# User Feedback

## Overview

<table><thead><tr><th width="223">Feature</th><th>Description</th></tr></thead><tbody><tr><td>Auditory Feedback</td><td>The <code>BeepOnInvalidInput</code> property enables a beep sound when a user attempts an action that is not permitted (e.g., interacting with a read-only control).</td></tr><tr><td>Visual Shake Animation</td><td>The <code>Shake()</code> method triggers a shake animation to visually indicate that an attempted action is invalid, reinforcing the feedback mechanism.</td></tr></tbody></table>

***

### Key Points

<table><thead><tr><th width="264">Aspect</th><th>Description</th></tr></thead><tbody><tr><td>Immediate Sensory Cues</td><td>Users receive immediate feedback through both sound (when enabled) and visual shake, which helps in quickly understanding that their input is invalid.</td></tr><tr><td>Configurable Auditory Signal</td><td>The <code>BeepOnInvalidInput</code> property allows developers to toggle the auditory feedback based on application requirements or user preferences.</td></tr><tr><td>Clear Visual Indication</td><td>The shake animation provided by the <code>Shake()</code> method serves as a clear and noticeable visual indicator that an interaction was not accepted.</td></tr><tr><td>Integrated with Interaction</td><td>Both feedback mechanisms are integrated into the control’s interaction logic, ensuring consistent user experience across various interaction scenarios.</td></tr></tbody></table>

***

### Best Practices

<table><thead><tr><th width="308">Practice</th><th>Recommendation</th></tr></thead><tbody><tr><td>Enable Auditory Feedback When Appropriate</td><td>Use the <code>BeepOnInvalidInput</code> property in contexts where an audible cue can enhance the clarity of invalid interactions, especially in high-interaction scenarios.</td></tr><tr><td>Combine Feedback Mechanisms</td><td>Consider using both auditory (beep) and visual (shake) feedback to ensure that users are aware of invalid actions, particularly in environments with distractions.</td></tr><tr><td>Test Feedback on Multiple Devices</td><td>Ensure that the auditory and visual feedback behaves consistently across different hardware configurations and operating system sound settings.</td></tr><tr><td>Provide User Settings Option</td><td>Allow end users to disable or customize feedback through your application settings if the default sensory feedback is disruptive or undesired.</td></tr></tbody></table>

### Common Pitfalls

<table><thead><tr><th width="241">Pitfall</th><th>Explanation</th><th>How to Avoid</th></tr></thead><tbody><tr><td>Overusing Feedback Mechanisms</td><td>Excessive use of beep sounds and shake animations can become distracting or annoying to users.</td><td>Use these feedback mechanisms sparingly and only for clearly invalid or prohibited actions.</td></tr><tr><td>Inconsistent Feedback Behavior</td><td>Failing to trigger feedback consistently (e.g., only visual but not auditory) may confuse users about what actions are invalid.</td><td>Ensure both the <code>BeepOnInvalidInput</code> property and <code>Shake()</code> method are properly integrated into the control’s interaction events.</td></tr><tr><td>Ignoring User Preferences</td><td>Not providing an option for users to disable the feedback might lead to a negative experience, especially for users sensitive to sound or visual effects.</td><td>Consider implementing user settings that allow disabling or adjusting the intensity of feedback.</td></tr></tbody></table>

### Usage Scenarios

<table><thead><tr><th width="247">Scenario</th><th>Description</th></tr></thead><tbody><tr><td>Read-Only Interaction</td><td>When the control is set to read-only, enabling <code>BeepOnInvalidInput</code> and calling <code>Shake()</code> on invalid input reinforces that changes are not permitted.</td></tr><tr><td>Input Validation in Forms</td><td>In forms or surveys, invalid interactions (such as trying to select a rating when not allowed) can immediately prompt feedback to guide the user.</td></tr><tr><td>Accessibility Enhancement</td><td>In situations where immediate feedback is critical, using both auditory and visual cues ensures that all users, including those with disabilities, receive clear signals.</td></tr></tbody></table>

#### Code Sample: Enabling User Feedback

```csharp
// Initialize the emoji rating control
SiticoneRatingEmoji ratingControl = new SiticoneRatingEmoji();

// Enable auditory feedback for invalid interactions
ratingControl.BeepOnInvalidInput = true;

// Example usage: If a user attempts to interact in read-only mode, trigger shake and beep feedback
if (ratingControl.IsReadOnly)
{
    ratingControl.Shake();
    if (ratingControl.BeepOnInvalidInput)
    {
        SystemSounds.Beep.Play();
    }
}
```

***

### Real Life Usage Scenarios

<table><thead><tr><th width="297">Scenario</th><th>Description</th></tr></thead><tbody><tr><td>Customer Feedback Applications</td><td>In feedback forms, if a user accidentally tries to change a rating when modifications are not allowed, the combined beep and shake feedback immediately informs them of the restriction.</td></tr><tr><td>Interactive Kiosk Systems</td><td>Public kiosks often benefit from clear feedback when users try to perform actions that are restricted, ensuring a smoother user experience and reducing confusion.</td></tr><tr><td>Educational Software</td><td>Applications used for training or assessments can use such feedback mechanisms to teach users the correct ways to interact with the control by highlighting errors instantly.</td></tr></tbody></table>

#### Code Sample: Integrating Feedback with Read-Only Controls

```csharp
// Configure the control as read-only for a certain user role or application state
ratingControl.IsReadOnly = true;

// Handle mouse or key events that attempt to change the rating
private void ratingControl_MouseDown(object sender, MouseEventArgs e)
{
    if (ratingControl.IsReadOnly)
    {
        // Trigger shake animation and beep feedback
        ratingControl.Shake();
        if (ratingControl.BeepOnInvalidInput)
        {
            SystemSounds.Beep.Play();
        }
    }
}
```

### Troubleshooting Tips

<table><thead><tr><th width="307">Tip</th><th>Recommendation</th></tr></thead><tbody><tr><td>Feedback Not Triggering</td><td>Verify that the <code>BeepOnInvalidInput</code> property is set to true and that the <code>Shake()</code> method is being called in the appropriate event handlers.</td></tr><tr><td>Excessive or Distracting Feedback</td><td>If users find the feedback overwhelming, consider reducing the frequency of feedback triggers or providing options to disable them in your application's settings.</td></tr><tr><td>Sound Not Playing</td><td>Ensure that the system sound settings allow for playback and that no exceptions are occurring when calling <code>SystemSounds.Beep.Play()</code>.</td></tr><tr><td>Visual Feedback Delay</td><td>If the shake animation appears delayed, check the animation timer settings and ensure that the control’s <code>Invalidate()</code> method is called to update the UI promptly.</td></tr></tbody></table>

### Review

<table><thead><tr><th width="308">Aspect</th><th>Comments</th></tr></thead><tbody><tr><td>Immediate User Acknowledgement</td><td>Combining auditory and visual cues helps users understand when an invalid action is attempted, reinforcing proper usage of the control.</td></tr><tr><td>Configurability</td><td>The ability to toggle feedback via <code>BeepOnInvalidInput</code> and the explicit invocation of <code>Shake()</code> gives developers control over the user experience.</td></tr><tr><td>Seamless Integration</td><td>Integrates naturally with the control's other features, ensuring that feedback is part of the overall interactive design.</td></tr><tr><td>User Experience Impact</td><td>Properly implemented feedback improves usability and reduces user frustration by immediately indicating that an action is not permitted.</td></tr></tbody></table>
