We present the form factor design iteration process of the Gesture Watch, a wearable gesture interface that utilizes non-contact hand gestures to control mobile devices while non-visual feedback is provided from its tactile display. Based on limitations discovered from a previous prototype, we identified three design challenges: wearability, mobility, and tactile perception. In addressing these challenges, we focus on three main parts affecting the form factor: the sensor housing, the strap, and the motor housing.

“…Clothing accessories that are worn on the wrist, such as watches, can be easily embedded with electronics to provide input capabilities [6,15,17]. Bauman et al built a series of electromechanical wristbands of various haptic expressive capabilities to study means to grab a user's attention through touch [1].…”

We present a haptic wristwatch prototype that makes it possible to acquire information from a companion mobile device through simple eyes-free gestures. The wristwatch we have built uses a custom-made piezoelectric actuator combined with sensors to create a natural, inconspicuous, gesture-based interface. Feedback is returned to the user in the form of haptic stimuli that are delivered to the wrist. We evaluated the capabilities and limitations of our prototype through two user experiments. One experiment verified that the apparatus could be used as a tactile notification mechanism. The other experiment assessed the feasibility of using a cover-and-hold gesture on the wristwatch to obtain numerical data tactually. Results from the numerosity experiment and feedback from participants prompted us to redesign the cover-and-hold gesture to provide users with additional control over the interaction. We qualitatively evaluated the redesigned interaction by handing the prototype to users so that they could use it in a realistic work environment. Taken together, results from the experiments and the validation process indicate that a wrist accessory can be effectively used to perform discreet, closed-loop, eyes-free interactions with a mobile device.

“…Paneels et al [11] designed a tactile display having six actuators in a circular configuration and showed that circular or alternating lateral movements aided perception. Lee and Starner [6] designed a 4×4 tactile display on the wrist and showed that it could deliver various patterns with a high average accuracy.…”

Investigating the Information Transfer Efficiency of a 3x3 Watch-back Tactile Display

A watch-back tactile display (WBTD) is expected to be a viable supplement to the user interface limitations of a smartwatch. However, its design requires that many design parameters such as tactor types and stimulus patterns be determined. We conducted a series of experiments to explore the design space of a WBTD consisting of 3×3 tactors. We demonstrated that tactor types and the temporal patterns and locus of a stimulus produce statistically significant effects on the efficiency of a WBTD. The experimental results can act as a practical guideline for the design of an efficient WBTD. Author KeywordsWatch-back tactile display; 3x3 tactor array; information transfer efficiency.
