Gestures Interactions: Humans naturally use gestures or gestures with voice to communicate with others. Humans can also communicate with machines where no physical contact is required. Gesture recognition software enables to communicate with a machine (Human Machine Interaction) more naturally. Speech interaction: is an enjoyable way to interact with application replacing keyboard, mouse, touch and gestures. Speech recognition software converts words spoken by the user into web search, text for form input, to specify an action to accomplish a task.

2. Touch First Design – Redefining ‘Touch-friendly’ interaction design
The usage of touch-enabled devices started a few years back and it has
become very popular these days. Without these devices it is hard ‘to live’ or
‘to think’ and it has become a part of our lives. People depend on them every
day for all sort of information and for communication. Different user groups
interact using different types of touch-enabled devices based on their
preferences, usage, comfort and lifestyle.
Companies these days plan with utmost care so that their business is
accessible from all screen sizes right from mobiles to desktop making it more
user friendly and getting it run seamlessly on the devices used by their
customers. With many alternative solutions customers can easily switch
providers if not satisfied, and retaining customers is the most difficult task in
today’s business.

3. Let’s say, if the screen size and interaction controls are small, it will be difficult
for a user to tap on it. If it is large, then it will be easier to tap but these
controls would occupy more space and leave less space for the content. This
needs to be planned on the basis of ‘what’ and ‘how’, to present content for
different devices.
Different device manufacturers have given suggestions on target sizes. These
target sizes are neither consistent with each other nor consistent with the
actual size of the human finger. Research studies say that the average width of
the index finger is 1.6 to 2 cm (16 – 20 mm) for most adults. This converts to
45 – 57 pixels, which is wider than what most mobile guidelines suggest. So
what is the solution? DESIGN for TOUCH!

4. Designing for touch means designing for fingers. Every touch target has to be
large enough to interact with and should be clearly divided without touching
accidentally on something else. (Recommended: 44px, Minimum: 32px). And if
it is text links, give a minimum invisible tap area to interact (Recommended:
44px).
Gestures (scroll, swipe, zoom and rotate) are primarily accessible to hand
movements to provide fascinating and immersive interaction experience while
doing tasks. Gestures are commonly linked to animation effects to showcase
the status and visual feedback of the action performed.
If it is a mobile browser, at times, native controls take over and may cause
conflicts in gestures. In order to avoid that, an alternative tap or click action
has to be given to interact. Thus, keeping the design simple, consistent, easy
to recognize and use.

5. Touch Free Design – Redefining ‘Touch-free’ interaction design
Humans naturally use gestures or gestures with voice to communicate with
others. Humans can also communicate with machines where no physical
contact is required. Gesture recognition software enables to communicate
with a machine (Human Machine Interaction) more naturally.
Touch free gestures are the natural body movements used as command to
operate machines which include movement of hand, finger, face, eye and
body to navigate the wide array of content with scroll, rotate, zoom, volume,
flip, change of channels, stop, pause, or play a video etc.
Gestures Interactions

6. Gesture recognition and motion tracking applications are running on
smartphones, tablets, PCs, TVs, gaming consoles and household devices. The
adoption of gesture recognition is increasing and expected to be used more in
sectors like Automotive, Entertainment, Transport, Defense, Healthcare, Retail,
etc.
Speech Interactions
Speech interaction is an enjoyable way to interact with application replacing
keyboard, mouse, touch and gestures. Speech recognition software converts
words spoken by the user into web search, text for form input, to specify an
action to accomplish a task.

7. Conversational UI’s – are the applications built with artificial intelligence called
as chatbots or invisible apps that no longer have graphical interfaces. Many
companies in the mobile space have their own apps like Apple has Siri, Google
has OK Google, Facebook has M, Amazon has Echo, Microsoft has Cortana and
so on.
By using specific commands, you can tell a system what it needs to do like
buying tickets, booking hotel, order food etc. The Interface just imitates chatting
or does things just like a real human. Going forth conversational interface will
change the way we use technology.
It is important to learn and adopt new technologies to bring in a new level of
convenience to customers.
