What is Tangible User Interface?

The interface that an individual interacts with digital information through the physical surroundings this interface is referred as a tangible user interface. Initially, it was referred as Graspable User Interface that is now considered as outdated (Eckhardt, 2016). The concept with the tangible user interface is to have a direct connection between the system and the way to regulate it over physical influences by having basic direct relationship or meaning, which links the physical operations to the behaviors, which they activate on the system.

Advantages

• Tangible user interfaces have new physical activities to the collection of computer-based learning exercises.
• The coupling of augmented reality with TUI (the framework projects data over physical antiquities) takes into account a nearby mapping between digital output and tangible input, between the physicality of an object, the controls it manages, and the abstraction of representation.
• A face-to-face is  collaborative is supported by TUI, enabling numerous clients to communicate with the SYSTEM while teaming up with each other

Disadvantages

• Some diverse points of view on directing physical material recommend that TUI can similarly prompt no or negative learning results.
• Manipulative are more often than not translated as representing something unique, and the challenge to view them as symbols cause these mix outcomes.
• The risk of physical material is to compel reflection and abstract reasoning by obstructing the student in an active mode.

Ubiquitous computing is an idea in programming and software engineering where computing is made to appear whenever and all around. As opposed to desktop processing, ubiquitous computing can happen using any gadget, in any area, and in any arrangement. A client interacts with the computer, with an existence of many forms, comprising laptop computers, terminals and tablets in day-to-day objects, for example, a pair of glasses and refrigerators.

Advantages

• Nevertheless, ubiquitous computing makes numerous everyday activities quick and more cost-productive.
• Utilizing the data collected from sensors, the computerized home can always change lighting and temperature to keep up a maximally comfortable condition.

Disadvantages

• Ubiquitous computing could make moral dilemmas involving client assent. With a couple of expectations, people have customarily utilized computer frameworks consensually.
• However if the computer frameworks end up persuasive in all aspects of everyday life, this could drive individuals to engage in without assent.
• It is possibly hard to implement ubiquitous computing whereas at the same time retaining adequate security assurances. 

Augmented reality is an indirect or direct live perspective of a physical, real-world situation whose components are “enlarged” by computer-created perceptual data, in an ideally over numerous sensory modalities, comprising haptic, visual, audio, olfactory and somatosensory. The overlaid sensory data can be useful (i.e. added substance to the indigenous habitat) or ruinous (i.e. concealing of the indigenous habitat) and is spatially enlisted with the physical world to such an extent that it is seen as an immersive aspect of the real situation.

Advantages

• AR one gives clients an instrument for making the content that they could not initially do without anyone else’s input.
• An opportunity to make something extraordinary and in this manner to express one’s individuality is much more captivating than standard media content.
• The informal exchange and social sharing rise the acquisition of new clients.

Disadvantages

• Current execution levels in terms of how first the current iPhone or comparable touch gadgets such as the Google G1 will take some generations to brand Augmented Reality achievable as a common interface approach open to the general population.
• Privacy control can turn into a greater issue than with the present data immersion levels.
• Content may narrow or obscure a user’s tastes or interests. Such as, having knowledge where McDonald’s or Starbucks is in Paris or Rome won’t intrigue clients as much as “off the beaten track data” that you may search out for adventures experiences. 

Haptic alludes to detecting and control through touch. By utilizing special outputinput gadgets (data gloves, joysticks, or different gadgets), clients can get feedback from computer software in form of feelings in the hand or various parts of the body. Mixing this with a visual display, in this technology haptic can be utilized to train peoples for assignments requiring hand-eye, for example, surgery and space ship moves.

Advantages

• Correspondence is focused on touch and the computerized world can act like the real world.
• Working time is lessened since objects can be manipulated, captured rescaled and altered electronically.
• Medicinal field test systems permit surgeons to practice electronically, building the confidence in the process prior working on breathing patients.
• Haptic software and hardware, the designer can manipulate the part and feel the outcome, as though he/she were dealing with the physical object.

Disadvantages

• The exactness of touch requires a lot of design advancement. With just a sense of touch, a warning cannot be delivered by haptic interfaces.
• Haptics applications can be to a great degree be complex, requiring particular impressive processing power and specialized hardware.
• The many haptic implies the complexity depends on the fixed installation of equipment and not portable.
• Troubleshooting issues, these are entangled since they include constant information examination.
• When the objects are being controlled in haptic are virtual, customize a compelling cooperation with the gadget needs all physical properties and forces included in the application. Accordingly, costs for haptic activities can be significant.

Wearable technology, wearable’s, popular innovation, wearable gadgets, tech togs, or mold hardware are smart electronic gadgets (electronic gadget with micro-controllers) which can be worn on the body as accessories or implant.

Advantages

• More prompt: The use of numerous applications regularly requires some preparing of time.
• Enables one to remain better drew in with the existing condition.
• The discreetness of gadgets like Google Glass could likewise lend the item to some less savory applications also.
• A standout amongst the fascinating ways that convenient innovation has advanced is in the area of touch.

Disadvantages

• Unmistakably, wearable technology can do bounty that standard cell phones and tablets cannot do, yet they likewise have some serious confinements.
• Unlike the average phone or tablets, the wearable technologies are smaller.
• This type of technology is one of the things that will change in time as individuals get used to its quality; however for a long time to come individuals who use wearable technologies will be viewed as outcasts.

Proxemics Interaction visualizes interactive computer frameworks that exploit individuals’ and gadgets’ spatial connections (proxemics) to offer more seamless and natural interfaces with ubicomp technology.

Advantages

• The positioning of wireless, which is used by the technologies to offer a distinctive identifier of the tracked device, specifically a hardware address.
• The concept of having small devices committed to offering proxemics input allows other interesting chances as well.
• Low cost

Disadvantages

• correcting and avoiding mistakes
• Challenge in establishing connections
• Challenge in managing privacy and security
