Stream Beam Coffee Machine Design for Interaction Factsheet What contextual factors (regarding the user, product, and user-product interaction) influenced your design? User profile as an experienced one that is open to discoveries is influenced the design with uncertainty. It also affected product style and appearance, while determining its range in market. Product context is mostly influenced with aesthetics and technology, blended into interaction process. Social factors are emphasized and product is intended to be exposed both when it is used and not used. Which domains of interaction are present in your product, and where? User-product domain is kept as main interaction domain, while interface is confined in a handheld part. Therefore with a remote-like controller, user-product-product interaction is considered as well. Lastly, thermochromic material selection enables an indirect way of user-product-user interaction. Marks on surfaces are created by users’ own preferences (such as heat, process time and sequence number) and therefore visually unique. A social and artistic way of coffee making is offered, where a barista can perform his act in front of an audience. How have you used product communication theory to guide users to perform intended interactions in an intended sequence? Visual language of product is designed with clean and bold lines to guide user to limited controls. Etchings and bumps are provided where user should have its hands on the product. Surfaces let handling and grasping. Also interface controls and lights provides a simple order for sequence and feedback. Pressing and touching allows user to control actions. Cautions are taken in order to prevent slips, such as steam mode being activated by first pulling downward. Without pulling, it does not steam even when pressed and squeezed. What kinds of experiences (aesthetics, meanings and emotions) do you intend your target user group to have whilst using your product? As a luxurious and technologically advanced product, Stream Beam is intended for experienced users that want to experiment their skills with simplicity. Like example of Leica cameras in photography, it aims to offer a visually superior product for contemporary kitchens with its streamlined sculpture look. Satisfying its user as a high-end espresso maker, with its usage qualities and sensual responses, Stream Beam aims to encourage its users to perfect their shots and coffees with uncertainty and lets user to try and discover new ways. Also with its technology and materials, it blends traditional techniques with modern ways of interaction. Emphasizing visual and tangible aesthetics, surfaces are created for touch and look at. Sensuality of coffee making process is enhanced with a multilayered experience. Transparency on water and coffee visualizes the process and brewed coffee is focused at hand. Which technologies have you included in the product to deliver its functionality and user experience? TUIs are included in product in order to provide a combination of digital and tangible interfaces at the same time. Touch surfaces along LED lights to communicate product status beneath the surface are used. Ambient light colors offers both functionality and adds to product environment and experience. Gestures are enabled for smoother movements. A pressure sensor helps with tampering action. Also rechargeable batteries are placed within portafilter-control. Alongside technologies, material choices are also aimed at enhancing the experience of coffee making. With glossy plastics, stainless surfaces with chromes finishes and transparent areas, product stands as a luxury appliance. Thermochromic materials are used on the top and front surfaces to deliver a unique experience each time with heat. Lastly, controller and device are synced via Bluetooth. Inspiration Inspired by the flow of water through coffee and coffee through portafilter, Stream Beam has its unique form in a streamline yet modern fashion. Flowing and glowing at the same time, it is created to appeal to senses. Operation / Flow / Interaction 1. Device is started by pressing on touch surface of controller for a couple of seconds. Lights start to glow both on controller and device. 2. Water level can be seen through transparent container. If below minimum, light on device blinks as a caution and it cannot be used before filling. 3. When system is heated and ready for brewing, light on device become a fuller circle. When hot water is circulated in device, top surface is affected by heat and marks are created on surface that circulates around main light. On side part, coffee steam is collected and water drips also create a texture with heat. This texture and amount of color change is affected by user’s preferences, such as temperature, pressure, sequence time and process repeats. 4. Selected coffee or pods are placed in portafilter. For tampering, it is put on place. When controller meets device, light on controller lightens fully for user to put finger on. A pressure sensor is activated for tampering, while user holds his finger and turns controller. 5. Coffee is tampered by an inner turning screw mechanism. After desired amount is set, button is released and controller is fixed on device. Circular light is activated and lights up clockwise to indicate hardening. 6. Coffee is tampered by an inner turning screw mechanism. After desired amount is set, button is released and controller is fixed on device. 7. Button is pushed once for an automated time sequence of pouring. Or user can hold push button for a manual time. This can be set as a preference. After a long day, one cup of coffee leaves marks with brewing, whereas for a group of friends, device and marks remain hot for a while. 8. For steaming action, piece is hold and pulled downwards. Light on device scales down to a point to indicate steam mode. Upper piece of nozzle is press squeezed for frothing the milk. Again, steam creates marks on side part. Espresso and milk can be used for different blends and machine is ready for new shots. With each continuing process, surfaces get hotter and colorful. The Creative / Research Challenge Challenge was to create a home barista experience where interaction between product and user should be designed to offer a unique way of making coffee.
