Question
Imagine that you are the Information Technology Director of a major chain restaurant, and you have been assigned to design a menu ordering application that can run on all devices. Examine whether using a touch-screen monitor, a tablet, or using a mouse to select menu items to place an order would be most efficient. Speculate how employees would interact with these devices and the type of emotional reaction that customers and employees will experience while placing a beverage, appetizer or entrée order. 1: Differentiate between the interaction types and styles that apply to multi-touch screens and applications running on them.
Explanation / Answer
using touch screen monitor / a mouse would need a monitor to be stationed at a particular point while using the tablet order taking can be mobilized with many waiters carrying it and can take orders parallely.
Customers will not have to wait as the orders can be taken instantly which will add to the customer delight.
Interaction types :
Touch. The same as standard touch screen interactions, touch areas are made larger to accommodate a finger tip than those for mouse or trackball driven kiosks and exhibits.
Drag. With either one finger or multiple points, this type of interaction is similar to what we see with a mouse and pointer.
Pinch & Expand. This is an intuitive way to increase or decrease the size of objects in multitouch environments. In one case, we saw that just the act of placing a hand on the table surface slightly expanded an object (the hand opened a bit more as it impacted the surface). This allowed the visitor to immediately understand how to size the object. Pinch & Expand is common in ordinary hand gestures when talking about how big or small something is.
Rotate. As a visitor drags or pinches and expands an object it becomes apparent whether it can be rotated or not. Since multitouch tables have multiple points of approach, most applications provide visitors with the ability to rotate objects.
