1. A tactile smart watch for health monitoring and navigation of visually impaired, comprising:
a watch case comprising a tactile digital interface;
one or more tactile push buttons configured on an outer circumference of the watch case,
wherein the one or more tactile push buttons are configured to activate one or more functions associated with the tactile smart watch;
one or more touch sensitive indicators disposed on a bezel of the tactile digital interface,
wherein each of the one or more touch sensitive indicators is configured to receive one or more touch inputs from a user, and identify one or more specific actions required corresponding to the one or more touch inputs,
wherein the one or more specific actions comprises activating one or more applications in the tactile smart watch, activating one or more applications in a communicatively coupled smart device, and sensing one or more application parameters via a sensing module,
wherein each of the one or more touch sensitive indicators are configured to generate one or more haptic feedback in response to the one or more touch inputs;
the sensing module configured within the watch case,
wherein the sensing module is configured to:
receive one or more electrical signals corresponding to the identified one or more specific actions from the one or more touch sensitive indicators, and to sense one or more application parameters based on the received one or more electrical signals;
generate a first tactile feedback to monitor health of the visually impaired using a first set of sensor, wherein the first set of sensors comprises a heart rate sensor, a SpO2 sensor, and a blood pressure sensor, wherein a first set of application parameters of the one or more application parameters corresponding to the first set of sensors comprises heart rate, oxygen saturation, and blood pressure; and
generate a second tactile feedback to navigate the visually impaired based on navigational data from a GPS of a mobile device and a second set of sensors, wherein the second set of sensors comprises environmental sensor and a motion sensor; and wherein a second set of application parameters of the one or more application parameters corresponding to the second set of sensors comprises environmental condition and amount of movement of user,
wherein the one or more application parameters are communicated, via haptic feedback, numerically to the user, in a predefined sequence by a predefined duration of vibration, using the one or more touch sensitive indicators.
