The interface includes other features, such as an options sidebar and filter searches, which allow users to make the experience more specific to their own needs. For example, users can add a via point into their journey if there is a particular route they wish to take or if have even more specific needs, are able to browse through a selection of local taxi companies which run in the area, allowing them to view information on each company before deciding whether or not to book with them. Users can also filter such searches by price range depending on their travel budgets and means users know how much the journey is going to cost them before booking.
The design of the interface includes a live time feed, allowing users to keep up to date with any changes in their travel time whilst other users book their own journeys. The design of this screen was based on the typical design of train and flight time boards found in stations, airports and even some bus stops. This element stays in a consistent place throughout the interface on the left hand side of the screen, allowing it to work more effectively in how most users would scroll through similar touch screen interfaces, predominantly using their right hand, linking to the idea that the larger part of the population are right handed. This also means the time feed is not hidden or distracted from by the current user's arm movements.
The type used for this was also chosen to reflect the typical style of such journey time boards, a style the public would be familiar with so allowing information to be more accurately communicated. This digital aesthetic means that times can be changed quickly through the movement of basic lines and dots so that users are constantly updated on their journey times.
A light blue colour has been used consistently through the design of this interface. This colour was chosen as it is known for producing a calming effect, which could potentially help to put users more at ease and not feel intimidated by it's design when using the interface. The colour is also known for being a symbol of intelligence in some cultures, reflecting on the system's knowledge, as well as the user's knowledge in that they will be able to get to their destination easily and safely, which overall can help to create a more friendly and comfortable experience for users.
In addition to this, the use of blue and yellow aspects could potentially produce a slight effect known as the contrast of complements, since these colours are close opposites on the colour wheel, meaning a suitable and complementary contrast between different elements is produced, and as a result enhancing the vibrancy of each.
Many elements of the final design of this interface, particularly those pieces of information which are framed, the corners of these have been rounded off. This has been done purposefully in order to enhance the friendly nature of the user experience and as a result, potentially put the users more at ease. The continuous use of this element also allows for consistency throughout the interface in terms of it's design. This aesthetic has also been applied to elements such as the keyboard, making the edge of the keys less harsh and intimidating, a decision which was based on research that suggested the original design of the traditional qwerty keyboard was to stop typists from hitting the keys too hard and jamming mechanical typewriters which would have been used at the time of development. This layout again helps with ease of use for the general public since this is a layout which they would be most familiar with. The typeface used for the characters within makes use of Helvetica Light, a typeface known for it's practicality and clear communication of information. This has also been utilised for other elements of type used throughout the interface, such as search and booking information.
