ENHANCING YOUR DEVICE DESIGN THROUGH TACTILE FEEDBACK
As with any UI element, haptics must be designed thoughtfully in order to achieve the desired experience. Users expect the sight, sound and feel of their experience to be consistent, rational and integrated. The combination of haptics with audio and visual UI can be breathtakingly effective if all these components work together, but can be confusing if poorly designed. To help guide the developer through the process, we’ve created a series of design recommendations for the most commonly implemented Gestures.

Manufacturers have installed haptics in hundreds of millions of touch-screen consumer devices, and the technology is becoming increasingly important in the hand-held market as vendors strive to differentiate their products and win customer loyalty. A broad range of technology options are available. This article summarizes the hardware and software comprising a haptic system, and the technical factors that must be considered when selecting an actuator technology for a hand-held device.

The purpose of this paper is to discuss the importance of mental models to the mobile user interface and the role that new technologies, such as high-definition haptics, can play to enhance a consumer’s mental model of a specific mobile application and their appreciation of it. The paper illustrates ways designers can use HD haptics to influence mental models for mobile applications to make virtual activities more realistic and engaging for the user and to differentiate their products in the marketplace.

This paper presents findings from a controlled study conducted to establish, through quantitative and qualitative research techniques, the value consumers give to the integration of haptics features in mobile phones. Download the white paper (PDF) The research was designed to ask the following questions: Do users like haptics in their mobile devices? How do they respond to different levels of haptics, such as low-resolution haptics features now available in phones, or high-definition (HD) haptics features that provide more refined effects? Can HD-enabled applications be used to influence user preference for a product? Are the haptics technologies now used in the industry sophisticated enough to interest the market or do HD haptics provide a better user experience? How will consumers respond to next-generation HD haptics applications? As reported in this paper, consumers strongly appreciate haptics-enabled features for their mobile phones. The paper summarizes the study’s leading conclusions, the methodology used in the research and its most important findings, along with recommendations that can be used to guide application development with haptics technologies.
“Tactile Feedback in Mobile: Consumer Attitudes about High-Definition Haptic Effects in TouchScreen Phones,” by C. Ullrich, D. Sheehan, D, Birnbaum, T. Martin, Feb 2011.
Mobile application developers should not be concerned that haptic effects will impact a handset’s battery life. New research conducted by Immersion Corp. found that haptic technology power consumption is not significant in mobile devices, even when haptic effects are employed under very aggressive usage scenarios. Researchers assessed the impact on battery capacity for six popular applications that use a range of haptic technologies from Immersion Corp. as well as the generic Vibe technology included in Android devices. They also evaluated the power consumption of three smart phone applications used on an Android phone with and without haptics engaged; the haptics used in this second study were supplied by Immersion.
