There are several ways to develop a noninvasive BCI, such as EEG (electroencephalography), MEG (magnetoencephalography), or MRT (magnetic resonance tomography) [1]. Among these, EEG-based BCIs are the most preferred for studying due to their noninvasive nature and relatively low cost. There are various easy applications of BCIs, including: 1. **Medical and rehabilitation**: BCIs can help individuals who have lost the use of their limbs, require assistive devices, or are unable to speak. They are often used for rehabilitation after stroke or injury[6]. 2. **Neuroergonomics**: BCIs can be used to monitor cognitive workload, fatigue, and attention levels in various settings, such as aviation, driving, and workplace environments[2]. 3. **Gaming and entertainment**: BCIs can be integrated into gaming systems and virtual reality environments, allowing users to control games and interact with virtual worlds using their brain signals[5]. 4. **Education and training**: BCIs can be used to monitor students' cognitive states, such as attention and engagement, during learning activities. This information can be used to adapt teaching methods and materials to better suit individual needs[8]. 5. **Affective computing**: BCIs can be used to detect and analyze users' emotional states, which can be applied in areas like human-computer interaction, marketing, and mental health monitoring[5]. 6. **Security and lie detection**: BCIs can be used to detect deception by monitoring brain activity during questioning, potentially providing a more accurate and less invasive alternative to traditional polygraph tests[8]. 7. **Art and creativity**: BCIs can be used to create unique artistic experiences by allowing users to generate music, visual art, or other forms of expression using their brain signals[8]. Despite the numerous applications, there are still challenges in BCI development, such as improving signal processing, enhancing user training, and addressing ethical concerns[5]. However, as research and technology continue to advance, we can expect to see even more innovative and accessible applications of BCIs in the future.

The technology has potential applications in various fields, including rehabilitation, affective computing, robotics, gaming, and neuroscience[13]. Although there is no single "easy" application that can generate the most revenue, several applications show promise in terms of market growth and potential impact. Some notable applications of BCIs include: 1. Medical and rehabilitation: BCIs can help individuals with paralysis regain control of their limbs, communicate using computer-based systems, and operate assistive devices[3]. They can also be used for neurological rehabilitation, helping patients recover from strokes or injuries[16]. 2. Neuroprosthetics: BCIs can be integrated with prosthetic devices, allowing users to control them using their thoughts[2]. This can significantly improve the quality of life for amputees and people with mobility impairments. 3. Gaming and entertainment: BCIs can be used to create immersive gaming experiences, where players control in-game actions using their thoughts[12]. This can open up new possibilities for game design and user interaction. 4. Education and research: BCIs can be used in educational settings to study brain activity and cognitive processes, as well as to develop new teaching methods and learning tools[5]. 5. Military applications: BCIs can be used to control drones or other military equipment hands-free, enhancing soldiers' capabilities on the battlefield[3]. 6. Smart environments: BCIs can be integrated with smart home systems, allowing users to control their environment using their thoughts[12]. The global brain-computer interface market size was valued at USD 1.74 billion in 2022 and is expected to grow at a compound annual growth rate (CAGR) of 17.5% during the forecast period[2]. This growth is driven by factors such as increasing prevalence of neuroprosthetic conditions, a rising global geriatric population, and rapid technological developments facilitating communication and movement in paralytic patients[5]. As the technology continues to advance and its applications expand, the potential for revenue generation in the BCI market will likely increase.
