Surface User Interfaces
Figure 1: SharePic photo sharing system[1]
For example, the projected system shown in collaborative tabletop photo sharing system (SharePic [1]) allows older people the social sharing and story telling common with physical photos using digital photos. In SharePic, users do not feel they are using a computer to collaborate instead the media supports the actions directly. Ultimately, computer supported face to face collaboration will become so common place in bars, restaurants, schools, offices and homes that no one will notice its presence. It will be powerful and enhance our lives but it will be commonplace, obvious and boring.
Generally speaking, a Surface User Interface (SUI), is a class of user interface which relies on a self illuminated (e.g. LCD) or projected horizontal, vertical or spherical interactive surface coupled with control of computation into the same physical surface (e.g. a touch-screen). As with a tangible user interface the outputs and inputs to a SUI are tightly-coupled. They rely on computational techniques including computer vision, resistive membrane, capacitive and surface acoustic wave detection, to determine user input to the system. They are often used in public places (kiosks, ATMs) or small personal devices (PDA, iPhone) where a separate keyboard and mouse cannot or should not be used.
The scale of a SUI can range from small personal devices such as the iPhone or
PDA, through a Tablet PC up to large public interactive surfaces such as the MERL DiamondTouch or the Microsoft Surface. A SUI can rely on a range of input types including passive stylus, active stylus, fingers or tangible objects,or it may be tied to just one, as is the case with the Tablet PC with its active powered stylus. Where the input to the SUI is simply being used as a surrogate for a mouse input then many SUI applications function as classical GUIs do.
Useful example include
- Digital Desk
- MERL Diamondtouch
- Sony SmartSkin
- TANGerINE
- Microsoft TouchLight
- FTIR-based displays
- Microsoft Surface
- SMART table using Digital Vision Touch (DViT)
- LiveBoard
- HoloWall
- metaDesk
- UlteriorScape
- NUI Snowflake system (software system not hardware per se)
- Microsoft SecondLight
Issues includeing fatigue, the lack of haptic (e.g. force) feedback on such SUIs, cost, suitability has limited the adoption of large multi-user SUIs while small SUIs in iPhones, PDA, ATMs, Kiosks are commonplace. The coupling of personal displays with public shared displays remains an area of active research [2].

Apparently, work is underway to develop the system for medical applications, e.g. enabling 3D imaging of CT scans.

UK case study
One system that is being introduced is called Choose and Book - the basic idea being that a GP can use the system to request an appointment for a patient with an appropriate specialist. The system is meant to increase choice for patients because they can see the range of locations where they could go.
I just came across this news article on the system.
Reading it made me think about the challenges of evaluating such a system but also the importance of doing so. If different health care providers are implementing and engaging with the system in different ways, there is the potential for huge variation in impact on the process of care. But it also means its important to understand the relationship between how the system is implemented (including features of the implementation process such as training) and its subsequent impact on the process of care.
Making use of the blog
I just wanted to take this opportunity to encourage all of you to make use of the blog as you see fit, whether it's:
- Posting links that you think will be of interest to the workshop participants, regarding new technologies, relevant research, interesting case studies;
- Advertising relevant events such as workshops and conferences;
- Reporting on research you're undertaking;
- Posting a topic for discussion.
