Let's continue to understand the requirements and importance of each feature by introducing the product parameters and technical features of the NearHub Interactive Whiteboard.
1. Microphone
Incorporating a high-quality microphone is crucial for enabling seamless communication during video conferences, presentations, and collaborative sessions. A microphone with noise-canceling capabilities ensures clear audio transmission, even in noisy environments.
The primary purpose of the microphone is to convey the voices of those present to distant listeners, facilitating seamless communication between remote and proximate participants. Additionally, when integrated with video, it ensures precise capture of the primary speaker's voice. These aspects are pivotal in ensuring the smooth progression of meetings, requiring the microphone to have good audio pick up ability, strong noise cancellation ability and sound processing ability.

||
|
Pick up range |
180°horizontal pick-up angle |
8 meters pick-up distance |
|
The NearHub Board screen features a 24-array microphone. Its sound sampling rate is 48 kHz, and the sound sampling rate in the conference is 16 kHz (the sound sampling rate is known as 8k, 16k, 32k, 48k. The higher the sampling rate, the greater the information obtained, the stronger the sound source tracking ability, and the sampling rate of 16k in the session field is excellent). Compared to the 8 array or 12 array microphones, the 24 array microphone has a higher accuracy of sound source positioning and a better beam-forming effect. The effect of beam formation is of great help for noise reduction and echo elimination. |

|
Beam-forming |
Direction of Arrival-Speaker Tracking |
Full-duplex |
|
In accordance with the setting of the conference room or speech environment, the NearHub microphone produces 5 beam-forming within its lateral capture range. These are then categorized from a side perspective of 20 degrees. Essentially, this delineates a precise coverage area for sound source localization spanning 140 degrees. In instances where multiple individuals are speaking, the person with the loudest voice is prioritized for localization, facilitating rapid switching at the millisecond level. Hybrid meetings, blending remote and in-person participation, leverage full-duplex technology, ensuring seamless communication between individuals in distant and nearby locations. Attendees present at the physical venue can issue straightforward directives like "stop" or "wait," swiftly transmitting them to remote participants. This approach aims to replicate the immersive experience of in-person meetings for those joining remotely. |
||
|
Post Processing |
||
|
NearHub Interactive whiteboard undergoes comprehensive sound refinement in its post-processing phase, ensuring that the resultant sound maintains its richness, comfort, and pleasantness even after noise reduction processing. |

|
DRC - Dynamic Range Compression |
AGC - Automatic Gain Control |
|
|
Moreover, concerning auditory comfort, the NearHub board integrates Dynamic Range Compression (DRC) and Automatic Gain Control (AGC) functionalities into the audio algorithm. The DRC promptly addresses abrupt nearby shouts, high decibel sounds, and urgent noise mitigation, ensuring participants remain undisturbed by startling or excessive disruptions.The Automatic Gain Control (AGC) functionality further enhances the experience by maintaining stable volume levels regardless of the speaker's proximity, thereby ensuring a consistent and optimal auditory experience for remote participants. |
||
2. Camera
A built-in camera facilitates video conferencing, remote collaboration, and document scanning, allowing participants to engage effectively regardless of their physical location. Cameras with AI mode, can further enhance the meeting productivity and participants engagement.

The picture of each participant is individually framed and stitched together on the screen, so that the speech, expression and action of each participant can be seen. Currently, gallery view supports up to 6 participants image splicing. |
|
Auto Framing |
Automatic view, focus, frame all the conference room participants, and then placed in the center of the picture, no need to manually adjust the direction and focal length of the camera. |
|
Speaker Tracking |
Speaker Tracking must be complemented by the sound source localization (Direction of Arrival - DOA ) feature of the microphone. Through DOA, the microphone automatically identifies the primary beam and relays the signal to the camera. Upon receiving the signal, the camera autonomously adjusts its focus to track the speaker, thus achieving speaker tracking. |
3. Whiteboard Write Latency
Low latency in whiteboard functionality is essential for real-time annotation and brainstorming sessions. Minimal delay between touch input and on-screen response ensures smooth and natural interaction, enhancing the overall user experience.
