Description
The scope of this document is to describe system design guidelines for the use of haptic interfaces to manage system safety and functional aspects of designs applicable for OEM and aftermarket systems in light vehicles. The intent of these guidelines is to help system designers determine when to use haptic interfaces and how to ensure their effectiveness. These may be stand-alone interfaces or the haptic aspects of multi-modal (audio, video, speech, haptic) interfaces. Excludes haptic systems designed for use by passengers, which may be addressed in a future version.
Purpose
To provide haptic interaction guidelines for system designers and integrators developing haptic systems intended for use by the driver of the vehicle.
In the “Use Cases” step, all the areas where haptic feedback could potentially be useful are enumerated and evaluated. The value proposition (i.e., advantages and disadvantages, cost versus benefit) of haptics in each use case is also examined in this stage. Questions like “does it make sense to add haptics here, just because we can?” are asked and answered. For example, while mechanical button replacement is often cited as a good use case for a haptic interface, it might not always be feasible or advisable to replace a button with a haptic surface. Sections 5 and 6 address this step.
Having established the value of haptic feedback, the next step, “Applications” is where the specific operating and interaction scenarios are defined and described (e.g., dashboard touch screen, steering wheel alerts, seatback alerts, etc.). User actions are defined for tasks requiring human participation (including sequence of activities, type of interactions, etc.), the system behaviors are described and the expected haptic responses from the system are defined, followed by the expected or desired human actions to the haptic responses. Section 6 addresses the exemplar applications of haptics.
The “Implementation” step lays out guidelines regarding haptic response characteristics such as the intensity levels of the response, the latency and duration of haptic feedback, the system considerations (actuator type, drivers, etc.) required to provide the response, any expected human responses to confirm or acknowledge the haptic response, etc. Section 7 addresses this step.
All the steps in the hierarchy shall be executed with the goal of satisfying appropriate safety requirements and user-friendliness characteristics.
