Device and method for selection of options by motion gestures

A mobile device, comprising:

• a motion sensor configured to detect motion gestures;
• an audio unit configured to announce an input request and at least one option of the input request;
• a vibration unit configured to provide haptic feedback to a user by causing the vibration unit to vibrate to prompt the user for a selection confirmation;
• a display configured to display input request information and at least one option of the input request;
• a processor;
• and
• a memory storing instructions that when executed by the processor cause the mobile device to:
• audibly announce all content displayed on the display including a first input request and a first option of the first input request;
• upon audibly announcing the first option of the first input request, cause the motion sensor to detect motion of the mobile device as a first motion gesture;
• capture linear accelerations and angular velocities of the mobile device along at least two different axes of the first motion gesture;
• apply a fast Fourier transform to each of the linear accelerations and the angular velocities;
• apply a Baum-Welch algorithm to the fast Fourier transform of each of the linear accelerations and the angular velocities;
• obtain only five recovery parameters for each of the linear accelerations and the angular velocities from the application of the Baum-Welch algorithm;
• determine whether the first motion gesture corresponds to a first positive motion gesture or a first negative motion gesture by determining whether the first motion gesture meets a first motion threshold for the first positive motion gesture or a second motion threshold for the first negative motion gesture based on the obtained recovery parameters;
• in response to determining that the first motion gesture corresponds to the first positive motion gesture, initially select the first option as a response to the first input request, provide the user with at least one of auditory feedback and haptic feedback indicating that the first option has been initially selected, and prompt the user via the feedback to use a second motion gesture to confirm the initial selection of the first option as the response to the first input request, wherein the second motion gesture is a different type of motion gesture than the first motion gesture;
• cause the motion sensor to detect motion of the device in response to the prompt as the second motion gesture;
• determine whether the second motion gesture corresponds to a second positive motion gesture or a second negative motion gesture by determining whether the second motion gesture meets a third motion threshold for the second positive motion gesture different than the first motion threshold or a fourth motion threshold for the second negative motion gesture different than the second motion threshold;
• and
• in response to determining that the second motion gesture corresponds to the second positive motion gesture, select the first option as the response to the first input request and store the first option as the response to the first input request in the memory;
• and
• in response to determining that the first motion gesture corresponds to the first negative motion gesture, advance to a second option and audibly announce the second option.

A non-transitory computer readable medium tangibly embodying a program of instructions executable by a processor to cause an apparatus to:

• receive, via a communication interface of the apparatus, election ballot information including at least one contest and at least one candidate of the at least one contest;
• audibly announce a first contest and at least one candidate of the first contest;
• after audibly announcing the first contest and a first candidate of the first contest, detect a first motion gesture indicating a positive selection or a negative selection of the first candidate of the first contest;
• capture linear accelerations and angular velocities of the apparatus along at least two different axes of the first motion gesture;
• apply a fast Fourier transform to each of the linear accelerations and the angular velocities;
• apply a Baum-Welch algorithm to the fast Fourier transform of each of the linear accelerations and the angular velocities;
• obtain only five recovery parameters for each of the linear accelerations and the angular velocities from the application of the Baum-Welch algorithm;
• determine whether the first motion gesture meets a first motion threshold for a first positive motion gesture or a second motion threshold for a first negative motion gesture based on the obtained recovery parameters;
• in response to determining that the first motion gesture corresponds to the first positive motion gesture, initially cast a vote for the first candidate in the first contest, provide feedback indicating a preliminary selection of the first candidate as a recipient of the vote, and prompt, via at least one of auditory feedback and haptic feedback, a user to use a second motion gesture to confirm casting the vote for the first candidate, wherein the second motion gesture is a different type of motion gesture than the first motion gesture;
• detect the second motion gesture in response to the prompt;
• determine whether the second motion gesture corresponds to a second positive motion gesture or a second negative motion gesture by determining whether the second motion gesture meets a third motion threshold for the second positive motion gesture different than the first motion threshold or a fourth motion threshold for the second negative motion gesture different than the second motion threshold;
• in response to determining that the second motion gesture corresponds to the second positive motion gesture, storing the first candidate as the recipient of the vote for the first contest;
• and
• transmitting, via the communication interface, the stored vote for the at least one contest.
