FIELD OF INVENTION

Embodiments of a present disclosure relates to wearable devices, and more particularly to a wearable device with a smart timer.

BACKGROUND

Wristwatches are one of the important devices for daily human usage. Conventionally, any wristwatch facilitates a user to access time as well as alarm function. Such wristwatch may also provide a timer feature. An alarm is mostly set for routine-based tasks such as waking up in morning, and the like. However, a timer is non routine based feature. For example, you set an alarm of 7 am whereas a timer of 35 minutes. The alarm and the timer usually give a sound signal at a time pre-set. The sound-based alarms or timers are almost impractical to use for setting short timers as users would not much use it because of its distractive nature, not just for the user but also for people around. Both, analog wristwatch and a digital wristwatch may be fabricated with the alarm and the timer functions.

Conventionally, the wristwatch can be effectively used to set long duration timers or alarms. The wristwatch generally lacks easy step process to help setting short duration timers such 10 mins or 20 mins. Usually, the alarm or the timer setting step process involves a long method step, that is not effective for short duration timer settings.

Furthermore, any wearable devices such as the wristwatch, and the like generally gives sound alarm irrespective of the fact that whether the user is wearing the device or not.

Hence, there is a need for a wearable device with a smart timer and a method to operate the same and therefore address the aforementioned issues. BRIEF DESCRIPTION

FIG. 1 is an exemplary wearable device 100 for setting timers, in accordance with an embodiment of the present disclosure. In such embodiment, the wearable device 100 may be a smartwatch, a smart band, an analog watch, digital watch and the like. Watches are portable timepieces, used to measure time and intervals. The wearable device 100 discloses a mechanism to enable easy setting of a timer for small duration time.

The wearable device 100 for setting timers includes a touch-based dial interface on a front casing of the wearable device 100. In one embodiment, the front casing of the wearable device 100 is circular in shape. The front casing of the wearable device 100 is formed of a back cover (as shown in FIG. 2) and a central unit 102. In one particular embodiment, the central unit 102 is fabricated with a glass cover. In such embodiment, the glass cover compactly fits over a touch-based dial interface of the wearable device 100. Furthermore, the glass cover is surrounded by a bezel around the central unit 102.

In such embodiment, the display may be an analog display (as shown in FIG. 8) or a digital display (as shown in FIG. 9). The display usually includes an hour hand, a minute hand and a second hand. The hour hand points towards hour on the wearable device 100. The minute hand points towards minute on the wearable device 100. The second hand points towards second on the wearable device 100.

The touch-based dial interface also includes a set of touch-based hour sensors 104 positioned at standard hour markers. The set of touch-based hour sensors 104 are configured to receive a first set of touch inputs from a user for setting a timer. In such embodiment, the first set of touch inputs may be provided by the user through finger touch over touch-based hour sensors 104. The touch-based hour sensors 104 comprise at least one of a touch sensitive electrode (as shown in FIG. 4) and a virtual hour markers.

The touch-based dial interface also includes a tactile switch 106 placed at an outer periphery of the front casing. The tactile switch 106 is configured to receive a second set of touch inputs from the user for setting the timer. The tactile switch 106 receives the second set of touch inputs by at least one of a continuous press, a double tap and a triple tap.

In an exemplary embodiment, suppose a timer of 15 minutes is to be set. User may press the tactile switch 106 at the circumference. With a second finger, user may touch the electrode 104 corresponding to 15 minutes (3rd indicator). Then finally, user releases both the fingers and the timer is set. A vibration pulse is generated to indicate that a timer is successfully set.

FIG. 2 is a sectional view of a back cover casing 200 of the wearable device in accordance with an embodiment of the present disclosure. The back cover 202 is fabricated with a touch sensitive device. As used herein, the term “touch sensitive device” is a type of device that captures and records physical touch or embrace on the wearable device. The touch sensitive device is configured to detect any skin contact of the user. Before ringing the alarm using sound or vibrations, the wearable device 100 detects if the user is wearing it or not. The back cover 202 of the wearable device 100 is touch sensitive. Whether the user is wearing the wearable device 100 or not, is detected by the presence or absence of skin contact respectively.

In operation, a user has to provide touch input to the required set of touch-based hour sensors 104 and the tactile switch 106 at same time and set the timer. The tactile switch 106 actuates a vibration generator for the timer. The back cover 202 of the wearable device 100 detects presence of the wrist of the user before giving vibration output. Upon detection of the wrist of the user, a vibration pulse is generated, and the user is notified about the time. FIG. 3A-B are exemplary analog wearable devices for setting timers, in accordance with an embodiment of the present disclosure. For setting a timer, the user first triggers the tactile switch 106. The user tiggers the tactile switch 106 by continuous press, double tap, triple tap and the like. In next step, user touches a touch-based hour sensors 104 from a set of 12 hour indicators or hour sensors. The touch-based hour sensors 104 are touch sensitive electrodes placed at specific hour positions. For example, to set timer for 5 hours and 45 mins, the user must first touch the touch sensitive electrode at a position that corresponds to 5 hours (5th indicator from the set of twelve-hour markers) and release the touching finger. In the next step process, the user must touch the top touch sensitive electrode (12th or Oth indicator from the set of twelve-hour markers) and swipe the touching finger towards the touch sensitive electrodes corresponding to 45 minutes (9th indicator from the set of twelve-hour markers). The steps stated helps in easy setting of the timer.

The user touches a specific electrode at a position that corresponds to 5 hours (5th indicator) and release the same finger. The user then touches the top electrode (12th or Oth indicator) and swipe the finger towards the electrode corresponding to 45 minutes (9th indicator). As the user releases the finger, and the timer is set.

The present disclosure discloses the wearable device 100 for setting the timer for small duration time. In all conventional systems, the timer setting is a time taking process and not very effective. Further standard analog watch usually does not offer such a functionality. Additionally, any smart watch generally needs wireless connectivity for setting the timer. The disclosed wearable device 100 can be used without such wireless connectivity.

The disclosed wearable device 100 design makes it easy to set timers, mainly focusing on short timers. Any user may achieve the timer setting task within one or two seconds with minimum efforts. The silent nature of the alarm or timer is that the timer does not restrict the user to use the feature in public environments.

The time setting feature in the present disclosure help people set short timers instantly and side by side also boost daily productivity as user can monitor and limit daily activities with the help of easy setting timer. Furthermore, the wearable device 100 may even have no visual indication of time. Instead, the wearable device 100 can use the touch sensitive embossments to produce haptics-based output when touched at the right location. Such a wearable device may be used by the Visually Impaired People.

The wearable device 100 may have a dial ring with hour markers. In such a situation, an outer ring at the circumference with touch sensitive tactile embossments will be used to set timers. A standard analog watch usually do not have such a functionality. A digital Light Emitting Diode (LED) watch which has a timer or alarm feature usually uses a long and complex process for setting timer. For example, a smart watch require the following actions such as raising the wrist, unlocking by pressing the button, scroll and find the application, clicking on the application, and the like. The current designed wearable device 100 uses actions such as raising the wrist, pressing the tactile button, touching the finger at selected location and releasing the finger touch. Hence, setting the timer is performed with small and simple steps using the wearable device 100.

The figures and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. For example, order of processes described herein may be changed and are not limited to the manner described herein. Moreover, the actions of any flow diagram need not be implemented in the order shown; nor do all of the acts need to be necessarily performed. Also, those acts that are not dependant on other acts may be performed in parallel with the other acts. The scope of embodiments is by no means limited by these specific examples.
