Workshop: Guidelines for Haptic Lo-Fi prototyping

19th of October (Sunday)

Haptic interfaces, making use of gesture and pressure, force feedback and tactile displays, together with audio and visual feedback, offer the opportunity to present dynamic "perceptualizations" of information. While the use of lo-fi paper prototypes to explore visual interface solutions is well established in HCI, it is not so clear how to do something similar for an interface involving haptics. This becomes particularly challenging when modalities such as haptics and audio are not used as just enhancements of the visual design, but, instead, are designed as major information sources. The ability to produce early prototypes is needed not only for the exploration and evolution of the design space, but also for making it possible to build the necessary bridge between users and design early in the process. Without the possibility to make early haptic prototypes the same kinds of interaction problems are likely to occur as happened in the past for visual interfaces, where users were only exposed to designs right at the end of the development process. The aim of the workshop will be to explore the possibilities of lo-fi haptic prototyping to see what is feasible, if effective prototypes can be made and the requirements for a lo-fi haptic prototyping method.

The success of the Wii and the iPhone together with the development of low-cost force feedback devices have put haptic feedback within the scope of the individual user. Hence, there is an increased need to develop heuristics, guidelines and standards for its use. This workshop will bring together 15-20 practitioners from industry and academia focused on establishing a method and guidelines for the use of lo-fi haptic prototyping in the early design phases of perceptualization and interaction.

The first part of the workshop will emphasise the current methods used during early design (as well as ideas for improvements) demonstrated by the participants, as this is a central aspect of the workshop that would not be possible during a paper session or with a larger gathering of attendees. These demonstrations will be used to stimulate discussion and brainstorming within the group. On the second part of the workshop, participants will get "hands on" to rapidly create physical prototypes using everyday materials  (provided at the workshop location) together with Wizard of OZ type techniques as a means of illustrating potential design solutions established by the group. Finally the hands on work will be taken as a starting point for a discussion on suggesting guidelines for how to incorporate haptics into the early phases of the design process.

Submission

Participants are expected to contribute short presenations/demos illustrating ideas or examples (10-15 minutes). Papers (maximum 2 pages using the NordiCHI short paper format) should be submitted by the 22nd of September. Submissions should be sent to charlotte.magnusson@certec.lth.se .
