and offer personalized responses or actions.
How virtual assistants work
Virtual assistants work through a four-step process: input, understanding, processing and output. Let’s see each one of them in detail.
Input
Input is the way the user communicates with the virtual assistant, whether by text, voice, image, video etc. The virtual assistant needs to capture and analyze the user’s input, and transform it into a format that can be understood by the system. For example, if the user speaks with the virtual assistant, the system needs to use speech recognition to convert the audio into text. If the user sends an image or a video, the system needs to use computer vision to extract the relevant features and objects.
Understanding
Understanding is the step in which the virtual assistant understands what the user wants, what is their intention, what is their need, what is their preference etc. The virtual assistant uses natural language processing techniques to analyze the text, image, video or other type of user input, and identify the entities, relations, emotions and feelings involved. The virtual assistant also uses machine learning techniques to learn from data and user feedback, and create models that can predict the best responses or actions for each situation.
Processing
Processing is the step in which the virtual assistant performs the appropriate response or action for the user, according to their understanding. The virtual assistant can use different methods to do this, such as searching for information in databases, accessing external services, controlling smart devices and generating content, for example. The virtual assistant can also use reasoning and planning techniques to solve problems, make decisions, optimize results and others.
Output
Output is the way the virtual assistant communicates with the user, whether by text, voice, image, video or other. The virtual assistant needs to generate and present the output to the user, in a way that is clear, friendly, relevant and satisfactory. The virtual assistant also needs to use a format that is suitable for the context and the device of the user. For example, if the user is driving, the virtual assistant can use a voice to talk to them, instead of a text. If the user is using a smartphone, the virtual assistant can use an image or a video to show something, instead of a long text.
Functionalities and services that virtual assistants offer
Virtual assistants can offer various functionalities and services for users, depending on their purpose, their domain, their target audience etc. Some examples of functionalities and services that virtual assistants can offer are:
- Search for information: virtual assistants can search for information on the internet, in databases, in documents etc. and provide the answers or the results for the users. For example, virtual assistants can answer questions about facts, events, people and places or show the news, the weather, the traffic…
- Schedule appointments: virtual assistants can schedule appointments for users, such as meetings, consultations, trips etc. They can check the availability, the time, the place and other data of the involved parties, and confirm or cancel the appointments as needed.
- Control smart devices: virtual assistants can control smart devices, such as lamps, thermostats, cameras etc. that are connected to the internet. They can perform actions such as turning on, off, adjusting or monitoring the devices, according to the commands or the preferences of the users.
- Shop: virtual assistants can shop for users, such as products, services and tickets. They can search, compare, recommend, book and pay for the available options, according to the criteria or the preferences of the users.
- Entertain: virtual assistants can entertain users, such as playing, telling stories, making jokes, playing music etc. They can interact with users in a fun, creative and exciting way and provide moments of leisure, relaxation and fun.
- Educate: virtual assistants can educate users, such as teaching, training, evaluating, guiding etc. They can offer content, activities and feedback that are suitable for the level, the pace and the style of learning of the users.
Challenges and opportunities for the development of virtual assistants
Virtual assistants face various challenges and opportunities for their development, which involve technical, social, ethical, and other aspects. Some examples of challenges and opportunities for the development of virtual assistants are:
- Privacy: virtual assistants need to deal with the privacy of users, which involves the collection, storage, use, sharing of personal, sensitive or confidential data of users. They need to ensure that the data of users are protected, respected and consented and that users have control, transparency and access over their data.
- Security: virtual assistants need to deal with the security of users, which involves the protection, prevention, detection, correction of threats, attacks and frauds that may affect users, virtual assistants, devices and systems. They need to ensure that users have trust, reliability, integrity and authenticity when using virtual assistants.
- Ethics: virtual assistants need to deal with the ethics of users, which involves the values, principles, norms and laws that govern human behavior and society. They need to ensure that virtual assistants are fair, honest, responsible and respectful and that they do not cause harm, prejudice or discrimination to users or other parties involved.
- Personalization: virtual assistants need to deal with the personalization of users, which involves the adaptation, customization and recommendation of virtual assistants, responses and actions according to the profile, mood and context of users. They need to ensure that virtual assistants are able to know, recognize, remember and anticipate the preferences, needs and intentions of users, and offer a unique, satisfactory and relevant experience for each user.
- Interactivity: virtual assistants need to deal with the interactivity of users, which involves the communication, collaboration and cooperation between users and virtual assistants, or between users and other users, or between virtual assistants and other virtual assistants. They need to ensure that virtual assistants are able to dialogue, negotiate, coordinate and resolve conflicts with users or other parties involved, and offer a natural, fluid and efficient experience for each situation.
