[0134] Each identified emotion is shared between connected users, which provides benefits for both users:

[0135] - The emotion “giving” will receive actionable insights to improve self-awareness, manage stress and build stronger relationships.

[0136] - The emotion “receiving” will enhance mental stimulation and feel stronger connections.

[0137] This use case may further include broadcast to multiple family members, enabling shared emotional presence during important moments.

[0146] This configuration enables intimate emotional communication between individuals, suitable for personal relationships, remote support, or therapeutic applications.

[0147] Use Case 2: Content-Synchronized Emotional Feedback

[0148] In another embodiment, the system comprises a wearable device as described above and a content source device, such as an audio player, video player, gaming system, virtual reality system, or mixed reality system. In this embodiment, the processor of the wearable device is configured to receive emotional or contextual signals derived from content presented by the content source device. Such signals may be generated by a transmission platform configured to analyse content and to map emotional states, events, or intensity levels within the content to corresponding haptic outputs. The wearable device generates haptic outputs synchronized with emotional states associated with the content. In some embodiments, such synchronized haptic outputs are delivered simultaneously to multiple users to create a shared emotional experience.

[0149] In an example of this use case, a user watches a dramatic movie scene.

[0150] a. Emotion: They seek deeper immersion and emotional engagement in storytelling experiences.

[0151] b. Problem: Standard viewing lacks sensory interaction, limiting emotional impact. c. Solution: The smart watch synchronizes with on-screen moments, providing tightening, vibrations, warmth that amplify the emotional intensity of dramatic scenes.

[0194] Paired Devices (104): Devices linked to specific users for direct emotional interaction. These may include smartwatches, haptic bands, or mobile apps.

[0195] Endpoints (105): Devices configured to receive broadcast or synchronized emotional signals.

[0196] Third-Party Systems (103): External platforms that may provide biometric data or authentication services. These systems interface with the transmission platform and cloud infrastructure.

[0197] Signal flow is indicated by arrows connecting each module, showing the progression from source device through transmission and routing to endpoints and paired devices. This architecture supports both one-to-one and one-to-many emotional transmission, with cloud-based scalability and third-party integration.

[0198] The invention accordingly provides a means to enhance moments as they are experienced by the user. Furthermore, the features serve to augment meaningful experiences by suggesting actions or creating special moments (e.g., virtual hugs or kisses and synced heart rate vibrations).The invention provides a dual focus on both emotional and physical wellness, in that it:

[0199] • Tracks physical metrics such as steps, calories and sleep quality alongside emotional health, making it a holistic wellness companion.

[0200] • Combines fitness and emotional data to provide insights into how physical health influences emotional well-being and vice versa.

[0201] The wearable device and system of the invention may thus operate in multiple modes, which include the previously described Use Cases of:

[0202] 1. Human-to-Human (paired);

[0203] 2. Content-to-Human (media synchronisation); and

[0204] 3. Human-to-Many (broadcast).

[0205] The emotional detection algorithms described herein may be used to generate haptic outputs not only on a paired device but also across multiple recipient devices, enabling shared emotional experiences.

[0206] The system may define “moments”, which are time-bound emotional transmission sessions initiated by the source user. These moments may correspond to:

[0207] • live events (performances, races, speeches),

[0208] • recorded content,

[0209] • personal emotional expressions,

[0210] • shared experiences among groups.

[0211] Mobile devices or other embodiments of the endpoints may render haptic outputs using vibration motors, which can be combined with screen animations, light pulses, or audio cues (for example).

[0212] In the system architecture, endpoints refer to the final devices or interfaces that receive and render emotional or biometric signals. They are the destination nodes in the transmission chain, where the user experiences the output.Endpoints are thus devices:

[0213] • Configured to receive emotional signals from a source (via cloud or routing module);

[0214] • Capable of rendering feedback — haptic, thermal, visual, or auditory; and • May be paired (one-to-one) or broadcast (one-to-many).

[0215] Some examples of these endpoints include the types listed below along with functionality options:

[0216] Smartwatches - Vibration, thermal pulses, strap tension;

[0217] Haptic wristbands or straps - Pressure modulation, pulse mirroring;

[0218] Mobile devices, smart phones or tablets - Visual cues, vibration, audio feedback;

[0219] AR / VR devices or headsets - Immersive emotional rendering (e.g., warmth, heartbeat simulation);

[0220] Smart rings or patches - Discreet biometric feedback; and

[0221] Companion apps - Visualized emotional states, synced with wearable feedback.

[0222] The platform may authenticate recipients, manage session access, and synchronize outputs across all devices.

[0223] The current competitors in the smart watch wearable industry do not offer the features of the invention which link haptic connections to emotions in the manner set out.

[0224] The device of the invention will find application with, amongst others, emotionally connected individuals, technology enthusiasts and those seeking to establish deeper connections and experiences.

[0225] Depending on how and why customers interact with wearable technology, the features of the smart watch will be tailored for usage scenarios and marketing approaches to meet the expectations of heavy and light users alike, ensuring an engaging and impactful experience.The smartwatch aims to enhance moments through real-time digital inputs and realtime haptic feedback, offering vibrations, lighting, temperature changes and mechanical band adjustments to simulate emotional and physical gestures. This will in turn serve to create an immersive connection experience for users, aligning with music, movies, performances, events, or personal interactions.

[0226] The invention serves to enable an emotional connection through innovative technology, empowering individuals to (amongst others) create, share and cherish meaningful moments of love, kindness and deeper connections. In this manner, by integrating emotion and technology, it is expected to enhance human relationships and bridge distances, strengthen bonds and / or make shared moments more heartfelt and impactful.

[0227] A person skilled in the art will appreciate that a number of variations can be made to the features of the embodiments of wearable device and feedback system and method as described and / or referred to above without departing from the scope of the invention disclosed.

[0228] A person skilled in the art will also appreciate that wearable devices within the scope of the invention may take a variety of forms and be selected from many examples of alternative designs or for alternative applications (such as rings, bands or glasses).
