ERGONOMIC STUDY OF MOBILE APPS
What is Ergonomic design in context of Mobile Applications ?
Ergonomics is the science of designing the job, equipment ,and workplace to fit the user Ergonomic Design in context of mobile applications means designing the applications so that the user can use the application comfortably without being visually , mentally or physically stressed. It takes into account of the user’s capabilities and limitations in seeking to ensure that tasks and information suit the user.
Human –Machine interaction goes hand-in hand with User interface design. With mobile quickly emerging as a viable source of web based content ,designers need to know how to adapt and keep up with user. These ‘User Centric’ designs forces us to craft interface in tune with the psychology, culture and ergonomics within the context of an audience on the go It’s not just about how the design looks , but how it feels in your hand.
The more the person have to click through screens just to enter a small amount of data ,the less enthusiastically they will be about working Reliability and speed in mobile operations and data synchronization are also decisive for the ergonomics of a software product .

When we talk of mobile interface design we often think that the big challenge of the small screen is squeezing the app into tiny quarters. In fact ,designing a handheld mobile app involves far more subtle considerations of context and ergonomics. Hoe to make the interface irresistible ? How to craft comfortable ergonomics for fingers and thumbs? How to dodge the usability gotchas of handheld devices? How to turn tiny-touchscreen constraint to your advantage?
The look of the app is important. For users, it’s the first quality indicator they see. Attractive design, clear and effective layouts that feel optimal on the user’s device, and high quality icons ,graphics and images ,send clear quality messages. Visual quality also contributes to both functionality and usability of the app. For example, legible fonts and font sizes ,and color palettes that enhances legibility, are functionally essential , not just nice-to-haves.
FACTORS AFFECTING INTERFACE DESIGN
User Interface Design
APPEARANCE OF ICONS
EASE OF ACCESS
e.g. Group Functionally related elements
e.g. Use Of Contrast Effects to improve readability
e.g. Body Constraints

CAMERA APP Consider the built in Camera application that Apple provides. The application is simple and attractive but the buttons for the application are in exactly wrong place. To take a proper picture you need to hold the phone perfectly vertical(unless you are taking the picture of the floor) .The slippery edges of the Difficulty in holding phone requires you to hold the phone firmly making it difficult to tap the camera or alternatively balance the camera precariously on your pinkie finger.
We can’t easily tap every region of the phone with equal ease .Our hand isn’t designed for this. Yes our thumb is opposable but unless it’s double jointed there will still be parts of the phone that are harder to tap. The mechanics of how you hold your phone make it much...
