FIN-WEAR THE WORLD

FIN-WEAR THE WORLD

CHAPTER 1INTRODUCTIONFIN- wear the world is a real life buddy for every individual to do their digital interactions as natural as possible. Fin is a trendy gadget that can be worn on the thumb and makes the whole palm as a digital touch interface. Fin is one of the top 15 startups in the world at TechCrunch Hardware Battlefield in the year 2014. Fin is as shown in the Figure 1.1.

Figure 1.1: FIN-Wear the WorldWearable technology has a long way to go when it comes to taking the next big leap into the future of gadgets and gizmos. And by far what it has been seen in the wearable technology market is quite impressive. Another new entrant in this demanding wearable technology sphere is Fin ring by RHL Vision, a visionary Indian tech start-up looking to transform the complexion of current gadget market. As the name itself suggests, Fin is a wearable ring that gives the power to morph hand into a digital touch interface which is gesture controlled to achieve any kind of action. The device acts like Hotkey for certain specific function as it has built-in sensors to track movement in relation to the palm, virtually turning it into a segment of different areas for different input. For example while typing in the whole palm turns into a numeric keypad. The ring is connected to other gadgets like Smart TV, Smartphone, desktop, dashboards etc. using Bluetooth connectivity and pre-programmed gestures control functions like controlling volume, sending text, dialing phone numbers, taking photos or playing games.Gestures are an important aspect of human interaction, both interpersonally and in the context of man-machine interfaces. A gesture is a form of non-verbal communication in which visible bodily actions communicate particular messages, either in place of speech or together and in parallel with words. Gestures interface with computers using gestures of the human body, typically hand movements. Gesture recognition is an important skill for robots that work closely with humans. Gesture recognition is especially valuable in applications involving interaction with human/robot for several reasons. Gestures include movement of the hands, face, or other parts of the body. In the military, the air marshals use hand and body gestures to direct flight operations aboard aircraft carriers. Fin uses hand gesture recognition. Hand gesture recognition is one obvious way to create a useful, highly adaptive interface between machines and their users. Hand gesture recognition technology would allow for the operation of complex machines using only a series of finger and hand movements, eliminating the need for physical contact between operator and machine.The possibilities are endless as Fin ring can be connected to any iOS, Android or Windows compatible device of the users choice, provided app developers make applications for the same. Fin runs on a lithium ion battery that is recharged via Micro-USB port and lasts almost two months on normal usage. Once you wear it the world is in your palm and once app developers get to work on exploring the possibilities of Fin we can expect.

CHAPTER 2FEATURES OF FINFIN wear the world has different features which enables it to be the best wearable tech. A new gesture-based wearable transmitter turns the palm into a touch interface. The ring shaped transmitter called Fin is worn on the thumb and uses Bluetooth technology to communicate with different electronic devices. The portable device enables to control up to three electronic devices such as smart phones, car radios and smart TVs using only swipes and taps. The device can control the volume on a TV, change the channel, adjust AC in the car and even let users text or dial a number without touching their phone. The ring also works as a remote control on a number of Smartphone functions like accepting or rejecting calls, using the phones camera, and controlling the media player. FIN is made up of flexible, durable, waterproof and dustproof material. The ring shaped wearable FIN is charged wirelessly. The features of Fin are as listed below in the Figure 2.1. Fin is compatible with three different types of devices. FIN can be interfaced with three electronic devices having Bluetooth technology. The electronic devices can be the smart TV, Smart watches, music systems and gaming devices. The Figure 2.1 shows the different types of devices that Fin is compatible.

Figure 2.1: Electronic devices compatible with fin.

Fin is compatible with Smart TV, head mounted devices, music system in cars, AC control in car, smart phones. Among these devices any three can be interfaced with a single Fin and can perform any action in them just by using the thumb and the palm.2.1 Gesture interaction on palmFIN worn the thumb turns the whole palm into a gesture interface which enables the palm to interact with the electronic devices that has been interfaced with it. The electronic devices to be interfaced with Fin should have Bluetooth technology. The Figure 2.2 shows the thumbs gesture interaction with the palm.

Figure 2.2: Gesture interaction on palm

2.2 Recognizes each division of the fingerFin can uniquely recognize each segment of the fingers and can convert the palm into a numeric keypad. For example, tap using the thumb on the index finger to make the smart phones silent mode toggle On/Off while the smart phone is in the pocket of the user. The different segments of the finger recognition are as shown in the Figure 2.3.

