Applications of tactile interfaces to home automation for people in loss of autonomy : Training for memory gestures

Abstract : Tactile technologies are continuously evolving and now equip many devices. These systems can remotely control many functions of the housing to stay at home safely. However, an adequate solution requires an appropriation of the communicating objects by the user himself. The design of a remote controllable habitat requires the installation of a complex system. In this context, many applications of tactile technologies are emerging for people in loss of autonomy. Surveys show that few older people use touch interfaces (between 6 and 15% for people over 70 years against 83% for those under 35). The causes are lack of skills, lack of interest, fear of not being able to use it, health problems, or the cost of equipment. However, another French survey shows that, if the mobile phone is the tactile object the most commonly owned today, the most wanted tactile devices are equipments for disabled people (71%), followed by classical comfort home automation equipments. In this frame, tactile technology can be used more intuitively by elders and disabled people, because they are more intuitive. To improve tactile interfaces, it is important to take into account the memory of gestures, especially for people with reduced autonomy because the gesture used to interact with the interface is not always obvious. This implies that the functional signs (icons, buttons) and gestural modes of interaction (gestures required for a particular action) are fully embedded in their memories of daily practices. Because each handicap situation is unique, custom and updatable interfaces based on physical and mental skills of each user must be designed. To help disabled people to take possession of the interface and to reactivate their memory of gestures, several parameters must be taken into account: the continuous aspect of the gesture (to increase the sense of proximity to the object), a maximum contextual speed response and a minimum wait in the resulting action, the accuracy of the system response to the gesture, the adequate feedback of the interface. Tactile feedback information is detected by the surface layer of the skin and can thus be generated as vibrations, textures or temperatures. Depending on the level of autonomy and the ability of the person, the adequate interface can generate an effect of continuity between the user and his environment, an effect of harmony between his body and the interface. The interface is then experienced as an extension of the body of the user.
