Problem 1 The display features are not in the same priority. They should be re-arranged with hierarchy Priority 1 Priority 2 Priority 3 Priority 4

Problem 2 The position of each button is too far to reach its own display features. It not easy for users to figure out the relationship between each other. * The blocks in same colors means their functions sync to each other

Problem 3 It’s hard to reach the main function buttons for users’ fingers such as “Power on/off” button.

Problem 4 The layout is in Traditional Chinese, so it’s not easy to use for users who don’t understand Chinese.

the control remote I re-designed..

Solution 1 According to the priority of each button and its feature, re-arrange their position and size. Priority 1: the sizes are the biggest, and the positions are the easiest for fingers to reach. Priority 2: the sizes are smaller than red blocks, and the positions are beside them. Priority 3: these two functions are used to adjust air, so I put them together. Their position are lower than red and yellow blocks. Priority 4: the sizes are the smallest, and the positions are also the lowest.

Solution 2 Put each button and its own display feature on the same side to let users connect them more directly. * The blocks in same colors means their functions sync to each other

Solution 3 Move the main function buttons such as "Power on/off" to the place which is easy to reach for fingers.

Solution 4 Replace Traditional Chinese with some universal patterns of graphic icons to be the new GUI. It’s easier to let people in different countries to use the same remote control.