Figure 2.3: Segment recognition by FIN2.3 Fin makes your palm as numeric keypadsFin makes palm as numeric keypads and fingers as hotkeys. Fin makes fingers as virtual keyboard as a touch-typing device that does not have a physical manifestation of the sensing areas. That is, the sensing area which acts as a button. The Figure 2.4 shows the fin worn on the thumb ring makes the palm to act as virtual keypads. So a sensing area could for example be realized with photo-electric sensors, active finger tracking methods, or a touch pad. The latter is different from a keypad as it does not have a-priori designated areas for buttons. Virtual keyboards that employ discrete sensing areas for each symbol (rather than chording methods) inherently allow for realization of a soft keyboard. To mention are soft keyboards which can dynamically change the key arrangement for different users, situations, or even from keystroke to keystroke. Often times they also provide keys that produce a sequence of characters per key press. This benefit is of particular interest to virtual keyboards as they might combine a projection method with the input detection technique, thereby alleviating the need to switch the focus of attention from display device to a physically separate input device.

2.4 Fashionable, waterproof, dustproof and durableFIN when worn on the thumb looks very stylish. The Fin worn on thumb is as shown in the Figure 2.5. Fin is made up of waterproof and dustproof material. This feature of Fin makes it very durable. It is also flexible and the size can be increased or decreased to the necessary requirement of the user.

CHAPTER 3IMPLEMENTATION OF FINThe designing of FIN includes the hardware description section and the working of FIN. Each and every segment of every finger is meant for some application like each and every finger on the palm is meant to target an individual gadget. The surgical stainless steel and allergy-free Smarty Ring is 13mm wide and 4mm thick, and comes in different ring sizes, from size 5 to size 15. Apart from promising a 24-hour battery life, it also has wireless charging compatibility, and ships with a wireless charger. 3.1 Hardware Description The hardware used in order to design Fin includes the following and the Figure 3.1 shows the hardware components.

Microcontroller Optical Sensor Motion Sensor Bluetooth 4.0 Battery

Figure 3.1: Components of Fin

3.1.1 MicrocontrollerMicrocontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. The microcontroller used in FIN is as shown in the Figure 3.2. The Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded application. Figure 3.2: Microcontroller ATMEGA32Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems.Microcontrollers may use four-bit words and operate at clock rate frequencies as low as 4 kHz, for low power consumption (single-digit mill watts or microwatts). They will generally have the ability to retain functionality while waiting for an event such as a button press or other interrupt; power consumption while sleeping (CPU clock and most peripherals off) may be just nano-watts, making many of them well suited for long lasting battery applications. Other microcontrollers may serve performance-critical roles, where they may need to act more like a digital signal processor (DSP), with higher clock speeds and power consumption.

3.1.2 Optical SensorAn optical sensor is a device that converts light rays into electronic signals. Similar to a photo resistor it measures the physical quantity of light and translates it into a form read by the instrument. The optical sensor used in FIN is as shown in the Figure 3.3. Usually, the optical sensor is part of a larger system integrating a measuring device, a source of light and the sensor itself. This is generally connected to an electrical trigger, which reacts to a change in the signal within the light sensor.

Figure 3.3: Optical Sensor A system for detecting infrared radiation using infrared sensors includes the infrared source such as blackbody radiators, tungsten lamps, and silicon carbide. In case of active IR sensors, the sources are infrared lasers and LEDs of specific IR wavelengths. Transmission medium used for infrared transmission includes vacuum, the atmosphere, and optical fibers. Optical components such as optical lenses made from quartz, CaF2, Ge and Si, polyethylene Fresnel lenses, and Al or Au mirrors, are used to converge or focus infrared radiation. To limit spectral response, band-pass filters are ideal. The infrared detector completes the system for detecting infrared radiation. The output from the detector is usually very small, and hence pre-amplifiers coupled with circuitry are added to further process the received signals.

