Abstract

The present invention provides a technique that utilizes a mobile device attached to a user’s arm and allows manipulation of the mobile device without touching. The technique described herein allows the user to manipulate the mobile device by slight head movements and minimal hands gesture. The mobile device is equipped with functionalities to track the user`s head movements and to estimate the distance between the mobile device and the user’s head. Also, the device is equipped with a proximity sensor, a magnetic sensor or a camera which provides information and allows the users to manipulate the mobile device without touching the mobile device.

TECHNIQUE FOR OPERATING A MOBILE DEVICE ATTACHED TO USER'S FOREARM

BACKGROUND

The present invention relates generally to a mobile device and more particularly to a method and apparatus to operate the mobile device without touching the mobile device attached to a user’s forearm.

Mobile devices, such as tablets and smart phones are very useful for users who perform multiple operational tasks at one time. These users derive various benefits from the mobile devices. For example, the user may need to check supplemental information for his task, talk to someone in a remote area and send reports to a server about the task, while the task is being done.  

One of the challenges of using such mobile devices during field work is that there are some situations where the user cannot hold the mobile device or is unable to touch the mobile device.  For example, when the users are executing operations with both arms, or if the users wear gloves, they cannot touch the mobile devices even if one hand is free, or when the user`s hands are wet or not clean.

A conventional technique includes use of head-tracking movement for interactions with a mobile device.  However, conventional head tracking movement do not focus on the mobile devices specifically. A user may provide input to the device by performing actions such as tilting the device, moving the user's head, making a facial expression, or otherwise altering an orientation of at least one aspect of the user with respect to the device.  The tilting or shaking the mobile device may not have so many interactions. Another conventional technique describes the use of the mobile devices by detecting hand gesture of the users.  However, the gesture recognition may not be accurate and also so many interactions are not possible.

It would be desirable to have a technique for operating a mobile device attached to the user’s forearm without touching or when the user`s hands are wet or not clean.

DETAILED DESCRIPTION

The present invention provides technique for operating a mobile device attached to a user’s arm without touching to the mobile device. The technique allows the user to manipulate the mobile device by slight head movements and minimal hand gestures.

Figure 1 depicts the mobile device attached to the user`s forearm. The mobile device is equipped with functionalities to track the user’s head movements and to estimate distance between the mobile device and the user’s head.

According to the technique described herein, the mobile device is attached to the users’ forearm and the user does not need to hold the mobile device in palm to operate the mobile device.  In addition, the technique eliminates the need of carrying bags for the mobile device even when the mobile device in not being used.
