The Band Wireless model is designed to be used in facilities for reliable danger notification and haptic feedback in theme parks. It can be worn anywhere on the body, including the arms, legs, and torso. It incorporates the ESP32 wireless module and can communicate with Wi-Fi and other major wireless systems. The internal mechanism is almost identical to the Band model, with a built-in battery and wired input support, but audio output is omitted.

This product requires programming and is intended for developers. It is necessary to write firmware and voice data to Hapbeat using VSCode. If you need low latency (a few milliseconds) communication, we recommend using ESP-NOW, but you will need a separate transmitter using an ESP32 microcontroller (e.g., M5Stack).

This value includes the amount of rubber extension. In addition, the enclosure's width, 5.4 cm, is added.
In addition to this value, the width of the enclosure (4.4 cm) and the length of the thread ejected from the enclosure (2-3 cm per side) are also added.

The reference price is for the hardware only. We will support the introduction of general-purpose firmware provided by our company, but individual development costs are not included. We also offer system development services, so please get in touch with us if you are considering introducing the system to your facility.

Development flow

The basic flow of the system is that Hapbeat stores the sound data, and the external transmitter sends text commands (e.g., '0,0,0,0,0,0,50,50,0') for playback via Wi-Fi, ESP-NOW, etc. Implementation is quite easy if the source code of a system is editable. For example, in the case of Unity, the developer can realize haptic feedback by adding simple code that sends text messages to a transmitter via USB serial, just like adding sound effects.