3.1.3 Bluetooth 4.0Bluetooth 4.0 is designed to be more intelligent about managing those connections, especially when it comes to conserving energy. The new generation of Bluetooth tech places less emphasis on maintaining a constant stream of information. Instead, it focuses on sending smaller bits of data when needed and then puts the connection to sleep during periods of non-use. When two 4.0 devices are paired, they waste less battery power because the connection is dormant unless critical data is being shared. With the previous generation of Bluetooth, it was best to shut down your hardware when it was not in use. Now the Bluetooth Special Interest Group estimates between 1 and 2 years of battery power in some devices with Bluetooth 4.0. Its Bluetooth 4.0 technology lets the user always get real time updates including incoming and outgoing call notifications, alerts for text and email messages, real time updates from Facebook, Twitter, Hangouts and Skype.Bluetooth 4.0 or Bluetooth Smart gives the standard a brain transplant. The new specification uses improved technology that helps everyday gadgets stay paired longer while using less power. Bluetooth 4.0 enables a new class of gadgets such as fitness trackers, medical devices, and key fobs for your car, and even home lighting controls. Bluetooth Smart gadgets can also remain paired with Smart Ready devices even when theyre not used for hours or days at a time. Bluetooth 4.0 emphasis on wake and sleep modes, Smart peripherals that arent in use can remain in sleep mode indefinitely; they can also wake from that sleep mode in an instant, paired and ready to share data with a Smart Ready tablet, notebook, or smart phone.For instance, a heart monitor can be worn for hours yet only send data to a Smart Ready smart phone when a heart rate reaches a certain number of beats per minute during exercise. Likewise, a wireless thermometer can remain paired for days, but it will send temperature readings to a notebook only when that device is used to take a childs temperature. Bluetooth 4.0 wireless device-to-device technology used in FIN that offers significantly lower power consumption. Also referred to as Bluetooth Low Energy, Bluetooth 4.0 achieves its reduced power consumption by enabling devices to remain paired, or connected to each other, without requiring a continual stream of data to be transferred between the devices. Hence Bluetooth 4.0 is the best communication technology that can be used in FIN.3.1.4 Motion Sensor An inertial measurement unit or IMU the motion sensor used in FIN is an electronic device that measures and reports on a thumbs velocity, orientation, and gravitational forces. Recent developments allow for the production of IMU-enabled GPS devices. An IMU allows a GPS receiver to work when GPS-signals are unavailable, such as inside buildings, or when electronic interference is present. The motion sensor used in FIN is as shown in the Figure 3.4 Figure 3.4: IMU the motion sensor used in FINAn inertial measurement unit works by detecting the current rate of acceleration using one or more accelerometers, and detects changes in rotational attributes like pitch, roll and yaw using one or more gyroscopes. And some also include a magnetometer, mostly to assist calibrate against orientation drift. The term IMU is widely used to refer to a box containing three accelerometers and three gyroscopes and optionally three magnetometers. The accelerometers are placed such that their measuring axes are orthogonal to each other. They measure inertial acceleration, also known as G-force. The motion sensor IMU (Inertial Measurement Unit) is used as motion detector in FIN. Whenever thumb is swiped on the palm the motion of the thumb is detected by this motion sensor. This motion sensor calculates the distance covered by the thumb on the palm and sends signals to the microcontroller which will be programmed earlier for the particular distance.

3.1.5 BatteryFIN comes with its own wireless charging base, which can be used to charge the wearable along with a compatible Smartphone. . In terms of battery life though, we dont expect too much from a ring, but the campaign says it will deliver 24-hour battery life, which sounds rather neat to us considering the size. At the moment, it is said to be compatible with Android and iOS devices, as long as they have Bluetooth 4.0 capabilities. The Figure 3.5 shows the FIN being placed on smart phone for charging when the smart phone is being charged using the usual charger just place the FIN on the smart phone the FIN automatically gets charged.

Figure 3.5: FIN placed on smart phone for charging

CHAPTER 4WORKING OF FINFIN operation is mainly dependent upon the gestures that are made using the thumb since it has the capability of multiple cable identity. The Figure 4.1 shows the thumb joint which is also called trapeziometacarpal joint is an ideal joint gesture computing. For Each and every segment of every finger is meant for some application like each and every finger on the palm is meant to target an individual gadget. The surgical stainless steel and allergy-free Smarty Ring is 13mm wide and 4mm thick, and comes in different ring sizes, from size 5 to size 15. Apart from promising a 24-hour battery life, it also has wireless charging compatibility, and ships with a wireless charger.

Figure 4.1: Thumb joint is ideal for gesture computing4.1 Prototypes of fin The fin device has undergone many changes in its structure before arriving at the stylish design. The Figure 4.1.1 shows the 1st prototype of fin which has bigger in size.

Figure 4.1.1: First prototype of finThe figure 4.1.2 shows the second prototype of fin which is of the size of a coin. The size is reduced much better than the first prototype.

Figure 4.1.2: Second prototype of finThe figure 4.1.3 shows the third prototype of fin which is wearable to the thumb ring. Figure 4.1.3: Third prototype of finThe figure 4.1.4 shows the final design of fin which is small in size compared to other prototypes of fin. Final design of fin looks very stylish worn on thumb for both boys and girls. The waterproof Bluetooth-enabled ring allows users to check alerts from their smart phone and manage calls right from their finger. A companion app can be used to configure the alerts the use wishes to receive and the rings function. It can be used to trigger apps on the smart phone, such as the camera or switching profiles. The figure 4.2 shows the algorithm of working of the fin. When user inputs a gesture, the fin wore on the thumb detects the gesture and deduces it into signals and passes it to the device that is interconnected with the fin. The device performs the task inputted by the fin and gives the output. Swiping your thumb down your index finger, for example, could turn your phones volume down.

User: Inputs a gesture When the fin detects a gesture, it sends that command off to your connected device, be it a smart phone, TV, or another wearable device. By tucking an optical sensor into a small ring placed around your thumb, the Fin is able to detect swipes and taps across your hand.

FIN detects the gesture, deduces it into signals & passes it to the device (ex: smart phone)

Figure 4.2: Working algorithm.When you dial the numbers from your palm, Fin can be used to attend the calls. Dedicated music controls on the ring lets the user control playback of songs on the users smart phone. Smarty Ring also acts as a phone finder. So if the user walks more than 30 feet away from their phone, the ring will beep to let the user know that they left their device behind. According to the Indiegogo campaign, Smarty Ring will also deliver real time updates from Facebook, Twitter, Hangout and Skype. The ring can be used to read Emails. Smarty Ring can be attached with phones which are based on Android or IOS operating systems. To set up Smart ringthe user needs to download an application in their smart phone, after which their phones settings such as brightness lid, beeper volume and speed dial, can be adjusted by using Smarty Ring.Fin is also used in biometric systems and even for finger print detection. It is very useful for blind people in order to operate their electronic devices very easily. In future it is even enhanced for home purposes like locking.

It is small in size and fashionable. Wireless technology is used for charging FIN.5.2 Disadvantages The disadvantages of FIN-wear the world are as listed below: It is expensive. The user gets lazier. User might get confused to recognize the different segments of finger for different applications. The electronic device to be interfaced with FIN should compulsorily have Bluetooth 4.0 technology.

CHAPTER 6APPLICATIONS The applications of FIN are as listed below: The FIN will make your palm as a touchpad that enables the disabled people to interact with smart phones (attending the calls, SMS). FIN control the physically disabled chair with a ease. FIN can help physically challenged people to become more independent and self-reliant. A single swipe on the palm using FIN can change the music track in the users smart phone. It can be used to change the smart TV channel or increase/decrease the volume by a single swipe and bulky remote controllers can be avoided. FIN can be used instead of joysticks for gaming purposes. It can be used to change slides during presentation with just a single swipe. User can answer a call or vary the AC while driving the car without touching the phones or the remote. FIN can control your car from being your cars key to controlling your phones while driving. FIN can control other car utilities like window glass, wiper etc.6.2 Future goalsThe future goals of fin are listed below Adding more enhancements to Fin like unique user authentication. Assembly and complete kit. Integration and support. Casing and packaging. Shipping. The fund being collected would be invested in the following fields like funding for materials cost, hardware design etc.

CHAPTER 7CONCLUSION AND FUTURE ENHANCEMENT7.1 ConclusionPeople in todays world are becoming busier, but still they are wasting a lot of time interacting with their smart devices. Therefore Rohildev Nattukallingal, the founder of the Kochi-based RHL Vision Technologies, the startup behind Fin. Fin removes this interaction gap by allowing users to quickly interact with those devices. While everyones talking about Google Glass or smart watches being the wearable tech of the future, not many have considered that something smaller could be just as useful. Thats the idea with the Smarty Ring, which displays all users phones notifications so that the user dont have to keep pulling out the phone to check whats going on.In addition, it can accept or reject incoming calls but youll need to pick up your phone for the call itself, make outgoing calls to preset numbers, trigger the camera, show the time, and control music. And it beeps when your phone is more than 30 meters away from you, so it also serves as a theft/loss tracker. Its all configurable via a mobile app. Smarty Ring brings wearable tech to your finger Hence FIN-wear the world is the next fashionable and less expensive wearable technology.7.2 Future goalsThe future goals of fin are listed below Adding more enhancements to Fin like unique user authentication. Assembly and complete kit. Integration and support. Casing and packaging. Shipping. The fund being collected would be invested in the following fields like funding for materials cost, hardware design etc.
